Recording of an alarm event starts automatically if any camera has registered an alarm event. Video recording stops immediately after the end of an alarm event or in a pre-defined time interval after it. With some program settings, the pre-event fragment with a pre-defined duration can be automatically added to the beginning of the entire recording.

Recording of an alarm event doesn't start if:

  1. the Alarm recording option has not been enabled for the camera—recording is not activated when the main detector registers an alarm event.
  2. the Alarm option has not been enabled on the camera's additional detector—recording is not activated when the additional detector registers an alarm event.
