Camera Tampering Detection
This section explains how to set up camera tampering 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 make use of the camera tamper detection function:
1. Select the Enable camera tampering detection checkbox.
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. Congure a system by selecting the event Trigger as Camera Tampering Detection on Application
page > Event Settings /Server Settings (how to send alarm message) / Media Settings (send
what type of alarm message). Please refer to page 90 for detailed information.
