Abstract
An access gate for controlling access of individuals passing through a passageway to an access controlled area comprises a cabinet, bordering the passageway, and a movable barrier, attached to the cabinet and configured to open or close access through the passageway. The access gate further comprises a detector having a detection zone directed to a ground of the passageway. Capturing measurement data of individuals approaching the movable barrier is thereby limited to lower body extremities, including feet of the individuals approaching the movable barrier. An electronic circuit is connected to the detector and configured to determine from the measurement data received from the detector information related to the feet of the individuals approaching the movable barrier, and to detect tailgating of the individuals passing through the passageway, using the feet information.
