Night Vision Problems in General Analog CCTV Discussion Posted June 18, 2019 I noticed that on a rainy night just after midnight to a few minutes after 6:00 am that 3 of the 6 cameras on the CCTV system stopped showing and recording however they work fine in the daylight. One of the functioning ones was grainy and showing intermittently. I have identified the offending camera. When I turn on the lights that camera along with the others are functioning. When I disconnected that camera, the others are working fine with night vision. I am wondering why the issue with the problem camera is affecting the other cameras on the network. Does anyone have any idea what could have caused this problem?
