Russian electronics engineers honestly answer journalists and readers

Hello! With you are the engineers of the Russian Research and Production Association "Design Bureau Datacam" and personally the technical director of the enterprise - Vladislav Mekhantsev.

Datakam< /p>

Not so long ago, an editorial was published on this site devoted to the analysis of the Datakam DVR and its comparison with three models of other popular brands. We carefully read the opinion of a Mobile-Review.com journalist regarding our production, studied what readers wrote in the comments and decided to present our own view of the past event. In addition, in the first person, we will honestly answer the most tricky comments on the Mobile-Review.com material.

Yes, we place this material "as an advertisement", but solely for the purpose of expressing our own point of view here as a manufacturing company. We are an honest brand, and therefore we will not even try to disguise advertising as editorial material. (Especially since no one would have allowed to do this on Mobile-Review.com.) So those who categorically do not accept such a format can simply not read further - we do not impose our point of view on anyone.

Datakam< /p>

In the comments, readers primarily criticized us for the testing methodology. Like, what kind of comparison is this: we drove for 20 minutes in a car with registrars, and then dismantled the cameras to the screws. Night shooting is also needed!

For starters, let's say that the comparison made is by no means the basis for the final choice in favor of one or another model. We did not try to tell everything that is possible so that readers of the articles immediately after reading ran to buy one of the tested registrars. There are hundreds of methods for matching such devices. We have proposed only one method, which no one has implemented before us. The bottom line is to evaluate the level of the model based on the quality of the components and the thoroughness of the assembly. And the answer to the question why no one has done this before is obvious enough: for many brands in the registrar market, the result of opening their products can say little in their favor.

Shooting at night? Of course, for a full-fledged comparison of video quality, recording at night is also needed. And in two versions: with roadside lighting and without it. It would be necessary to compare the video at dusk, and also in the rain, snow. And all these weather conditions would be worth shooting at night, during the day, and at dusk. Each scenario without exception - both within the city and on the country road. There would be a huge comparison matrix in different lighting conditions, and such a test would be 100% objective. There is no limit to perfection, but conducting such a number of tests is expensive and unrealistic: you will have to spend a lot of time (your own and someone else's) and a mountain of money. Plus, there is no way we can force summer to suddenly turn into winter :) Among journalists, we have not yet met advocates of such thorough multi-week testing either. Typically, registrar tests are selective and fairly typical surveys. We looked at the models externally, compared the buttons-menu-characteristics, half an hour on the road, examples of day-night video - and you're done.

Datakam< /p>

Our approach to the development and production of recorders is directly spelled out in one of the five principles of KB Datacam: "Any savings on components and reduction in the cost of materials during manufacture are prohibited." We were really interested to know - how are things going with other manufacturers? First of all, two other representatives of the top segment, which offer the consumer very expensive devices. With the last budget participant in the comparison, everything was initially clear - the registrar turned out exactly for his little money. Such a typical Chinese product that can even record videos quite well and entices with sonorous characteristics on the box. But in reality, due to the specific approach to the work of both Chinese developers and Russian resellers, the buyer gets the opportunity to play the game “Will the registrar let me down at the most crucial moment?” and “How many months (or even weeks?) will the device last in real operating conditions?”.

With confidence, without undue modesty, we declare that we make cool, one of the best (if not the best!) home DVRs among all sold in Russia. And so we boldly decided to conduct such an analysis of devices to the screw.

You, dear readers, will object - a good product does not need advertising. Perhaps there are people in the world with telepathic abilities who receive all the information directly from space. Probably, such citizens already know about our company - NPO "KB Datakam", our registrars, who develops them and how, why they are fundamentally better than their analogues. But there is an opinion that there are very few such "experts-telepathists". We, the manufacturers of Datakam recorders, live in the real world. And therefore - yes, we use all kinds of information channels to "reach out" to the consumer and tell about what wonderful things we have been designing for the last three years. What we put our engineering mind, talent and soul into, all our seething creative energy.

I would like to apologize to the readers for the quality of the registrars-opponents. Before the event, there was no “preparatory analysis” - we chose the models and, together with the journalists, saw for the first time what was inside the devices. And we are not to blame that our colleagues in the market have done a lot of obvious "jambs".

Datakam< /p>

A side note - if you think Datakam recorders are very expensive, then... You are absolutely right! In the comments to an article about our analysis on a popular automotive site, one commentator furiously argued that registrars with a high price, in principle, were not needed by anyone. We quote: "The consumer will still give preference to the budget segment." True, a little later it turned out that the comrade himself drives an old Zhiguli for 60 (!) thousand rubles. Not surprisingly, he considers registrars worth almost a quarter of his car's price tag to be an unjustified luxury. Yes, we agree in advance with such consumers: our Datakam G5 will definitely not suit them. If translated into the language of smartphones, many consumers simply cannot afford Apple devices. But this does not mean that the world has converged on cheap Android-Chinese phones, and the Cupertino product is a whim and a whim of a handful of rich metropolitan majors.

And remember - if you categorically did not like our methodology with a comparative analysis of registrars, you can always read other materials, reviews on Datakam G5. Right on our website, we have collected almost fifty detailed articles from a variety of Internet resources in a separate list. In these articles, information is just given in the usual way: a button on the left is a button on the right, a connector on the left side of the case - another connector on the right side of the case, etc.
And, by the way, there are numerous examples of real video, taken by our camera.

Now let me give you a few, from our point of view, extremely important clarifications to the very editorial article of the Mobile-Review.com journalist. The process of comparing the registrars took about 6 hours - it is not surprising that the journalists could not fit many points into their extremely limited reports. We, in turn, did not interfere with the author's opinion of the portal - the journalist wrote about what he saw himself. And about what he himself considered necessary to write. Unfortunately, many key (in our opinion) points were not covered.

Datakam< /p>

In general, we decided to supplement the material as advertising. Precisely because I want to talk about many more important points, and it is unlikely that it will be possible to invite journalists on the same occasion a second time - they are busy people and not only write about registrars. This is not a "one-sided" dialogue - comments on our publication, as always, are open. Please, express your opinion about what you read and about our products in the comments.

In order not to confuse the reader, our material will follow the same structure as the original report on Mobile-Review.com, with quotes from it.

Datakam< /p>

As you understand, in this article we cannot directly call our competitors by their proper names - this would be a direct violation of the Advertising Law. So you have to get by with conventional names. Let's call the Taiwanese registrar in the orange box "Brand No. 1", the South Korean device without a screen - "Brand No. 2", and let the purebred Chinese from Russian resellers be "Brand No. 3". By the way, the top Korean "Brand No. 2" was added to the testing specifically "by request of readers." In the comments to articles about our first event, many people expressed their desire to see the insides of this particular device.

Positioning and principles for selecting devices for testing

"Datakam - device development - Russian office, assembly is now carried out in Taiwan."

Datakam recorders weren't just made in Taiwan. There was its own assembly shop "KB Datakam" with a capacity of up to 10,000 devices per month.

Of course, the employees themselves are Taiwanese, but three Russian process engineers who permanently resided in this Asian country led and monitored all the processes. And by the time this material was published, we had moved the SKD assembly of Datakam recorders to Moscow. By the end of 2015, we plan to increase the degree of assembly localization of our devices to 70%. Due to the fact that we will “take away” part of the operations from foreign suppliers of components. At the same time, we will carry out the process of increasing the share of domestic assembly very carefully and gradually, so as not to lose quality in any case. After all, the country where the registrar gathers is secondary for the consumer. Primarily - the quality of the assembled device.

Datakam< /p>

The transfer of the assembly to Moscow was carried out both for patriotic (tired of working with the Chinese, who always strive to deceive and substitute, to be honest!), And for purely mercantile, economic reasons. The widespread belief that the Chinese are willing to work for pennies has long been a myth. A good qualified Taiwanese (Chinese) assembly line assembler values ​​himself at least $700 per month (about 40,000 rubles at the current exchange rate). In Russia wages are not lower. But instead of an illiterate person who speaks a different language, we get a savvy employee with a good technical education and a 100% complete understanding of the matter. Plus, we don’t have any “language barrier” with the Russians, which needs to be painfully overcome in the case of the Taiwanese-Chinese.

