Multicast can be used to pull up live view when the number of connecting Web clients exceeds the limit the NVR can accommodate.
1. Click System -> Network -> Multicast.
2. 2. Select the check box to enable multicast, and then enter the multicast IP and port number.
3. Click Apply to save the settings.
4. Log in to the Web client and set Live View Protocol to Multicast under Setup -> Client.
Note
Set the multicast IP correctly. Multicast address is class D address with the range 224.0.0.0 through 239.255.255.255
