7.3.11 Tampering Alarm

The Tampering Alarm function helps the IP camera deal with tampering (such as, deliberate
redirection, blocking, paint-spraying, and obscuring the lens, etc.). Using video analysis, the camera
can react to such events by sending out notifications or uploading snapshots to the specified
destination(s).
Detection of camera tampering is achieved by measuring the differences between the older frames
of video (which are stored in buffers) and more recent frames.
Tampering Alarm
The tampering alarm function may be turned on or off in the Tampering Alarm page. The default
setting is Off.
