12.8.1.1 SNTP
Selecting Sync with SNTP Server from the drop down opens the
SNTP Server Address box where the server automatically
receives time updates, which can be configured. See
http://www.pool.ntp.org/en/
for a list of publicly available time
servers.
The configuration of an SNTP server provides a means of
synchronizing the onboard clock of the CCFC with the specified
SNTP server. This ensures that the camera clock is always
accurate. It is also possible to configure a time zone offset for the
camera.
Other than the address of the SNTP server, the time zone needs to
be selected and the Adjust for DST (daylight savings time) can
also be selected.
