NTP server settings 
A Network Time Protocol (NTP) server can also be configured on your recorder to keep 
the date and time current and accurate. 
Note: If the device 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) or europe.ntp.pool.org. If the device is setup in a more 
customized network, NTP software can be used to establish a NTP server used for time 
synchronization. 
To set up an NTP server: 
1.  From the menu toolbar, click Network Settings > NTP. 
2.  Check the NTP box to enable feature. It is disabled by default.
