How is it triggered?
Events may be triggered by one of the several sources. In the example below, Motion Detection region 1
is used as the event trigger.
You may also ask the event to be repeatedly triggered during this scheduled time. The interval is
determined in minutes. You may use this with email / FTP upload to take snapshots at regular intervals.
DIs: For selected models only, the IP device may be triggered by Digital Input.
Motion: You may trigger the event if one or many Motion Detection regions encounter a motion trigger.
Trigger from any of them will initiate the event. The duration of event will be the same as the MD trigger
length, or the Trigger interval time, defined in the Motion Detection section on Video Adjust page.
Video Loss: This is available for video servers only. When the analog video in is lost, the video state will
become “lost”, and return to “normal” only until device receives analog video signal. A common scenario
is for Video Server to send email to administrator when video is lost, and activate DO signal to alarm that
persists until the analog signal is restored.
Switch to Night mode: This is available to selected models only. When camera changes between day and
night modes, the embedded event handler will notice this change, and may act upon this information.
Potential uses include changing the motion detection profile to another set of Event MD parameters. By
having two sets of parameters each optimized for day and night, this provide better overall accuracy in
both day and night conditions. Some night time only MD regions may also be activated this way. The
event period will end when the camera returns to day mode, which will then reset the camera to the
original settings.
Device boots successfully: This will trigger the event responses once the device boots up. You can use
this to create a notification system that keeps record of when the device has been rebooted via email.
Reboot device: This triggers the event response when the device is shut down via web UI “Save and
Reboot”. Use this to keep record of when was the device setting edited. Note that this will not take effect
when the device is unplugged, as this is not normal shutdown.
