9.3.4.3
Tampering
The
Tampering
screen enables the camera to 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 notifications or uploading snapshots to the specified destination(s).
Figure 58: Tampering 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.
