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. You can configure Tampering Detection as a trigger element to the proactive event configurations in Event -> Event settings -> Trigger. For example, when the camera is tampered with, camera can be configured to send pre- and post-event video clips to a networked storage device. Please refer to page 117 for detailed information.
