Digicon Tripods provide superior access control by both detecting and deterring unauthorized entries. When entering a facility, common solution to secure the facility is to add a card or biometric reader and electric locks to the door. While a reader and lock requires a valid credential to unlock the door, it cannot control how long the door is open or how many people enter. Unauthorized individuals can follow authorized personnel through the secured door, resulting in a common security issue referred to as “tailgating”. Additionally, a door cannot isolate the direction of authorized passage. For instance, if a door is activated for entry, it will not be able to prevent exiting at the same time while it is open.
Unlike doors, Digicon turnstiles can limit the number of people who can enter or exit on each presented credential and control the direction of passage. In order to enter through a turnstile, a person must first present a valid credential. This signals the barriers to unlock and allow one person to pass before immediately relocking.
