This analytic detects when the field of view is obstructed. This can occur if the camera has been moved, if the lens is spray painted, or if a large object is placed in front of the camera. This is a general purpose analytic and should normally run on each camera.
No configuration is required; however, you can adjust the Analysis Resolution if necessary.
