Users can draw zones of any shape on any feed. These zones track not only entry and exit, but also length of time spent in the zone. This can be used to make restricted zones, which trigger a real-time alert if anyone below a certain clearance level enters them. The timing aspects of zones can be used to detect loitering, or to do zone-time analytics. This gives useful data to businesses on where their patrons spend the most time. Outdoor cameras can use zones to monitor parking lots, either by timing cars in limited time parking spots, or by using license plate recognition to monitor reserved parking.
