AXIS Blocked View Detection
AXIS Blocked View Detection is an application that triggers an alarm if tampering of the camera is detected, for example, if the
lens is covered or sprayed.
For optimal performance, we recommend that the camera view contains objects, patterns or lines that can be detected.
Avoid large areas of floor, walls and ceiling with few objects.
You can set the trigger level by adjusting the sensitivity and change ratio of the tampering detection.
