7.3.11 Tampering
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 Duration
Minimum tampering duration is the time for video analysis to determine whether camera tampering
has occurred. Minimum duration could also be interpreted as defining the tampering threshold; a
longer duration represents a higher threshold. The tampering duration time range is from 10 to 3600
seconds.
