Tampering
The Tampering setting can be found under this path: System > Tampering .
Tempering Alarm function helps the IP Camera against tampering such as deliberate
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.
