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).
Figure 52: Tampering Alarm Screen
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.
