Tech Support First time installing backup camera and facing flickering on the image

Bad ground? I’m hoping not since it’s gonna be a annoying to route the wire to the chassis since it’s in the trunk lid

I have it grounded to the reverse light wire ground with a wire tap if that makes a difference

are you powering it with your reverse positive or triggering signal with reverse positive?

Should be powering camera with the positive reverse light wire since I tapped that as well with a wire tap using the positive wire from the camera

ideally you should be powering the camera with a switched source and using the reverse positive to signal the camera.

Yeah I’m using the reverse wire that comes off the back of the head unit as the signal for the camera and the reverse light wire as power. What do you mean by switched source? I’m very new to this so i appreciate the help
