Rugged Cams H.4 - Manual (Page 73)

Description of features
1. Time synchronization
1) Synchronization with the NTP Server
Time is synchronized with the NTP server every hour.
A. Automatic Setup
The nearest server from the user’s zone will be selected for connection. If the connection
fails, the next nearest server will be chosen.
B. User Setup
The user sets the URL or IP for the NTP server. If connection is not established, a message
will be sent to the user, and the related log, saved.
If synchronization with the NTP server fails, synchronization with RTC will be established.
2) Synchronization with the DVR Time Server
The DTS server is executed in the H.4; time is synchronized every hour. H.4 DTS clients
referring to the DTS synchronize the time of the DVR system operating with DTS.
When the DTS time or a zone is changed, the change is reflected on the H.4 belonging to
the network (the synchronization signals are broadcasted without passing through the router
or gateway). The DVR time server does not support automatic connection.
2. Daylight saving time (DST) setup
Regardless of whether NTP server or DST server is referred to, DST is automatically
processed according to the time.
3. User time setup
The user can set the time directly.
For the NTP client setup, the user can read the time but not change it.
