Note: It is strongly recommended not to configure for video tampering when using PTZ
dome cameras.

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
