Cams worked fine for about two weeks, then no signal. can't get camera's to work. flood light activation works fine day or night.
It would be hard to believe two cams could fail at the same time. My 1st step would be check to make sure the receiver has power and that it's antenna is directed towards the floodcams. check all video connectors.
maybe a cat/dog (if you have one) has chewed the wires! Or your receiver power supply has failed!
