3. Tamper Detection
Camera Tamper Detection (CTD) detects tampering events in surveillance cameras that
may compromise the integrity of the video content. Examples of camera tampering
include obstructing the lens with paint or a foreign object, adjusting the lens' focus or
aperture settings, pointing the camera in a different direction, and turning off the lights (if
indoors with no major change in ambient illumination expected). CTD can tolerate the
effects of automatic camera gain, camera shaking that causes mild image jitter (less
than +/- 4 pixels in any direction), and dimly lit scenes.
