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 for analog/HD/TVI cameras. You can select a specific area for IP
cameras.
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 Camera Setup > Camera Tamper.
2. Select a camera to configure for video loss detection.
3. Check the Enable Camera Tamper box to enable the feature.
4. Select the tamper detection sensitivity level by clicking the sensitivity scroll bar.
Higher sensitivity is to the right of the bar. The maximum sensitivity value is 3.
5. Select the arming schedule for the tamper.
Click Actions and then select the Arming Schedule tab to select the day of the
week and the time periods during the day when motion can be recorded. You can
schedule up to eight time periods in a day. Default is 24 hours.