We also note that the import of components, rather than finished devices, reduces the cost of the registrar by 20% - we simply save on taxes. We save, we note, in a legal way! This allows KB Datacam to keep the prices of its devices almost at the pre-crisis level, although the price tags for components have almost doubled since the pre-crisis times.

In the near future, we will probably tell you more about how Datakam models are assembled in Russia. In the meantime - a small story from the reporters of the NTV channel:

“Brand No. 3 was chosen solely on the basis of price, combined with the similarity of characteristics, this is a fairly typical model for the Russian market.”

Let's say even more - the chosen "Brand No. 3" personifies the bulk of registrars on the shelves of large Russian retail chains. The very models that are completely (from designing boards to screwing screws into case parts) are created by Chinese developers (Samoon factory, for example). At best, they are slightly improved by order of domestic brands. In place of this sample could be almost any registrar of almost any umbrella brand. Umbrella - that is, a brand that does not specialize in registrars, but produces a wide variety of devices: from MP3 players to electronic photo frames and vacuum cleaners.

There are enough brands on the registrar market, under which many different models are produced, assembled at the same factories. Let's give a hint: if there are more than 3-4 models in the current brand line, and the assortment is updated more often 1-2 times a year, then you have 100% resellers gluing their nameplate to a Chinese product.

Datakam< /p>

We are by no means saying that this is bad - there is a buyer for every device. The same Brand No. 3 registrar costs only 5,540 rubles, which is almost 2.5 times cheaper than our Datakam G5. One of the goals of the analysis was to show how such savings are achieved and whether the consumer is really getting a bargain. Naturally, each consumer decides for himself what is more important to him. Or a guarantee of the reliability of the device, which will not delete important files and will not stop shooting at the most crucial moment. Or a lower price, without a full understanding of how it was achieved by the device manufacturer.

“Brand No. 2 is noticeably out of the ordinary because it has no screen and is focused on interaction with a smartphone. In addition, most of the premium offerings are for dash cams designed to replace the interior rearview mirror, and comparison with them would simply be incorrect.

Despite the lack of a screen, the Brand #2 recorder is still closer to classic portable models like the Brand #3 device and Datakam than top-end rear-view mirror recorders. That is why "Brand No. 2" was chosen. Plus, because this Korean brand is one of the most "fashionable" in the domestic registrar market. It was interesting for us to see how the products of Brand No. 2 look from the inside, and at the same time to compare the device with the brainchild of Russian engineers (that is, us) - Datakam G5. We ourselves were amazed by the reality, which we described in detail above - in fact, consumers are being offered the old model on four-year-old boards under a new name.

Datakam< /p>

Device Specifications

Let's give a table that, in our opinion, most correctly reflects the parameters of the registrars.

Users often wonder why our cutting-edge Datakam G5 uses the seemingly outdated Ambarella A5 processor and not the latest A7? To begin with, let us explain that A5 and A7 are the common names for the lines of “stones”. There are about a dozen versions of the Ambarella A7. For example, in the Brand No. 3 device, one of the “youngest” options, Ambarella A7LA30, is installed. Which in terms of performance is no better than the "stock" (that is, the stocks of which are still on the market for components in large quantities) the A5 series processor that we use in the Datakam G5.

However, it is worth recalling that KB Datacam is the only manufacturer of registrars in Russia and the CIS who has a direct contract with Ambarella not only for the supply of processors, but also for the development / improvement of software for them. Engineers from the USA and Russia have been and are engaged in “deep tuning” of Ambarella A5 for Datakam G5 together. And they do it so successfully that over time, the planned need for an immediate transition to the Ambarella A7 platform disappeared from KB Datacam. The record bitrate of 20 Mbit / s achieved by KB Datacams on the “five” was only repeated in Go *** cameras (sorry, the law “On Advertising” prohibits naming foreign brands), and even then due to the exclusive processor from Ambarella. Meanwhile, Datakam has a new record on the way - 30 Mbps. It will be installed in one of the upcoming registrars in 2015.

Datakam< /p>

Datakam G5 DUO - two cameras, record 30 Mbps, Ambarella LA85, Wi-Fi and Bluetooth. Look forward to autumn 2015!

Packaging and accessories

“Brand No. 1 has a bundle that is not much inferior to the premium segment, although the box itself is simpler.”

Not that it was very critical, but we did not find a banal USB-microUSB cable in the package of the most expensive Brand No. 1 registrar. It's a shame that the manufacturer stinted on such an inexpensive, in fact, penny accessory. For example, Brand No. 2 took care of the user, a card reader is attached to the registrar.

Datakam< /p>

In our opinion, a responsible manufacturer should pay attention to the quality of not only the registrar itself, but also the accessories. From fastening to glass to hooks on which wiring stretches through the interior of the car. For example, hooks for laying cables in the cabin have the most modest dimensions in comparison with the options from the configurations of other registrars in the test. This is a natural consequence of using a thin power wire, so that during installation the cable can be put into any slot in the cabin.

Datakam< /p>

Cable hooks, left to right - Brand #2, Brand #3, Datakam G5

And we did not save on the handbag, as our basic principles require. The accessory is made of natural suede, the main part is made of eco-leather, which is extremely difficult to get dirty. A similar accessory of "Brand No. 1" is entirely fabric, which is why it instantly collects dust and dirt.

Datakam< /p>

Dimensions and placement in the cabin

"If we look at power adapters, then the fact that G5 only has a detachable power cable.

This solution has an indisputable plus - if the driver touches the wire, then in the case of the Datakam G5, the cable will only fly out of the adapter connector.

Datakam< /p>

If the end of the cable is soldered to the inside of the block, as in the case of "Brand #1", "#2" and "#3", it is possible to completely tear the wire from the board right "with the roots". The durability of such a design, obviously, will be lower. And the risk of accidental damage to the accessory during operation is higher.

Literally in passing, the unique Datakam mount on neodymium magnets was mentioned in the material. From our point of view, it is worth dwelling on this feature of our devices in more detail.

This is really our author's development, its analogues simply do not exist yet. It is too expensive and difficult for Chinese factories to develop or even copy such a holder. It is on the basis of borrowing the idea with a magnetic holder that we will definitely be able to determine in the future when the Chinese will seriously take up the “cloning” of our device. The second similar “flag” will be copying our branded blend filter (see below for more on it).

We managed to create, perhaps, the only mount that is called a quick-release mount without reservation. Any other holders in registrars require certain manipulations to remove or install the camera.

“On the side of the “Korean” - maximum compactness, on the side of the “Russian” - great versatility, which is important for someone who, for example, acquires a registrar for the first time.

We would like to draw your attention to the fact that the device of the Korean "Brand No. 2" is the only one of the four recorders that is completely devoid of the ability to turn to the side. So, the driver generally does not have the opportunity to film what is happening to the left or right of the car, it is normal to capture a conversation with the inspector. The Datakam G5 mount allows you to almost instantly turn the camera sideways exactly 90 degrees or all 180 degrees at once. Brackets "Brand No. 1" and "No. 3" are based on a hinge, which allows you to quickly change the direction of the recording of the registrar. That is, these brackets are also definitely more effective than the Brand No. 2 fixed mount.

Behavior on the road, video

"Models from Datakam, Brands #1 and #3 greet you with their voice and turn on the screen."

At the same time, in our opinion, a more successful phrase is chosen in the Datakam G5: every time the registrar wishes the driver “Good luck!” and thereby sets the motorist in a positive way. The Taiwanese model is limited to the dry message "Welcome to the No. 1 Brand DVR."

“The result was slightly worse (compared to Datakam - approx.) by Brand No. 1. Despite the fact that the location of the camera turned out to be not very successful and the reflection in the windshield got into the lens, the distance when determining the number of an oncoming VAZ turned out to be only slightly less than that of the Datakam G5. Most likely, if you choose a better location, the result would be the same at all.

