NTP allows using the camera as a time server for other MOBOTIX cam-
eras (see below under
Automatic Time Synchronization with a MOBOTIX
Camera
).

Time Protocol (RFC 868) should only be used for cameras that use an ISDN
Dial-Out connection to access the time server.

Software Camera Manual Part 2
Keep an eye on the
ISDN Dial-Out limits
Note
Automatic synchronization with the time server will only be performed,
if Adjust periodically has been activated. The camera has to be able
to access the time server using the local network or an ISDN
connection.
Caution
Note that a MOBOTIX camera with a configured ISDN dial-out
connection (or default route set to ISDN) will try to establish an ISDN
data connection for every periodic synchronization. When using an
external RFC 868 time server, this will happen at every reboot and
again every six hours; using an external NTP time server (RFC 1305) will
open a permanent connection to the Internet. This may very quickly fill
up the camera's automatic dial-out limits (Admin Menu > ISDN
Connections > Dial-Out Parameters).
If one of the counters exceeds the limits, dial-out is blocked for the rest
of the day/week/month, respectively, and the camera will not send
any images or messages any more.
In case you have deactivated the dial-out limits, the camera may incur
high costs as it is trying permanently to establish dial-out connections.
MOBOTIX recommends to use periodic time server synchronization
with due caution and—if required, to make sure to have flat-rate
Internet access or a time server on the local network, which
synchronizes with another (external) time server.
