I have a Hikvision DS-7608 NI E2/8P NVR with DS-2CD2332-I cameras. The system has been running for 3 years with no issues. All of a sudden one of the cameras has stopped working. When I reboot the system or pull the POE plug out and put back in the camera starts working again but if I come back an hour later it has stopped working?? Any ideas??
