12V Car Auto Rear View Camera Voltage Signal Ballast Ripple Splash Screen Interferenc Power Filter

Installation instruction
Output positive and negative power supply connected to the camera, reversing lights power input connector is negative, reversing ballast is the solution to your reversing camera interference ripple best choice

Notice
Some models of German cars and American cars are, after engine start, output voltage interferences, power supply to the reversing lights are not pure DC power supply, but a pulse signal is superimposed on top oscilloscope can be used to test if the conditions will It found a similar square wave signal. Camera power supply line directly on the down lights, because the working voltage is very unstable cause the camera does not work properly, the video signal output is also not normal, so the host can see there is a severe interference, jitter, or not to switch reversing the screen
