User's Manual - 39
1. Cameras and the NVR must reside in the same subnet. Otherwise, the NVR will not be able
to recruit them into a recording configuration.
2. It is recommended all network cameras use static IPs. If you let a DHCP server assign IPs to
these cameras, IPs may be changed later and the NVR may not recognize them.
NOTE:
If preferred, change the language of UI text using the Language shortcut on the desktop.
