I have one camera that's not directly connected to the NVR (HIKvision doorbell camera, which won't work right unless you connect indirectly to the NVR as if it's a stand-alone). Anyway, I obviously have to set the IP address in the NVR as what it is on the network. It saves and works fine, but every time I reboot the NVR, it changes the IP address to one that's been assigned by the NVR's DHCP. Then, I get the red X in the camera list. Have to go in and change the IP address again.
