Motion detection can be used to detect unauthorized entry, for example, if a member of staff leaves by an unapproved exit. Specific areas of interest can be defined in a scene and searched automatically through a recording to identify and view any significant motion that occurred during the recording. This is hugely useful when searching for motion in a quiet area throughout a long period of recorded video. It can be tuned using parameters such as object size and sensitivity. A "no-motion" option lets you monitor things that should be moving and alert when motion stops, e.g. escalators and conveyor belts.