Especially so that readers can evaluate the quality of the image in a test 5-minute race, we put the source video files of Datakam, devices "Brand No. 1" and "No. 2" into free access. You can download the archive here. Remember that it is not worth evaluating the quality of videos on YouTube videos - the video service strongly compresses files in order to reduce their size. Therefore, we are not talking about demonstrating the original quality of the video. See only original files!

As you can see in our tests, which we conducted in the presence of journalists and bloggers, the registrars are almost in the best conditions - the bright sun is shining, almost complete cloudlessness. Occasionally, the leadership in the legibility of license plates of cars could change, mainly at short distances. However, in most cases, our Datakam G5 won. And this is not fake or advertising - the tests were carried out in the presence of journalists. Videos were also analyzed on the spot with the participation of media representatives.

The main problem of the Brand No. 1 device is the frequent frank blurring of license plates, when there is not even a chance to see the outlines of letters or numbers. And it is clearly seen that no matter how you choose a good installation angle on the windshield, you will not get the same result as the Datakam G5 for the Brand No. 1 model.

Datakam< /p>

Datakam< /p>

Datakam< /p>

We also want to dwell separately on such a Datakam G5 branded "chip" as a removable blend filter. The editorial talks about it, but we want to add more details.

Datakam< /p>

This hybrid accessory was created by our KB Datacam engineers. And no other manufacturer has yet offered even a remotely similar alternative. Although, it would seem that it would be difficult to combine the lens hood borrowed from the “DSLRs” (so that the sun does not “dazzle” the lens) and the polarizing CPL filter (removes glare from the windshield plus removes the reflection in the glass of the panel and objects lying on it).

Datakam< /p>

In advance, please do not confuse - several manufacturers offer polarizing filters for their recorders. But these are only filters, without a hood. For example, "Brand No. 1" sells a "Polar" for 1,199 rubles.

In the area of ​​video-related features, we were extremely disappointed by the complete lack of fresh design ideas from competitors. For example, Datakam G5 can turn into a CCTV camera - the registrar in a special "stealth" mode stops showing any signs of work. But at the same time, he continues filming - it’s so easy to find out, say, how the car service workers want to “heat” you during the repair of your car.

For secretive drivers, we also have an on-the-fly video encryption mode. This means that it will be possible to view the video recorded by the recorder only on a computer through the proprietary DatakamPlayer player - and only after entering a password known only to you. It is very convenient if you need to prevent compromising evidence on you from falling into the wrong hands. Why such a seemingly obvious useful function is not in any other registrar is a mystery to us.

By the way, our proprietary player - DatakamPlayer - is the only player for files from registrars that exists in a version not only for Windows, but also for Mac OS. And if 99% of other programs supplied with recorders only allow you to view video, as well as GPS and accelerometer logs, then DatakamPlayer can also edit videos, save selected fragments with the quality of the original file. And the player also recognizes the connected memory card, Datakam recorder model, firmware version. And if there is a more up-to-date version, it offers to download it and automatically install

Russian electronics engineers honestly answer journalists and readers

Hello! With you are the engineers of the Russian Research and Production Association "Design Bureau Datacam" and personally the technical director of the enterprise - Vladislav Mekhantsev.

Not so long ago, an editorial was published on this site devoted to the analysis of the Datakam DVR and its comparison with three models of other popular brands.

Typically, registrar tests are selective and fairly typical surveys. We looked at the models externally, compared the buttons-menu-characteristics, half an hour on the road, examples of day-night video - and you're done.

Yes, our method of comparison has never occurred to anyone. Here we mean not so much journalists as our competitors, real manufacturers of registrars and, to a greater extent, numerous resellers of Chinese devices that flooded our market. Do you know why not a single company in Russia could still invite journalists to its production facilities? Yes, because in our country DVRs are assembled only here, in Datacam Design Bureau. There is simply nowhere for the rest to invite "sharks of the pen"!

However, what conclusions can be drawn from our comparison format? Most importantly, you get the opportunity to evaluate the manufacturer's approach to their devices, to the choice of components and the level of assembly. The fact that everyone has so far diligently avoided, without risking disassembling the pieces of iron. Alas, an ordinary journalist without special knowledge and explanations is unlikely to be able to independently evaluate this very assembly from a professional point of view. Therefore, we ourselves analyzed and immediately commented on what we saw, along the way answering a lot of questions (sometimes quite sharp).

Datakam< /p>

Our approach to the development and production of recorders is directly spelled out in one of the five principles of KB Datacam: "Any savings on components and reduction in the cost of materials during manufacture are prohibited."

With confidence, without undue modesty, we declare that we make cool, one of the best (if not the best!) home video recorders among all sold in Russia. And so we boldly decided to conduct such an analysis of devices to the screw.

You, dear readers, will object - a good product does not need advertising. Perhaps there are people in the world with telepathic abilities who receive all the information directly from space. Probably, such citizens already know about our company - NPO "KB Datakam", our registrars, who develops them and how, why they are fundamentally better than their analogues.

But instead of an illiterate person who speaks a different language, we get a savvy employee with a good technical education and a 100% complete understanding of the matter. Plus, we don’t have any “language barrier” with the Russians, which needs to be painfully overcome in the case of the Taiwanese-Chinese.

We also note that the import of components, rather than finished devices, reduces the cost of the registrar by 20% - we simply save on taxes. We save, we note, in a legal way! This allows KB Datacam to keep the prices of its devices almost at the pre-crisis level, although the price tags for components have almost doubled since the pre-crisis times.

In the near future, we will probably tell you more about how Datakam models are assembled in Russia. In the meantime - a small story from the reporters of the NTV channel:

“Brand No. 3 was chosen solely on the basis of price, combined with the similarity of characteristics, this is a fairly typical model for the Russian market.”

Let's say even more - the chosen "Brand No. 3" personifies the bulk of registrars on the shelves of large Russian retail chains. The very models that are completely (from designing boards to screwing screws into case parts) are created by Chinese developers (Samoon factory, for example). At best, they are slightly improved by order of domestic brands. In place of this sample could be almost any registrar of almost any umbrella brand. Umbrella - that is, a brand that does not specialize in registrars, but produces a wide variety of devices: from MP3 players to electronic photo frames and vacuum cleaners.

There are enough brands on the registrar market, under which many different models are produced, assembled at the same factories. Let's give a hint: if there are more than 3-4 models in the current brand line, and the assortment is updated more often 1-2 times a year, then you have 100% resellers gluing their nameplate to a Chinese product.

Datakam< /p>

We are by no means saying that this is bad - there is a buyer for every device. The same Brand No. 3 registrar costs only 5,540 rubles, which is almost 2.5 times cheaper than our Datakam G5. One of the goals of the analysis was to show how such savings are achieved and whether the consumer is really getting a bargain. Naturally, each consumer decides for himself what is more important to him. Or a guarantee of the reliability of the device, which will not delete important files and will not stop shooting at the most crucial moment. Or a lower price, without a full understanding of how it was achieved by the device manufacturer.

“Brand No. 2 is noticeably out of the ordinary because it has no screen and is focused on interaction with a smartphone. In addition, most of the premium offerings are for dash cams designed to replace the interior rearview mirror, and comparison with them would simply be incorrect.

Despite the lack of a screen, the Brand #2 recorder is still closer to classic portable models like the Brand #3 device and Datakam than top-end rear-view mirror recorders. That is why "Brand No. 2" was chosen. Plus, because this Korean brand is one of the most "fashionable" in the domestic registrar market. It was interesting for us to see how the products of Brand No. 2 look from the inside, and at the same time to compare the device with the brainchild of Russian engineers (that is, us) - Datakam G5. We ourselves were amazed by the reality, which we described in detail above - in fact, consumers are being offered the old model on four-year-old boards under a new name.

Datakam< /p>

Device Specifications

Let's give a table that, in our opinion, most correctly reflects the parameters of the registrars.

