Tampering
To edit the tampering settings, select System> Events> Tampering.
Tampering 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.
Tampering Alarm
The default setting for the Tampering Alarm function is Off. Enable the function by selecting On. You

Tampering Duration
Minimum Tampering Duration is the time for video analysis to determine whether camera tampering
