I have a V5.2.5 build 141201 NVR from HIKVISION with 8 POE ports. I have 4 cameras on ports 1-4 which are all DS-2CD2332-I and everything works. I recently purchased a DS-2CD2335-I and when I plug it into port 5,6,7, or 8 nothing happens. However, if I unplug an existing camera in port 1,2,3, or 4 and plug the new camera in it hooks up fine. Any ideas?
