The Mid-Sized Optical Turnstile is designed for small to mid-sized lobby/entry applications where styling is important. These turnstiles monitor pedestrian traffic flow through an access control point and assure that only one individual can pass for each valid access signal, thus eliminating "Tailgating". Sensing pedestals form pedestrian walkways at the entrance to a controlled area. An individual must be granted access by the facilities access control system in order to pass between the pedestals without activating an alarm. These units are compatible with most types of access control systems and can be field configured for Card-In/Card-Out, or Card-In/Free-Exit.
