Detecting video tampering
Video tampering, such as moving a camera to a different position, can also be detected
and set to trigger an action on the NVR. Not all IP cameras may support this feature.
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 Management > Tamper Mask.
2. Select a camera to configure for tamper-proof.
3. Check the Enable Tamper Mask box to enable the feature.
4. Define a tampering detection area.
The tamper detection area setup interface lets you define an area on-screen where
you want camera tampering to be detected. Click and drag the mouse across an
area to mark that area for video tampering. You can only set one tampering area
with the full screen being the maximum area. Click Clear to clear the window.