Users often wonder why our cutting-edge Datakam G5 uses the seemingly outdated Ambarella A5 processor and not the latest A7? To begin with, let us explain that A5 and A7 are the common names for the lines of “stones”. There are about a dozen versions of the Ambarella A7. For example, in the Brand No. 3 device, one of the “youngest” options, Ambarella A7LA30, is installed. Which in terms of performance is no better than the "stock" (that is, the stocks of which are still on the market for components in large quantities) the A5 series processor that we use in the Datakam G5.

However, it is worth recalling that KB Datacam is the only manufacturer of registrars in Russia and the CIS who has a direct contract with Ambarella not only for the supply of processors, but also for the development / improvement of software for them. Engineers from the USA and Russia have been and are engaged in “deep tuning” of Ambarella A5 for Datakam G5 together. And they do it so successfully that over time, the planned need for an immediate transition to the Ambarella A7 platform disappeared from KB Datacam. The record bitrate of 20 Mbit / s achieved by KB Datacams on the “five” was only repeated in Go *** cameras (sorry, the law “On Advertising” prohibits naming foreign brands), and even then due to the exclusive processor from Ambarella. Meanwhile, Datakam has a new record on the way - 30 Mbps. It will be installed in one of the upcoming registrars in 2015.

Datakam< /p>

Datakam G5 DUO - two cameras, record 30 Mbps, Ambarella LA85, Wi-Fi and Bluetooth. Look forward to autumn 2015!

Packaging and accessories

Datakam< /p>

Cable hooks, left to right - Brand #2, Brand #3, Datakam G5

And we did not save on the handbag, as our basic principles require. The accessory is made of natural suede, the main part is made of eco-leather, which is extremely difficult to get dirty. A similar accessory of "Brand No. 1" is entirely fabric, which is why it instantly collects dust and dirt.

Datakam< /p>

Dimensions and placement in the cabin

"If we look at power adapters, then the fact that G5 only has a detachable power cable.

This solution has an indisputable plus - if the driver touches the wire, then in the case of the Datakam G5, the cable will only fly out of the adapter connector.

Datakam< /p>

If the end of the cable is soldered to the inside of the block, as in the case of "Brand #1", "#2" and "#3", it is possible to completely tear the wire from the board right "with the roots". The durability of such a design, obviously, will be lower. And the risk of accidental damage to the accessory during operation is higher.

Literally in passing, the unique Datakam mount on neodymium magnets was mentioned in the material. From our point of view, it is worth dwelling on this feature of our devices in more detail.

This is really our author's development, its analogues simply do not exist yet. It is too expensive and difficult for Chinese factories to develop or even copy such a holder. It is on the basis of borrowing the idea with a magnetic holder that we will definitely be able to determine in the future when the Chinese will seriously take up the “cloning” of our device. The second similar “flag” will be copying our branded blend filter (see below for more on it).

We managed to create, perhaps, the only mount that is called a quick-release mount without reservation. Any other holders in registrars require certain manipulations to remove or install the camera.

“On the side of the “Korean” - maximum compactness, on the side of the “Russian” - great versatility, which is important for someone who, for example, acquires a registrar for the first time.

We would like to draw your attention to the fact that the device of the Korean "Brand No. 2" is the only one of the four recorders that is completely devoid of the ability to turn to the side. So, the driver generally does not have the opportunity to film what is happening to the left or right of the car, it is normal to capture a conversation with the inspector. The Datakam G5 mount allows you to almost instantly turn the camera sideways exactly 90 degrees or all 180 degrees at once. Brackets "Brand No. 1" and "No. 3" are based on a hinge, which allows you to quickly change the direction of the recording of the registrar. That is, these brackets are also definitely more effective than the Brand No. 2 fixed mount.

Behavior on the road, video

"Models from Datakam, Brands #1 and #3 greet you with their voice and turn on the screen."

At the same time, in our opinion, a more successful phrase is chosen in the Datakam G5: every time the registrar wishes the driver “Good luck!” and thereby sets the motorist in a positive way. The Taiwanese model is limited to the dry message "Welcome to the No. 1 Brand DVR."

“The result was slightly worse (compared to Datakam - approx.) by Brand No. 1. Despite the fact that the location of the camera turned out to be not very successful and the reflection in the windshield got into the lens, the distance when determining the number of an oncoming VAZ turned out to be only slightly less than that of the Datakam G5. Most likely, if you choose a better location, the result would be the same at all.

Especially so that readers can evaluate the quality of the image in a test 5-minute race, we put the source video files of Datakam, devices "Brand No. 1" and "No. 2" into free access. You can download the archive here. Remember that it is not worth evaluating the quality of videos on YouTube videos - the video service strongly compresses files in order to reduce their size. Therefore, we are not talking about demonstrating the original quality of the video. See only original files!

As you can see in our tests, which we conducted in the presence of journalists and bloggers, the registrars are almost in the best conditions - the bright sun is shining, almost complete cloudlessness. Occasionally, the leadership in the legibility of license plates of cars could change, mainly at short distances. However, in most cases, our Datakam G5 won. And this is not fake or advertising - the tests were carried out in the presence of journalists. Videos were also analyzed on the spot with the participation of media representatives.

The main problem of the Brand No. 1 device is the frequent frank blurring of license plates, when there is not even a chance to see the outlines of letters or numbers. And it is clearly seen that no matter how you choose a good installation angle on the windshield, you will not get the same result as the Datakam G5 for the Brand No. 1 model.

Datakam< /p>

Datakam< /p>

Datakam< /p>

We also want to dwell separately on such a Datakam G5 branded "chip" as a removable blend filter. The editorial talks about it, but we want to add more details.

Datakam< /p>

This hybrid accessory was created by our KB Datacam engineers. And no other manufacturer has yet offered even a remotely similar alternative. Although, it would seem that it would be difficult to combine the lens hood borrowed from the “DSLRs” (so that the sun does not “dazzle” the lens) and the polarizing CPL filter (removes glare from the windshield plus removes the reflection in the glass of the panel and objects lying on it).

Datakam< /p>

In advance, please do not confuse - several manufacturers offer polarizing filters for their recorders. But these are only filters, without a hood. For example, "Brand No. 1" sells a "Polar" for 1,199 rubles.

In the area of ​​video-related features, we were extremely disappointed by the complete lack of fresh design ideas from competitors. For example, Datakam G5 can turn into a CCTV camera - the registrar in a special "stealth" mode stops showing any signs of work. But at the same time, he continues filming - it’s so easy to find out, say, how the car service workers want to “heat” you during the repair of your car.

For secretive drivers, we also have an on-the-fly video encryption mode. This means that it will be possible to view the video recorded by the recorder only on a computer through the proprietary DatakamPlayer player - and only after entering a password known only to you. It is very convenient if you need to prevent compromising evidence on you from falling into the wrong hands. Why such a seemingly obvious useful function is not in any other registrar is a mystery to us.

By the way, our proprietary player - DatakamPlayer - is the only player for files from registrars that exists in a version not only for Windows, but also for Mac OS. And if 99% of other programs supplied with recorders only allow you to view video, as well as GPS and accelerometer logs, then DatakamPlayer can also edit videos, save selected fragments with the quality of the original file. And the player also recognizes the connected memory card, Datakam recorder model, firmware version. And if there is a more up-to-date version, it offers to download it and automatically install it

Russian electronics engineers honestly answer journalists and readers

Hello! With you are the engineers of the Russian Research and Production Association "Design Bureau Datacam" and personally the technical director of the enterprise - Vladislav Mekhantsev.

Datakam< /p>

Not so long ago, an editorial was published on this site devoted to the analysis of the Datakam DVR and its comparison with three models of other popular brands. We carefully read the opinion of a Mobile-Review.com journalist regarding our production, studied what readers wrote in the comments and decided to present our own view of the past event. In addition, in the first person, we will honestly answer the most tricky comments on the Mobile-Review.com material.

