Cross Line Detection detects people or objects trespassing in restricted areas. When a network camera detects moving objects in its view, the camera starts tracking each one of them. Once the object crosses an imaginary line in pre-defined direction, incoming, outgoing or either direction, it sends an alarm.
When a person, vehicle, or other object crosses a virtual line that has been defined, the line crossing detection function detects it, and when the alarm is triggered, specific actions can be taken.
