Step 3: Set Daylight Savings Time and NTP Server
Settings
Daylight Savings Time
This is important for correct video recording.
• From the Device Parameters > DST Settings, to enable automatic daylight
savings adjustment click the checkbox Enable DST (the default behavior is
NOT enabled)
• Enter the correct dates and times for the time changes.
Figure 9: DST Settings
Note: DST Bias is a specific field for certain areas around the world where
daylight savings time adjustments are more than one hour. This setting allows
the system to adjust to these regions.
NTP
Time synchronization between IP devices is critical for effective and accurate
video recording. Many IP Cameras look for an NTP server or some other device
to synchronize their time to. Network Video Recorders like the TVN 20 are
interacting not only with other TVN 20’s but the many IP cameras that each is
carrying its own time. It is vital that all of these devices share a single common
time.
The NTP Server can be as simple as the Client/Server PC in an Interlogix’s
TruVision Navigator installation, or it may be a specific NTP server on the
network tasked with maintaining a unified network system time.
