Tampering Alarm function helps the IP Camera against tampering such as deliber-
ate redirection, blocking, paint spray, and lens cover, etc through video analysis
and reaction 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.
