The Dynamic drop arm barrier is the ideal solution for contactless access control. Installed here are two Dynamic barriers combined with a facial recognition reader, ensuring only verified access. The pedestrian faces the reader and within 1 second, the reader verifies the person and the barrier arm drops to the safe position. Optical sensors follow the pedestrian past the cabinet and when it is safe to raise, the barrier arm raises rapidly to restore the integrity of the entrance. If an obstacle is detected during the raise cycle, the barrier arm automatically lowers and waits until it is safe to raise once again.
