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
congurations in Event -> Event settings -> Trigger. For example, when the camera is
tampered with, camera can be congured to send pre- and post-event video clips to a
networked storage device. Please refer to page 95 for detailed information.
