CAMERA SABOTAGE
The Camera Sabotage behavior detects contrast changes in the field of view. An alarm is triggered if the lens is obstructed by spray paint, a
cloth, or if it is covered with a lens cap. Any unauthorized repositioning of the camera also triggers an alarm.
Scene Setup for Camera Sabotage
Install the camera in a high position, looking down on the scene. The field of view should be as large as possible. A small field of view could
result in the view being blocked by an adjacent object.
Avoid scenes with a dark, uniform background; low lighting; and large moving objects.

Delay before alarm: Defines the delay between the time a violation is detected and the actual trigger of an alarm. If the violation does
not continue past the delay period, an alarm does not trigger. If the violation lasts longer than the delay period, an alarm triggers. The
default setting is 3 seconds.
Alarm severity: Defines the severity of an alarm to allow the prioritization of alarms.