Yes, we place this material "as an advertisement", but solely for the purpose of expressing our own point of view here as a manufacturing company. We are an honest brand, and therefore we will not even try to disguise advertising as editorial material. (Especially since no one would have allowed to do this on Mobile-Review.com.) So those who categorically do not accept such a format can simply not read further - we do not impose our point of view on anyone.

Datakam< /p>

In the comments, readers primarily criticized us for the testing methodology. Like, what kind of comparison is this: we drove for 20 minutes in a car with registrars, and then dismantled the cameras to the screws. Night shooting is also needed!

For starters, let's say that the comparison made is by no means the basis for the final choice in favor of one or another model. We did not try to tell everything that is possible so that readers of the articles immediately after reading ran to buy one of the tested registrars. There are hundreds of methods for matching such devices. We have proposed only one method, which no one has implemented before us. The bottom line is to evaluate the level of the model based on the quality of the components and the thoroughness of the assembly. And the answer to the question why no one has done this before is obvious enough: for many brands in the registrar market, the result of opening their products can say little in their favor.

Shooting at night? Of course, for a full-fledged comparison of video quality, you need to record at night. And in two versions: with roadside lighting and without it. It would be necessary to compare the video at dusk, and also - in the rain, snow. And all these weather conditions would be worth shooting at night, and during the day, and at dusk. Each scenario without exception - both within the city and on the country road. There would be a huge comparison matrix in different lighting conditions, and such a test would be 100% objective. There is no limit to perfection, but conducting such a number of tests is expensive and unrealistic: you will have to spend a lot of time (your own and someone else's) and a mountain of money. Plus, there is no way we can force summer to suddenly turn into winter :) Among journalists, we have not yet met advocates of such thorough multi-week testing either. Typically, registrar tests are selective and fairly typical surveys. We looked at the models externally, compared the buttons-menu-characteristics, half an hour on the road, examples of day-night video - and you're done.

Yes, our method of comparison has never occurred to anyone. Here we mean not so much journalists as our competitors, real manufacturers of registrars and, to a greater extent, numerous resellers of Chinese devices that flooded our market. Do you know why not a single company in Russia could still invite journalists to its production facilities? Yes, because in our country DVRs are assembled only here, in Datacam Design Bureau. There is simply nowhere for the rest to invite "sharks of the pen"!

However, what conclusions can be drawn from our comparison format? Most importantly, you get the opportunity to evaluate the manufacturer's approach to their devices, to the choice of components and the level of assembly. The fact that everyone has so far diligently avoided, without risking disassembling the pieces of iron. Alas, an ordinary journalist without special knowledge and explanations is unlikely to be able to independently evaluate this very assembly from a professional point of view. Therefore, we ourselves analyzed and immediately commented on what we saw, along the way answering a lot of questions (sometimes quite sharp).

Datakam< /p>

Our approach to the development and production of recorders is directly spelled out in one of the five principles of KB Datacam: "Any savings on components and reduction in the cost of materials during manufacture are prohibited." We were really interested to know - how are things going with other manufacturers? First of all, two other representatives of the top segment, which offer the consumer very expensive devices. With the last budget participant in the comparison, everything was initially clear - the registrar turned out exactly for his little money. Such a typical Chinese product that can even record videos quite well and entices with sonorous characteristics on the box. But in reality, due to the specific approach to the work of both Chinese developers and Russian resellers, the buyer gets the opportunity to play the game “Will the registrar let me down at the most crucial moment?” and “How many months (or even weeks?) will the device last in real operating conditions?”.

With confidence, without undue modesty, we declare that we make cool, one of the best (if not the best!) home DVRs among all sold in Russia. And so we boldly decided to conduct such an analysis of devices to the screw.

You, dear readers, will object - a good product does not need advertising. Perhaps there are people in the world with telepathic abilities who receive all the information directly from space. Probably, such citizens already know about our company - NPO "KB Datakam", our registrars, who develops them and how, why they are fundamentally better than their analogues. But there is an opinion that there are very few such "experts-telepathists". We, the manufacturers of Datakam recorders, live in the real world. And therefore - yes, we use all kinds of information channels to "reach out" to the consumer and tell about what wonderful things we have been designing for the last three years. What we put our engineering mind, talent and soul into, all our seething creative energy.

And remember - if you categorically did not like our methodology with a comparative analysis of registrars, you can always read other materials, reviews on Datakam G5. Right on our website, we have collected almost fifty detailed articles from a variety of Internet resources in a separate list. In these articles, information is just given in the usual way: a button on the left is a button on the right, a connector on the left side of the case - another connector on the right side of the case, etc.
And, by the way, there are numerous examples of real video, taken by our camera.

Now let me give you a few, from our point of view, extremely important clarifications to the very editorial article of the Mobile-Review.com journalist. The process of comparing the registrars took about 6 hours - it is not surprising that the journalists could not fit many points into their extremely limited reports. We, in turn, did not interfere with the author's opinion of the portal - the journalist wrote about what he saw himself. And about what he himself considered necessary to write. Unfortunately, many key (in our opinion) points were not covered.

Datakam< /p>

In general, we decided to supplement the material as advertising. Precisely because I want to talk about many more important points, and it is unlikely that it will be possible to invite journalists on the same occasion a second time - they are busy people and not only write about registrars. This is not a "one-sided" dialogue - comments on our publication, as always, are open. Please, express your opinion about what you read and about our products in the comments.

In order not to confuse the reader, our material will follow the same structure as the original report on Mobile-Review.com, with quotes from it.

Datakam< /p>

As you understand, in this article we cannot directly call our competitors by their proper names - this would be a direct violation of the Advertising Law. So you have to get by with conventional names. Let's call the Taiwanese registrar in the orange box "Brand No. 1", the South Korean device without a screen - "Brand No. 2", and let the purebred Chinese from Russian resellers be "Brand No. 3". By the way, the top Korean "Brand No. 2" was added to the testing specifically "by request of readers." In the comments to articles about our first event, many people expressed their desire to see the insides of this particular device.

Positioning and principles for selecting devices for testing

"Datakam - device development - Russian office, assembly is now carried out in Taiwan."

Datakam recorders weren't just made in Taiwan. There was its own assembly shop "KB Datakam" with a capacity of up to 10,000 devices per month.

Of course, the employees themselves are Taiwanese, but all the processes were managed and monitored by three Russian process engineers who permanently resided in this Asian country. And by the time this material was published, we had moved the SKD assembly of Datakam recorders to Moscow. By the end of 2015, we plan to increase the degree of assembly localization of our devices to 70%. Due to the fact that we will “take away” part of the operations from foreign suppliers of components. At the same time, we will carry out the process of increasing the share of domestic assembly very carefully and gradually, so as not to lose quality in any case. After all, the country where the registrar gathers is secondary for the consumer. Primarily - the quality of the assembled device.

In the near future, we will probably tell you more about how Datakam models are assembled in Russia. In the meantime - a small story from the reporters of the NTV channel:

“Brand No. 3 was chosen solely on the basis of price, combined with the similarity of characteristics, this is a fairly typical model for the Russian market.”

Let's say even more - the chosen "Brand No. 3" personifies the bulk of registrars on the shelves of large Russian retail chains. The very models that are completely (from designing boards to screwing screws into case parts) are created by Chinese developers (Samoon factory, for example). At best, they are slightly improved by order of domestic brands. In place of this sample could be almost any registrar of almost any umbrella brand. Umbrella - that is, a brand that does not specialize in registrars, but produces a wide variety of devices: from MP3 players to electronic photo frames and vacuum cleaners.

There are enough brands on the registrar market, under which many different models are produced, assembled at the same factories. Let's give a hint: if there are more than 3-4 models in the current brand line, and the assortment is updated more often 1-2 times a year, then you have 100% resellers gluing their nameplate to a Chinese product.

Datakam< /p>

We are by no means saying that this is bad - there is a buyer for every device. The same Brand No. 3 registrar costs only 5,540 rubles, which is almost 2.5 times cheaper than our Datakam G5. One of the goals of the analysis was to show how such savings are achieved and whether the consumer is really getting a bargain. Naturally, each consumer decides for himself what is more important to him. Or a guarantee of the reliability of the device, which will not delete important files and will not stop shooting at the most crucial moment. Or a lower price, without a full understanding of how it was achieved by the device manufacturer.

