IRISYS IRS2100

The IRS 2100 works in conjunction with an access control system to detect a person following a cardholder through a controlled door. The Tailgate Detector is based on the Irisys high-accuracy thermal imaging people counting technology, detecting people by their body heat. It operates by receiving a signal from the access system for each valid cardholder accepted at a door and comparing the number of valid cards with the number of people entering. In the event that someone follows a valid cardholder through the door without presenting a valid card/token a tailgate alarm output is generated.
