Tailgate Detection System

The Detex AT-5200 Tailgate Detection System assures that only one individual enters a secured doorway for each authorized card read. Compatible with most card reader technologies, the AT-5200 is easy to retrofit. This unique and cost effective optical security system, which uses infrared sensor beams to detect tailgating, is perfectly suited for areas requiring tighter security.

Tech Tip     



The AT-5200 was designed for easy installation. The mounting brackets can be used as a template for screw holes and wire runs. Additionally, the Single Touch Calibration procedure does away with time sensor alignment.