“Brand No. 2 is noticeably out of the ordinary because it has no screen and is focused on interaction with a smartphone. In addition, most of the premium offerings are for dash cams designed to replace the interior rearview mirror, and comparison with them would simply be incorrect.

Despite the lack of a screen, the Brand #2 recorder is still closer to classic portable models like the Brand #3 device and Datakam than top-end rear-view mirror recorders. That is why "Brand No. 2" was chosen. Plus, because this Korean brand is one of the most "fashionable" in the domestic registrar market. It was interesting for us to see how the products of Brand No. 2 look from the inside, and at the same time to compare the device with the brainchild of Russian engineers (that is, us) - Datakam G5. We ourselves were amazed by the reality, which we described in detail above - in fact, consumers are being offered the old model on four-year-old boards under a new name.

Datakam< /p>

Device Specifications

Let's give a table that, in our opinion, most correctly reflects the parameters of the registrars.

Users often wonder why our cutting-edge Datakam G5 uses the seemingly outdated Ambarella A5 processor and not the latest A7? To begin with, let us explain that A5 and A7 are the common names for the lines of “stones”. There are about a dozen versions of the Ambarella A7. For example, in the Brand No. 3 device, one of the “youngest” options, Ambarella A7LA30, is installed. Which in terms of performance is no better than the "stock" (that is, the stocks of which are still on the market for components in large quantities) the A5 series processor that we use in the Datakam G5.

However, it is worth recalling that KB Datacam is the only manufacturer of registrars in Russia and the CIS who has a direct contract with Ambarella not only for the supply of processors, but also for the development / improvement of software for them. Engineers from the USA and Russia have been and are engaged in “deep tuning” of Ambarella A5 for Datakam G5 together. And they do it so successfully that over time, the planned need for an immediate transition to the Ambarella A7 platform disappeared from KB Datacam. The record bitrate of 20 Mbit / s achieved by KB Datacams on the “five” was only repeated in Go *** cameras (sorry, the law “On Advertising” prohibits naming foreign brands), and even then due to the exclusive processor from Ambarella. Meanwhile, Datakam has a new record on the way - 30 Mbps. It will be installed in one of the upcoming registrars in 2015.

Datakam< /p>

Datakam G5 DUO - two cameras, record 30 Mbps, Ambarella LA85, Wi-Fi and Bluetooth. Look forward to autumn 2015!

Packaging and accessories

“Brand No. 1 has a bundle that is not much inferior to the premium segment, although the box itself is simpler.”

Not that it was very critical, but we did not find a banal USB-microUSB cable in the package of the most expensive Brand No. 1 registrar. It's a shame that the manufacturer stinted on such an inexpensive, in fact, penny accessory. For example, Brand No. 2 took care of the user, a card reader is attached to the registrar.

Datakam< /p>

In our opinion, a responsible manufacturer should pay attention to the quality of not only the registrar itself, but also the accessories. From fastening to glass to hooks on which wiring stretches through the interior of the car. For example, hooks for laying cables in the cabin have the most modest dimensions in comparison with the options from the configurations of other registrars in the test. This is a natural consequence of using a thin power wire, so that during installation the cable can be put into any slot in the cabin.

Datakam< /p>

Cable hooks, left to right - Brand #2, Brand #3, Datakam G5

And we did not save on the handbag, as our basic principles require. The accessory is made of natural suede, the main part is made of eco-leather, which is extremely difficult to get dirty. A similar accessory of "Brand No. 1" is entirely fabric, which is why it instantly collects dust and dirt.

The durability of such a design, obviously, will be lower. And the risk of accidental damage to the accessory during operation is higher.

Datakam< /p>

By the way, since we've touched on the topic of "accidental grazing of cables", it would be nice to see what this situation will lead to at the point where the wires are attached to the recorders or holders. For example, for Brands No. 1 and No. 2 models, a plug inserted directly into the camera body is a risk of damaging not only the connector itself, but also the recorder board. For Brand No. 3, the decision to connect the cable to the bracket looks progressive. However, the suction cup is unable to provide a holding force comparable to 3M tape on glass. Therefore, if you pull the cable harder, there is a high probability that the mount, together with the recorder, will fall down.

Datakam< /p>

For the Datakam G5, the power cable is plugged into a steel core connector. The connector itself is in a holder made of solid durable plastic, it simply won’t be possible to damage anything here.

And the player also recognizes the connected memory card, Datakam recorder model, firmware version. And if there is a more up-to-date version, it offers to download it and automatically install it

Russian electronics engineers honestly answer journalists and readers

Hello! With you are the engineers of the Russian Research and Production Association "Design Bureau Datacam" and personally the technical director of the enterprise - Vladislav Mekhantsev.

Not so long ago, an editorial was published on this site devoted to the analysis of the Datakam DVR and its comparison with three models of other popular brands. We carefully read the opinion of a Mobile-Review.com journalist regarding our production, studied what readers wrote in the comments and decided to present our own view of the past event. In addition, in the first person, we will honestly answer the most tricky comments on the Mobile-Review.com material.

Shooting at night? Of course, for a full-fledged comparison of video quality, recording at night is also needed. And in two versions: with roadside lighting and without it. It would be necessary to compare the video at dusk, and also in the rain, snow. And all these weather conditions would be worth shooting at night, during the day, and at dusk. Each scenario without exception - both within the city and on the country road. There would be a huge comparison matrix in different lighting conditions, and such a test would be 100% objective. There is no limit to perfection, but conducting such a number of tests is expensive and unrealistic: you will have to spend a lot of time (your own and someone else's) and a mountain of money. Plus, there is no way we can force summer to suddenly turn into winter :) Among journalists, we have not yet met advocates of such thorough multi-week testing either. Typically, registrar tests are selective and fairly typical surveys. We looked at the models externally, compared the buttons-menu-characteristics, half an hour on the road, examples of day-night video - and you're done.

Yes, our method of comparison has never occurred to anyone. Here we mean not so much journalists as our competitors, real manufacturers of registrars and, to a greater extent, numerous resellers of Chinese devices that flooded our market. Do you know why not a single company in Russia could still invite journalists to its production facilities? Yes, because in our country DVRs are assembled only here, in Datacam Design Bureau. There is simply nowhere for the rest to invite "sharks of the pen"!

However, what conclusions can be drawn from our comparison format? Most importantly, you get the opportunity to evaluate the manufacturer's approach to their devices, to the choice of components and the level of assembly. The fact that everyone has so far diligently avoided, without risking disassembling the pieces of iron. Alas, an ordinary journalist without special knowledge and explanations is unlikely to be able to independently evaluate this very assembly from a professional point of view. Therefore, we ourselves analyzed and immediately commented on what we saw, along the way answering a lot of questions (sometimes quite sharp).

Our approach to the development and production of recorders is directly spelled out in one of the five principles of KB Datacam: "Any savings on components and reduction in the cost of materials during manufacture are prohibited." We were really interested to know - how are things going with other manufacturers? First of all, two other representatives of the top segment, which offer the consumer very expensive devices. With the last budget participant in the comparison, everything was initially clear - the registrar turned out exactly for his little money. Such a typical Chinese product that can even record videos quite well and entices with sonorous characteristics on the box. But in reality, due to the specific approach to the work of both Chinese developers and Russian resellers, the buyer gets the opportunity to play the game “Will the registrar let me down at the most crucial moment?” and “How many months (or even weeks?) will the device last in real operating conditions?”.

With confidence, without undue modesty, we declare that we make cool, one of the best (if not the best!) home DVRs among all sold in Russia. And so we boldly decided to conduct such an analysis of devices to the screw.

