Camera tamper

You can setup the recorder to alert you when the camera view has changed such as
when someone has deliberately blocked the camera view by spraying paint on the lens
or by moving the camera. Tampering detection only applies when the whole image is
covered and all light is blocked. You cannot select a specific area of the camera screen
to detect tampering.
Note: It is strongly recommended not to configure for video tampering when using PTZ
dome cameras.
To set up video tampering detection:
1. From the menu toolbar, click
2. Select a camera to configure for video loss detection.
3. Check the Enable Tamper-proof
4. Select the tamper detection sensitivity level by clicking the sensitivity scroll bar.
Higher sensitivity is to the right of the bar.
