I disassemble the camera from the Research Center “Technology” myself
Finally my camera arrived – a two-megapixel mini dome 360+1 2MDIS-28, manufactured, as it says on the sticker, in Krasnodar. By the way, on manufacturer’s website I didn’t find such a model, as well as in the REP registry, but there is a camera there very similar. I understand that the registry chamber can differ quite significantly in terms of filling, but, as I already mentioned in the previous analysis of SIC — it’s incredibly difficult for a private person to buy their camera, so there was no need to choose what to disassemble.
But let’s talk about everything in order – let’s analyze the filling, the software, and at the end we will draw conclusions.
The hardware of the IP camera of the Scientific Research Center “Technology”
It was not possible to immediately identify the body – some kind of mixture of Hika and rhinoceros, write in the comments if you know who produces them.
The camera is mounted on a removable rotating platform – a very strange solution for dome cameras, which are supposed to be vandal-proof.
We see a lot of Quality Control Department stickers in Russian (and literally all the free space is covered with these stickers), as well as a sticker with very detailed information, including the production address: Russia, Krasnodar.
The cables have been “translated” into Russian. The reset button is located in the rear, which is also very questionable for vandal-proof cameras. By the way, it’s already on YouTube detailed review of a similar camera, which discusses ergonomics and engineering solutions from the installer’s point of view – I think the author there is more competent in the assessment. We will focus on studying the import-substituting nature of the camera 🙂
The body is tightly knit, one might even say it’s made of leather, suggesting Russian manufacture. If it had been milled from a single piece of aluminum, then most likely it would have been so 🙂 Well, most likely China.
On one of the frame screws we see another quality control mark and a seal (with the date of manufacture?) – also in Russian. Well, that is, at least the Research Center “Technology” forced the Chinese to sculpt stickers in Russian inside the camera 🙂 The camera is not new – it’s early 22 years old.
Those same terrible glued connectors that Maxim mentioned in the previous article. Honestly, at that moment I realized that I had made a mistake when I decided to study the camera from the hardware – I was afraid that I would no longer be able to put it back together without soldering.
Inside there were three boards: backlight, motherboard/sensor and power board.
Let’s start with the sensor board/matboard. As already mentioned by Maxim, the circuit is single-board and gets quite hot, as I later became convinced of: after an hour of work on the dome it was 50 degrees, it was noticeably hot in the hand. Judging by the markings of BV-M06 3350M-V2, this is still the same board based on SigmaStar SSC337DE as in Maxim’s review. The BV marking apparently denotes the manufacturer, Brovotech, although I won’t say so, since the Chinese have a lot of similar modules, but I couldn’t find a specific one. If you know what this is, I will be glad to see the link in the comments.
But with the power board everything is much more interesting. Firstly, it is assembled on a massive transformer and ceramic capacitors, which I have never seen from the Chinese. And secondly, the gas arresters are obviously striking; they are probably too powerful for protection against breakdowns, so most likely it is something like lightning protection.
Pay attention to the markings for components, which are not typical for the Chinese, as well as the silk-screen printing of the Research Center “Technology”. I would venture to guess that the power board was actually developed in Russia. Where the board is assembled is a big question, but the likelihood of a domestic development, in my opinion, is high. On SIC website there is no data on board soldering, only vague “Russian production”.
Well, the last board – the backlight – has all the same features of the arrangement of components and board markings, which also indicates its probable domestic development.
I don’t think there’s anything incredible here; even I can assemble several diodes in series 🙂
Traces of domestic development are present, which is good news. However, as I said in the article about Si-Cam, the main and main module is the processor board and sensor, and they are clearly not of our production. I repeat, this is not a register camera, they refused to sell it to me, maybe everything in it is different and Elbrus is worth it – who knows…
Fly in the ointment
I got a camera with the same “stable” firmware as Maxim. In his review, he tactfully kept silent about the fact that it is Chinese, but we see this literally on the very first tab of the web interface.
.
To be honest, there is nothing special to dissect further, but I will add that the MAC address of the camera is also Chinese, from an incomprehensible pool.
If it were possible to touch that same Nexus from the domestic software registry, I’m sure the result would be more encouraging. Representatives of the Research Center “Technology”, in case you read the article, I don’t want to seem like a beggar, but send me a registry camera with domestic software for review, I’m even ready to buy it for my own money if you feel sorry 🙂
conclusions
Let’s summarize: a case of unknown, probably Chinese origin, a Chinese video module, Chinese firmware, a domestic power board, a domestic backlight, probably a domestic assembly – that’s already something. To design any modules, a design bureau is required, that is, a certain material and technical base and competent engineers. In this case, I see no reason why not to design processor boards or sensor boards yourself.
On the NIC channel there is production videobut I believe in beautiful videos last of all, although on the other hand I don’t see any problems in organizing a screwdriver assembly from ready-made modules made in China, but, for example, designed in Russia.
In any case, I invite representatives of the Research Center “Technology” to dialogue: I would be glad to see drawings or technological documentation. And if possible – without threats of lawsuits 🙂
This is how the review came out: neither fish nor fowl. I wasn’t even sure that it was worth writing it with such a texture, however, since there is a Russian manufacturer, then we should consider it. I hope the article entertained at least someone, write in the comments who else you would like to see at the “autopsy”.
