Network
On the Network tabbed window, you can configure the network type, IP address, and the
connection ports for video streaming.
You can select DHCP as the method for cameras to acquire IP addresses, or you can manually
configure static IPs for a single or all cameras. Using static IPs is recommended. Although
the NVR can remember the MAC addresses of cameras, if IPs are changed under the DHCP
configuration, your NVR may still fail to connect the cameras. Please consult your network
administrator for details about network settings.
It is usually not necessary to change port numbers for the HTTP and RTSP ports unless there is
a conflict in your network environment.
