6. Click OK to save and exit menu.
Note:
Time synchronization interval has a range of 0-10080ms, normally 7200ms. 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.
Configuring a Remote Alarm Host
With a remote alarm host set, the DVR will send a signal to the host when an alarm is triggered. The remote alarm host
must have the Network Video Surveillance software installed.
To set up a remote alarm host:
1. Enter Network settings menu by clicking Menu > Setting > Network.
2. Select the Advanced tab.
3. Click the Set butt next to Host/Others to enter the Host/Others menu, as shown in Figure 9.

4. Enter Alarm Host IP and Alarm Host Port . Alarm Host IP is the IP of the remote PC which has the
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 suggested that the IP address range of
239.252.0.0 to 239.255.255.255 be used.
To set up multicasting:
1. Enter the Network Settings menu by clicking Menu > Setting > Network.
