Applications > Tampering detection
This section explains how to set up camera tamper detection. With tamper detection, the
camera is capable of detecting incidents such as redirection, blocking or defocusing, or
even 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 113 for detailed information.
