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.

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, communications, etc. You can
use the UPnP™ function to enable the fast connection of the device to the WAN via a router without port mapping.
