2.2.6.8 Directional Motion
The Directional Motion behavior generates an alarm in a high traffic area when a person or object moves in a specified
direction. Examples of typical installations for this behavior include airports, entrances and exits, and vehicle traffic through
tunnels. In an airport installation, cameras observe passengers boarding a plane in a terminal. If a person moves in the opposite
direction of the normal flow of traffic, an alarm triggers. In a tunnel installation, an operator wants to observe traffic flow. If a car
enters a tunnel through an exit, an alarm alerts the operator to activate the traffic signals to stop all traffic in the tunnel. In an
entrance or exit installation, a camera is pointed at an exit door. If a person tries to enter through the exit door, an alarm
triggers.
