• Interval: The tampering detecting interval. Take the diagram below as
example. The interval is set for 30 second; the camera lens is covered during
10 - 40 sec. At time point B, the camera compares the view with time point A,
and sends an alarm when it founds that the lens is covered. At time point C,
the camera compares the view with time point B, and sends an alarm when it
founds that the lens is uncovered.
