I keep my NVR and cameras on a stand alone network. My Dahua 4216 16 PoE port NVR NIC is 192.168.2.108 with gateway 192.168.2.1. The NVR is connected to a 4G wireless modem/router.
Several Dahua cameras are connected directly into the PoE ports and the NVR automatically assigned them IPs in the 10.1.1.x range on ports 1, 2,3 etc. They all work fine.
Two other Dahua cameras are connected into a PoE switch 100m away and the switch is connected into the modem/router (via a wireless bridge just in case that matters). The camera list on the NVR's monitor shows these two cameras have unique IPs in the 192.168.2.x range on port 37777. I guess the router allocated these IPs. These work fine. One small issue is that several times a day I get a "CAM Offline Alarm" with these two cameras.
Two questions:
(1) is it acceptable for the NVR and its two switched cameras to have a different IP sub net to the other PoE connected cameras (192.168.2.x and 10.1.1.x) ?
(2) is it possible that the different sub nets are causing the CAM Offline Alarm in the two switched cameras 100m away?
