Access to restricted areas

Smartly controlling restricted areas means to create a system that controls automatic traffic barriers and let in authorised vehicles only.

Some of the applications can be parking areas reserved for employees in facilities, entrance reserved for the police force in particular areas, bus entrance in reserved parking zones, truck entrance to loading zones into commercial areas and many more.

Sky Light wireless sensors are placed before the traffic barrier that delimits the restricted area. When a vehicle approaches a barrier or gate, a camera activates to recognise the plate number. If the vehicle is authorised to enter, the barrier opens automatically.

Sky Light Interface Card, which is a component of the Intersection System, transmits information to the local control unit that actuates the camera.
