Configuring an NTP server
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 an 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 an NTP server used for
time synchronization.
To set up an NTP server:
1. From the menu toolbar, click Network Settings > NTP.
2. Check the Enable NTP box to enable feature. It is disabled by default.
3. Enter the NTP settings:
• Interval: Time in minutes to synchronize with the NTP server. The value can be
between 1 and 10080 minutes. Default is 60 minutes.
• NTP server: IP address of the NTP server.
• NTP port: Port of the NTP server.
4. Click Apply to save the settings.