You, dear readers, will object - a good product does not need advertising. Perhaps there are people in the world with telepathic abilities who receive all the information directly from space. Probably, such citizens already know about our company - NPO "KB Datakam", our registrars, who develops them and how, why they are fundamentally better than their analogues. But there is an opinion that there are very few such "experts-telepathists". We, the manufacturers of Datakam recorders, live in the real world. And therefore - yes, we use all kinds of information channels to "reach out" to the consumer and tell about what wonderful things we have been designing for the last three years. What we put our engineering mind, talent and soul into, all our seething creative energy.

I would like to apologize to the readers for the quality of the registrars-opponents. Before the event, there was no “preparatory analysis” - we chose the models and, together with the journalists, saw for the first time what was inside the devices. And we are not to blame that our colleagues in the market have done a lot of obvious "jambs".

A side note - if you think Datakam recorders are very expensive, then... You are absolutely right! In the comments to an article about our analysis on a popular automotive site, one commentator furiously argued that registrars with a high price, in principle, were not needed by anyone. We quote: "The consumer will still give preference to the budget segment." True, a little later it turned out that the comrade himself drives an old Zhiguli for 60 (!) thousand rubles. Not surprisingly, he considers registrars worth almost a quarter of his car's price tag to be an unjustified luxury. Yes, we agree in advance with such consumers: our Datakam G5 will definitely not suit them. If translated into the language of smartphones, many consumers simply cannot afford Apple devices. But this does not mean that the world has converged on cheap Android-Chinese phones, and the Cupertino product is a whim and a whim of a handful of rich metropolitan majors.

And remember - if you categorically did not like our methodology with a comparative analysis of registrars, you can always read other materials, reviews on Datakam G5. Directly on our website, we have collected almost fifty detailed articles from a variety of Internet resources in a separate list. In these articles, the information is just given in the usual way: a button on the left - a button on the right, a connector on the left side of the case - another connector on the right side of the case, etc. And, by the way, there are numerous examples of real video shot by our device.

And now let me give you a few, from our point of view, extremely important clarifications to the very editorial article of the Mobile-Review.com journalist. The process of comparing the registrars took about 6 hours - it is not surprising that the journalists could not fit many points into their extremely limited reports. We, in turn, did not interfere with the author's opinion of the portal - the journalist wrote about what he saw himself. And about what he himself considered necessary to write. Unfortunately, many key (in our opinion) points were not covered.

In general, we decided to supplement the material as advertising. Precisely because I want to talk about many more important points, and it is unlikely that it will be possible to invite journalists on the same occasion a second time - they are busy people and not only write about registrars. This is not a "one-sided" dialogue - comments on our publication, as always, are open. Please, express your opinion about what you read and about our products in the comments.

In order not to confuse the reader, our material will follow the same structure as the original report on Mobile-Review.com, with quotes from it.

As you understand, in this article we cannot directly call our competitors by their proper names - this would be a direct violation of the Advertising Law. So you have to get by with conventional names. Let's call the Taiwanese registrar in the orange box "Brand No. 1", the South Korean device without a screen - "Brand No. 2", and let the purebred Chinese from Russian resellers be "Brand No. 3". By the way, the top Korean "Brand No. 2" was added to the testing specifically "by request of readers." In the comments to articles about our first event, many people expressed their desire to see the insides of this particular device.

Positioning and principles for selecting devices for testing

"Datakam - device development - Russian office, assembly is now carried out in Taiwan."

Datakam recorders weren't just made in Taiwan. There was its own assembly shop "KB Datakam" with a capacity of up to 10,000 devices per month.

Of course, the employees themselves are Taiwanese, but all the processes were managed and monitored by three Russian process engineers who permanently resided in this Asian country. And by the time this material was published, we had moved the SKD assembly of Datakam recorders to Moscow. By the end of 2015, we plan to increase the degree of assembly localization of our devices to 70%. Due to the fact that we will “take away” part of the operations from foreign suppliers of components. At the same time, we will carry out the process of increasing the share of domestic assembly very carefully and gradually, so as not to lose quality in any case. After all, the country where the registrar gathers is secondary for the consumer. Primarily - the quality of the assembled device.

The transfer of the assembly to Moscow was carried out both for patriotic (tired of working with the Chinese, who always strive to deceive and substitute, to be honest!), And for purely mercantile, economic reasons. The widespread belief that the Chinese are willing to work for pennies has long been a myth. A good qualified Taiwanese (Chinese) assembly line assembler values ​​himself at least $700 per month (about 40,000 rubles at the current exchange rate). In Russia wages are not lower. But instead of an illiterate person who speaks a different language, we get a savvy employee with a good technical education and a 100% complete understanding of the matter. Plus, we don’t have any “language barrier” with the Russians, which needs to be painfully overcome in the case of the Taiwanese-Chinese.

We also note that the import of components, rather than finished devices, reduces the cost of the registrar by 20% - we simply save on taxes. We save, we note, in a legal way! This allows KB Datacam to keep the prices of its devices almost at the pre-crisis level, although the price tags for components have almost doubled since the pre-crisis times.

In the near future, we will probably tell you more about how Datakam models are assembled in Russia. In the meantime - a small story from the reporters of the NTV channel:

“Brand No. 3 was chosen solely on the basis of price, combined with the similarity of characteristics, this is a fairly typical model for the Russian market.”

Let's say even more - the chosen "Brand No. 3" personifies the bulk of registrars on the shelves of large Russian retail chains. The very models that are completely (from designing boards to screwing screws into case parts) are created by Chinese developers (Samoon factory, for example). At best, they are slightly improved by order of domestic brands. In place of this sample could be almost any registrar of almost any umbrella brand. Umbrella - that is, a brand that does not specialize in registrars, but produces a variety of devices: from MP3 players to electronic photo frames and vacuum cleaners.

There are enough brands on the registrar market, under which many different models are produced, assembled at the same factories. Let's give a hint: if there are more than 3-4 models in the current brand line, and the assortment is updated more often 1-2 times a year, then you have 100% resellers gluing their nameplate to a Chinese product.

We are by no means saying that this is bad - there is a buyer for every device. The same Brand No. 3 registrar costs only 5,540 rubles, which is almost 2.5 times cheaper than our Datakam G5. One of the goals of the analysis was to show how such savings are achieved and whether the consumer is really getting a bargain. Naturally, each consumer decides for himself what is more important to him. Or a guarantee of the reliability of the device, which will not delete important files and will not stop shooting at the most crucial moment. Or a lower price, without a full understanding of how it was achieved by the device manufacturer.

“Brand No. 2 is noticeably out of the ordinary because it has no screen and is focused on interaction with a smartphone. In addition, most of the premium offerings are for dash cams designed to replace the interior rearview mirror, and comparison with them would simply be incorrect.

Despite the lack of a screen, the Brand #2 recorder is still closer to classic portable models like the Brand #3 device and Datakam than top-end rear-view mirror recorders. That is why "Brand No. 2" was chosen. Plus, because this Korean brand is one of the most "fashionable" in the domestic registrar market. It was interesting for us to see how the products of Brand No. 2 look from the inside, and at the same time to compare the device with the brainchild of Russian engineers (that is, us) - Datakam G5. We ourselves were amazed by the reality, which we described in detail above - in fact, consumers are being offered the old model on four-year-old boards under a new name.

Device Specifications

Let's give a table that, in our opinion, most correctly reflects the parameters of the registrars.

Users often wonder why our cutting-edge Datakam G5 uses the seemingly outdated Ambarella A5 processor and not the latest A7? To begin with, let us explain that A5 and A7 are the common names for the lines of “stones”. There are about a dozen versions of the Ambarella A7. For example, in the Brand No. 3 device, one of the “youngest” options, Ambarella A7LA30, is installed. Which in terms of performance is no better than the "stock" (that is, the stocks of which are still on the market for components in large quantities) the A5 series processor that we use in the Datakam G5.

