6. Click OK to save settings and exit the NTP Settings menu.
Note:
Time synchronization interval has a range of 0-10080 min, normally 7200 min. If the DVR is used on a public
network, you should use a NTP server that has a time synchronization function, such as the server at the National Time
Center (IP Address: 210.72.145.44). If the DVR is setup in a more customized network, NTP software can be used to
establish a NTP server used for time synchronization.

Network Video Surveillance software installed. The Alarm Host Port must be the same as software’s
alarm monitor port (default port is 7200).
Configuring Multicast
Setting up multicasting solves limitation issues when streaming videos through a network access device. A multicast
address spans the Class-D IP range of 224.0.0.0 to 239.255.255.255. It is recommended to use the IP address range
from 239.252.0.0 to 239.255.255.255.
To set up multicast:
1. Click Menu > Settings > Network to enter the Network Settings menu.
2. Select the Advanced tab.
3. Click the Set button next to Host/Others to enter the Host/Others menu.
