Wireless Rear View Car Camera

Hello, Muscovites! Today I’ll tell you about a gadget useful for motorists, namely, a rear view camera. Yes, not simple, but with wireless transmission. Perhaps many owners of large cars have faced the problem of rear parking, especially if there is no parking sensors and other similar smart electronics. Such a simple camera with a CCD matrix is ​​just designed for such cases.
I ask for details under cat. Attention, a lot of photos.
I must say right away that I did not order, but my colleaguework. Recently, he became the owner of a large car and decided to buy a similar device in order to preserve unnecessary nerves during parking, and the car itself in the basic configuration is not equipped with anything like that. During the search for aliexpress, I came across such an option, which it was decided to order. The seller’s description said that the camera is suitable for the following types of vehicles: “Nissan Sunny Pathfinder qashqai patrol, X-TRAIL Citroen C4 C5 Peugeot 408 508”, which was necessary (it has a nissan qashqai). The peculiarity of this camera is that it comes with a plastic cap for the room illumination lamp. And since these caps, as I understand it, differ from different manufacturers, so the camera is suitable for a limited number of car models. But if you look at this seller, you will find similar cameras for other brands.
The parcel arrived quickly, after a week and a half already lay at the Belarusian customs. Photo Box:
Open the cardboard box:
Contents of delivery:Includes: camera with wires, transmitter, receiver, instructions.
Now proceed to a more detailed discussion. Detailed photographs of the components were taken at work on the phone, so I apologize in advance for the quality. I’ll start right away with the instructions, since it contains technical specifications. Most are written in Chinese, but the main parameters are in English: The characteristics of this model in the center. Walk through the main points. CCD matrix. Viewing angle of 170 degrees. Resolution 520 TV lines. Looking at the picture that the camera makes, I’ll say for sure that it doesn’t smell like five hundred here. It all depends on the specific matrix and manufacturer, but here the number is indicated ideally, and how much is actually difficult to determine. I did not engage in such a laborious task.
Minimum Lighting 0.1 lux, when the LEDs are on (yes, the camera is equipped with LEDs for nighttime operation), this value decreases to 0.01. As you later will see for yourself, here the Chinese seem to have not lied. The camera has automatic white balance and gain. Protection IP67-68. Why I do not know through a hyphen, but the camera looks hermetic, moisture should not get there. Well, the voltage is 12V. With the other parameters, specialists will figure it out without problems, and ordinary people most likely will not need them.
Other photos of the instruction

Let's take a closer look at the camera with a plastic cap:It is bolted to the cap in whichthere will be a number illumination lamp. The cap is put in place of the standard one, the only nuance is to put a light bulb in there later. The photo shows that a protective film was glued on the glass above the optics. Near the corners are 4 LED night lights. The sticker on top says that there is a matrix inside the CCD. A wire comes out from the back of the camera, which ends with two connectors (one power, the other video). Wire length 50 cm. They are connected to the corresponding transmitter sockets. Video is transmitted through a standard tulip.If you believe the inscription on it, then the transmission is carried out at a frequency of 2.4 GHz. The second cable coming from the transmitter ends with 2 power wires, black and red. Wire length 120 cm.
And here ATTENTION: the manufacturer messed up with the color of the wires, or rather they were simply confused: the black wire is not standard ground, but "+", and red, on the contrary, is "-" !!! For such a mistake, the engineer or assembler who did this should be fired, or better both. Fortunately, the camera most likely has protection against polarity reversal. Therefore, during the test run it did not burn out. Actually, during this connection this error was detected.
These wires should be connected inside the trunk torelevant places. Plus it connects to the power of the reversing lamp. This is due to the specifics of turning on the camera (read about this at the end of the review). The minus should go to the common ground bolt, but because unscrewing it was a problem without a good screwdriver, so my colleague just connected the earth in parallel to the negative of the lamp.
Well, we still have a receiver:Everything is simple here: an antenna and two wires: power and video to an external source, which can serve as a tablet or navigator. On the reverse side is the same mini USB into which we will connect the cable from the navigator kit and insert it into the cigarette lighter.
Let’s look atpicture quality indoors. I took screenshots by connecting the receiver to the computer's video capture card and powered from a stationary power source. The camera with the transmitter was located behind a concrete wall. I will post screenshots under the spoiler, as photos already and so on.
Testing the camera indoors

Transmission range is excellent. We tested the maximum distance taking into account obstacles. It came out approximately 8-9 meters through 2 concrete walls. A solid result.
It remains only to see how the camera looks attached to the car and how the receiving part connected to the navigator looks in the cabin.
Under the protrusion on the trunk, the camera is not very visible,and if she stands back to the roadway, then all the more so she is unlikely to be seen by any bully. But still, the camera is noticeable and if the bully sets out to find her, he will find it and can damage it. Therefore, put at your own peril and risk.
Let's see how the receiving part is mounted in the cabin(on the example of my colleague). By the way, to display the picture, he bought the Prestigio GeoVision 5800 BTHDDVR navigator. In our country (Belarus) this costs from 80 to 100 cu in online stores Another photo, including with the camera turned on, under the spoiler:
Photos inside the cabin

Now about how, in fact, turns oncamera. In normal mode, the navigator displays its data. When the driver engages a reverse gear and starts to move backward, then a voltage is applied to the camera from the back light of the vehicle, which starts transmitting the image. As soon as the reverse gear is off, its operating information will be displayed again on the navigator. You can see how it works in this short video:

It turns on and turns onreverse gear disengagement (ACP), accompanied by turning on / off the camera. A distinctive feature of this camera is that it shows a “live” picture, that is, it mirrors the image from left to right, and you see which side you really need to turn the steering wheel (that is, if the obstacle is on the screen on the right, then turn the steering wheel need to the left).
What I want to say in conclusion. The camera is definitely worth the money. In my opinion, this is a small price for a wireless parking assistant. The only serious minus that I wrote about was that they mixed up the power wiring, which could lead to camera breakage. But it most likely turned out to be protection against polarity reversal. Therefore, check the contacts in any case with a tester. Well, and, of course, it will be noticeable in any case, it can hurt. But my colleague has not complained so far, there have been no incidents.
