Some of clients must met problem as the below description shows before, the camera is powered from the drivers side reverse light, checked with a multimeter. But when put the car in reverse, the camera comes on, looks great, then within 5-10 seconds it begins to flicker and goes to black screen and display NO SIGNAL or even return back to the main menu, just as the following video shows:

What is happenning? Why is that? After our efforts on some tests, we found out that is because the camera's main power directly from the reverse light. That won't work. There may be a constant 12V but there isn't enough current to keep it on. That's why it cuts off after a short while. You need to use a relay switch. The backup up light will turn the relay switch on and the main power will come from the battery.
Here is an instruction video for that, you may check to solve your issue, hope this will help!