However, it is worth recalling that KB Datacam is the only manufacturer of registrars in Russia and the CIS who has a direct contract with Ambarella not only for the supply of processors, but also for the development / improvement of software for them. Engineers from the USA and Russia have been and are engaged in “deep tuning” of Ambarella A5 for Datakam G5 together. And they do it so successfully that over time, the planned need for an immediate transition to the Ambarella A7 platform disappeared from KB Datacam. The record bitrate of 20 Mbit / s achieved by KB Datacams on the “five” was only repeated in Go *** cameras (sorry, the law “On Advertising” prohibits naming foreign brands), and even then due to the exclusive processor from Ambarella. Meanwhile, Datakam has a new record on the way - 30 Mbps. It will be installed in one of the upcoming registrars in 2015.

Datakam G5 DUO - two cameras, record 30 Mbps, Ambarella LA85, Wi-Fi and Bluetooth. Look forward to autumn 2015!

Packaging and accessories

“Brand No. 1 has a bundle that is not much inferior to the premium segment, although the box itself is simpler.”

Not that it was very critical, but we did not find a banal USB-microUSB cable in the package of the most expensive Brand No. 1 registrar. It's a shame that the manufacturer stinted on such an inexpensive, in fact, penny accessory. For example, Brand No. 2 took care of the user, a card reader is attached to the registrar.

In our opinion, a responsible manufacturer should pay attention to the quality of not only the registrar itself, but also the accessories. From fastening to glass to hooks on which wiring stretches through the interior of the car. For example, hooks for laying cables in the cabin have the most modest dimensions in comparison with the options from the configurations of other registrars in the test. This is a natural consequence of using a thin power wire, so that during installation the cable can be put into any slot in the cabin.

Cable hooks, left to right - Brand #2, Brand #3, Datakam G5

And we did not save on the handbag, as our basic principles require. The accessory is made of natural suede, the main part is made of eco-leather, which is extremely difficult to get dirty. A similar accessory of "Brand No. 1" is entirely fabric, which is why it instantly collects dust and dirt.

Dimensions and placement in the cabin

"If we look at the power adapters, the fact that only the G5 has an adapter that has a detachable power cable immediately attracts attention."

“If we consider power adapters, then the fact immediately attracts attention that only the G5 adapter has a detachable power cable.”

This solution has an indisputable plus - if the driver touches the wire, then in the case of the Datakam G5, the cable will only fly out of the adapter connector.

If the end of the cable is soldered to the inside of the block, as in the case of "Brand #1", "#2" and "#3", it is possible to completely tear the wire from the board right "with the roots". The durability of such a design, obviously, will be lower. And the risk of accidental damage to the accessory during operation is higher.

By the way, since we've touched on the topic of "accidental grazing of cables", it would be nice to see what this situation will lead to at the point where the wires are attached to the recorders or holders. For example, for Brands No. 1 and No. 2 models, a plug inserted directly into the camera body is a risk of damaging not only the connector itself, but also the recorder board. For Brand No. 3, the decision to connect the cable to the bracket looks progressive. However, the suction cup is unable to provide a holding force comparable to 3M tape on glass. Therefore, if you pull the cable harder, there is a high probability that the mount, together with the recorder, will fall down.

For the Datakam G5, the power cable is plugged into a steel core connector. The connector itself is in a holder made of solid durable plastic, it simply won’t be possible to damage anything here.

Literally in passing, the unique Datakam mount on neodymium magnets was mentioned in the material. From our point of view, it is worth dwelling on this feature of our devices in more detail.

This is really our author's development, its analogues simply do not exist yet. It is too expensive and difficult for Chinese factories to develop or even copy such a holder. It is on the basis of borrowing the idea with a magnetic holder that we will definitely be able to determine in the future when the Chinese will seriously take up the “cloning” of our device. The second similar "flag" will be copying our proprietary blend filter (see below for more on it).

We managed to create, perhaps, the only mount that is called quick release without reservation. Any other holders in registrars require certain manipulations to remove or install the camera.

“On the side of the “Korean” there is maximum compactness, on the side of the “Russian” there is great versatility, which is important for someone who, for example, purchases a registrar for the first time.”

We would like to draw your attention to the fact that the device of the Korean "Brand No. 2" is the only one of the four recorders that is completely devoid of the ability to turn to the side. So, the driver generally does not have the opportunity to film what is happening to the left or right of the car, it is normal to capture a conversation with the inspector. The Datakam G5 mount allows you to almost instantly turn the camera sideways exactly 90 degrees or all 180 degrees at once. Brackets "Brand No. 1" and "No. 3" are based on a hinge, which allows you to quickly change the direction of the recording of the registrar. That is, these brackets are also definitely more effective than the Brand No. 2 fixed mount.

Behavior on the road, video

"Models from Datakam, Brands #1 and #3 greet you with their voice and turn on the screen."

At the same time, in our opinion, a more successful phrase is chosen in the Datakam G5: every time the registrar wishes the driver “Good luck!” and thereby sets the motorist in a positive way. The Taiwanese model is limited to the dry message "Welcome to the No. 1 Brand DVR."

“The result was slightly worse (compared to Datakam - approx.) by Brand No. 1. Despite the fact that the location of the camera turned out to be not very successful and the reflection in the windshield got into the lens, the distance when determining the number of an oncoming VAZ turned out to be only slightly less than that of the Datakam G5. Most likely, if you choose a better location, the result would be the same at all.

Especially so that readers can evaluate the quality of the image in a test 5-minute race, we put the source video files of Datakam, devices "Brand No. 1" and "No. 2" into free access. You can download the archive here. Remember that it is not worth evaluating the quality of videos on YouTube videos - the video service strongly compresses files in order to reduce their size. Therefore, we are not talking about demonstrating the original quality of the video. See only original files!

As you can see in our tests, which we conducted in the presence of journalists and bloggers, the registrars are almost in the best conditions - the bright sun is shining, almost complete cloudlessness. Occasionally, the leadership in the legibility of license plates of cars could change, mainly at short distances. However, in most cases, our Datakam G5 won. And this is not fake or advertising - the tests were carried out in the presence of journalists. Videos were also analyzed on the spot with the participation of media representatives.

The main problem of the Brand No. 1 device is the frequent frank blurring of license plates, when there is not even a chance to see the outlines of letters or numbers. And it is clearly seen that no matter how you choose a good installation angle on the windshield, you will not get the same result as the Datakam G5 for the Brand No. 1 model.

We also want to dwell separately on such a Datakam G5 branded "chip" as a removable blend filter. The editorial talks about it, but we want to add more details.

This hybrid accessory was created by our KB Datacam engineers. And no other manufacturer has yet offered even a remotely similar alternative. Although, it would seem that it would be difficult to combine the lens hood borrowed from the “DSLRs” (so that the sun does not “dazzle” the lens) and the polarizing CPL filter (removes glare from the windshield plus removes the reflection in the glass of the panel and objects lying on it).

In advance, please do not confuse - several manufacturers offer polarizing filters for their recorders. But these are only filters, without a hood. For example, "Brand No. 1" sells "Polar" for 1,199 rubles.

In the area of ​​video-related features, we were extremely disappointed by the complete lack of fresh design ideas from competitors. For example, Datakam G5 can turn into a CCTV camera - the registrar in a special "stealth" mode stops showing any signs of work. But at the same time, he continues filming - it’s so easy to find out, say, how the car service workers want to “heat” you during the repair of your car.

For secretive drivers, we also have an on-the-fly video encryption mode. This means that it will be possible to view the video recorded by the recorder only on a computer through the proprietary DatakamPlayer player - and only after entering a password known only to you. It is very convenient if you need to prevent compromising evidence on you from falling into the wrong hands. Why such a seemingly obvious useful function is not in any other registrar is a mystery to us.

By the way, our proprietary player - DatakamPlayer - is the only player for files from registrars that exists in a version not only for Windows, but also for Mac OS. And if 99% of other programs supplied with recorders only allow you to view video, as well as GPS and accelerometer logs, then DatakamPlayer can also edit videos, save selected fragments with the quality of the original file. And the player also recognizes the connected memory card, Datakam recorder model, firmware version. And if there is a more up-to-date version, it offers to download it and automatically install
