3. Configure the following NTP settings:
• Interval: Time interval between the two synchronizing actions with NTP server. The unit is minute.
• NTP Server: IP address of NTP server.
• NTP Port: Port of NTP server.
4. Click Apply to save and exit the interface.
The time synchronization interval can be set from 1 to 10,080 minutes, and the default value is 60
minutes. If the DVR is connected to a public network, use an 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 set in a more customized network, NTP software can be used to establish an NTP server
used for time synchronization.
11.2.4 Configuring NAT
Purpose
U
niversal Plug-and-Play (UPnP™) can permit the device seamlessly to discover the presence of other
network devices and establish functional network services for data sharing, communications, etc. Use
the UPnP™ function to enable fast connection of the device to the WAN via a router without port mapping.
Before You Start
To enable the device’s UPnP™ function, you must enable the UPnP™ function of the router the device is
connected to. When the network working mode of the device is set as multi-address, the default route of
the device should be in the same network segment as that of the router’s LAN IP address.
1. Go to Menu > System Configuration > Network > NAT.
