This section explains how to set up camera tamper detection. With tamper detection, the

spray paint.

Please follow the steps below to set up the camera tamper detection function:

1. Check Enable camera tampering detection.

2. Enter the tamper trigger duration. (10 sec. ~ 10 min.) The tamper alarm will be triggered only when the

tampering factor (the difference between current frame and pre-saved background) exceeds the

trigger threshold.

3. Set up the event source as Camera Tampering Detection on Event > Event settings > Trigger.

Please refer to page 116 for detailed information.
