The Tripwire function triggers an event when an object moves
across a virtual line in one or both directions.
Intrusion Detection /

The Intrusion Detection function triggers an event if an object
remains in the area to be monitored for longer than the set
time.

Detection of a sudden increase or decrease in volume at the
audio input of a channel.

This function triggers an event if the image content changes
seriously. A twisting of the camera can thus be detected.
