Multicast
Multicast is a transmission mode for data packets. When there are multiple hosts to receive the
same data packets, multiple cast is the best option for reducing the bandwidth and the CPU
load. The source host can send out just one data for transit. This function also depends on the
relationship of the group member and the router group.
1. Click Multicast under NETWORK to open the Multicast configuration interface.

2. Select Enable to enable multicast.
3. Enter a multicast IP address in the IP Address box. The address must be valid for
multicasting and should be in the range 224.0.0.0 to 239.255.255.255 for IPv4 or have the
prefix ff00::/8. An address in the range 239.252.0.0 to 239.255.255.255 is recommended.
4. Enter a multicast port number in the Port box, or use the default setting (36666).
5. Click Apply to save your settings.
6. Click OK to exit the Setting menu.
Auto-Registration
Auto Register allows the device to automatically register to the proxy you have specified. This
allows you to use the client-end to access the NVR through the proxy. The proxy acts as a
switch. In network service, the device supports IPv4 server addresses or domains.
1. Click Auto Register under NETWORK to open the Auto Register configuration interface.
