Detection Images: 

The security provided by an access control system is compromised if an authorized person is followed by an unauthorized person. Tailgating can lead to asset and intellectual property loss and risk to employee safety. Accurance 3D has been designed to analyse the airlock area and detect if more than one person is present.

Accurance 3D system comprises a control box and one sensor for unidirectional applications and two sensors for bi-directional applications. The sensor itself includes a set of infrared LED illuminators and a “time of flight” sensor.
