The Sure-Fi Wireless kit eliminates the need to run wires from the door to the remote door controller. There is a small box that connects at both ends, one at the controller and one at the reader. These transceivers can relay Wiegand information to the controller and also accept signals from the controller to unlock at the door. The door unit has a relay that is used to control a lock directly. The transceivers can also handle door position switch (DPS) and request to exit signals (REX). Reliable military-grade wireless link can push over a mile of distance through walls and over 50 miles line of sight, like a boss.
