Anyone who has installed a wireless backup camera system , then finds that the monitor is flickering and driving you nuts, there is a solution. First look at the receiver (RX) or the transmiter (TX) if you see 2.4 GHZ here is your problem, the frequency 2.4 is used by just about everything now even your bluetooth. When the RX picks up the video signal from the camera it turns on the monitor, but with all the equipment running at the same frequency the RX is just at the threshold and starts to turn on the monitor.The solution, is to only power the RX when the vehicle is in reverse, yes it isn't wireless anymore. You need to run a wire from the backup lights 12 volts to the RX. It would be nice to find some kind of wireless switch that would turn on the RX only when the car is in reverse.
