Reverse camera disruptions - The reversing camera flashes as you turn on the rev

Question

Welcome, I bought a car mirror in China with Android 5.0 (adapted to the device) and 3G with such: a2g0s.9042311.0.0.JZMyd3 After connecting, everything is ok until I do not turn on the reverse. The following video shows how the mirror behaves. First seconds of the movie - reverse turned on...

Hello.
My suggestion is that the power supply of the reversing camera, after turning on the reversing light, was switched on via the relay from the fuse box. For understanding, connect the reversing camera's power supply, through the relay contacts, to this your fuse box, and the relay coil with one lead to the ground and the other to the reversing light. When the voltage is applied to the reversing light, the relay will switch on and the voltage will be applied to the reversing camera via shorted contacts.

Emil, what would you recommend the relay? I mean parameters. I found on allegro: CAR RELAY + SOCKET 5 PIN 561 12V 40A and CAR RELAY WITH FUSE 12V 30A

It should be. The Chinese pretend to give you room for maneuver and the menu on the right blinks by the way.

emil · Answer

All you need is a small 12V relay coil with a 2A contact load. These relays what you gave are a lot oversized both in size and load of contacts.

I close the topic, helped the relay and connecting the camera to an additional source, as my colleague wrote !!

Another problem appeared

Due to the fact that the reversing camera cable was too short and I could not attach the camera to the target place (under the license plate) I decided to extend the cord. I did this and now the image after switching on the backlight glows like in the attached picture (in green). The cable I made it is unshielded, I do not know if it can affect ... or maybe the cable length is not adjusted to the set?
Please, suggest what to do to be ok, what cable to extend it. The original cable comes out with 5 wires and all are wrapped with aluminum foil (I was looking for such a cable but I do not know where to buy).

Thanks for the info. I know where to buy the cable, now I need information or if I buy a cable, will it help and the screen will display normally ??

I do not really understand the comment in red from the moderator. My idea that the camera does not work was just a cable fault but I'm not an expert.
I do not want to go into costs.
If it is certain that it will help me, I have found a cable like this:
https://www.tme.eu/pl/details/liycy-5x0.5/przewody-wielozylowe-ekranowane/lapp-kabel/0034605/
5 veins + screen and now the question is, will it be ok?
My original has 5 veins (photo attached below).
The new screen is slightly different (with tinned copper wires) and in the old one with such aluminum foil. I do not know if this is a difference?

CameR · Answer

6.84 PLN / 1m are costs? Who is supposed to check it? Looking at your last photo, your soldered cable is not the best. It does not matter. It is important that you permanently connect the screen of the old cable with the screen of the new cable.

Hello, I assembled the camera today and it works fine but you have to connect through the relay. I bought some from vw 30 and I hooked up and nothing jumps.
