I have 4 cameras on my system and one of them is having problems with the infrared night vision. The red LED lights did not come on which meant there was no night vision. I powered off the cameras (they are all connected to one plug) and then powered them on again and the faulty camera's LED lights came on and the night vision was working. It worked for about 2 weeks then the infrared night vision stopped working again, so I did the same thing (powering off the cameras) and the night vision was working again. It then happened again for a third time and again I got the night vision working. Does anyone have any idea why this is happening and what I can do to stop it happening again?
