The new ES520 Anti-Tailgate Device from Designed Security, Inc. (DSI) can help you put a stop to unauthorized access. The enhanced ES520 uses a wider infrared beam to detect tailgating through any standard doorway, setting off an alarm when more than one person enters at a time. Itâ€™s affordable, configurable, and easy to install. With the ES520, tailgating is a security risk you no longer have to take.
