The time synchronization interval can be set from 1 to 10080 minutes, and the default value is 60
minutes. If the DVR is connected to 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 set in a more customized network, NTP software can be used to
establish a NTP server used for time synchronization.

Purpose
Universal Plug and Play (UPnP™) can permit the device seamlessly discover the presence of other
network devices on the network and establish functional network services for data sharing,

of the LAN IP address of the router.
