I am looking at adding a POE Switch. The NVR is on a 192.168. network but the cameras plugged into the NVR want to be on a 10.1. Two new cameras came as 192.168 and the NVR could not find video stream. I had to change to 10.1 So if I connect the switch to the router that is on a 192.168 do I change the cameras back to 192.168 ip address and will the NVR find them? I hope I am explaining this right.
