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.
