1PC Car back-up image f screen interference ballast filter rear-view camera universal

Warm reminder: display device please do not shoot, incompatible. Non-german or American cars please , French cars Citroen does not support, because the current signal of different cars is different, non- signal interference, the use of this rectifier is invalid! ( please shoot our relay, it can be solved)

Perfect solution to the problem of interference in Volkswagen cars.

Cause of fai:

Some models of German and American cars, after the engine starts, the output voltage interference is larger, the power supply to the re lamp is not pure DC power supply, but rimposed a signal on the above, if there are conditions available oscilloscope test, it will be found to be a similar square wave signal. The camera power supply line is directly on the re lamp, because the working voltage is extremely unstable, the camera is not working normally, and the output video signal is not normal, so what you see on the host is serious interference, shake, or do not switch the re screen.
