Thanks,
Not sure what was going on, but an nmap scan couldn't see any cameras. So I ended going through the config of each camera, manually reassigning IP addresses from scratch, now all reconnected to the PoE ports on the NVR and working as previously.
Fingers crossed it stays like that :)
As the title says, overnight, I have lost the connection to all 4 of my POE cameras (one PTZ, one turret and 2 dome) via my NVR.
All 4 cameras were plugged into the POE ports of the NVR, and Status now shows Offline(Network is unreachable)
If I plug the cameras into a sperate POE switch, I am...
Just set up a DS-7608NI-I2/8P NVR with a new DS-2DE4A225IW-DE PTZ camera.
I've seen this mentioned elsewhere in the forum, but no-one has given a proper answer.
