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 106 for detailed information.
