Camera Tampering Detection
This section explains how to set up camera temper 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 Application page > Event Settings /
Server Settings (how to send alarm message) / Media Settings (send what type of alarm
message). Please refer to page 79 for detailed information.
