SmartCatch  Human Loitering

SmartCatch is an accurate and effective solution for detecting loitering in sensitive areas. Using existing
CCTV infrastructure, SmartCatch software monitors, identifies and tracks objects for security policy violations and enables quick response through real-time alerts and instant video replays. At the core of SmartCatch is a set of advanced video algorithms capable of performing complex behavioral analysis, tracking numerous objects and simultaneously identifying security threats in even the most complex environments. Human Loitering is one of many available SmartCatch behaviors.
The human loitering algorithm detects humans from a CCTV camera and tracks their movement. Loitering is detected by SmartCatch when the human movement remains within the camera view or part of a camera view (as specified by the user) for a minimum period of time (also specified by the user.) Loitering includes any type of human movement such as running or walking within a loitering range by at least one human in the camera view.

Multiple humans may loiter near or at the same time and SmartCatch tracks each loiterer individually.
