Adjusting Clocks with the NTP Server

If the times set in the system clocks of all VR-509 that are linked

synchronized in accordance with the NTP server settings when
multiple VR-509s are connected together.

The NTP server registration setting cannot be carried
out when recording is in progress. It is possible to

registration has been set to [YES].
When time synchronization with the NTP server has
been enabled, time adjustment will be carried out once
every hour.
