Scene Change Detection
Scene change detection detects the change of surveillance scene caused by external factors
such as intentional camera movement. The NVR takes snapshots and reports an alarm when
the detection rule is triggered.
1. Go to Menu > VCA > VCA Config.
2. Select a camera.
3. Select Scene Change Detection and click
to configure it.
4. Set the alarm-triggered actions and arming schedule. See 4.7.5.1 Alarm-triggered Actions
and Arming Schedule for details.
5. Set the sensitivity by dragging the slider. The higher the sensitivity, the more likely scene
change behaviors will be detected, but the false alarm rate will increase.
6. Click Apply.
