Anti-Tailgating Access Control Definition:

Anti-tailgating access control refers to restricting an unauthorized person from gaining access through a turnstile or gate after an authorized person has already gained access. Tailgating, also referred to as “piggybacking”, is a major security concern, making anti-tailgating turnstile systems necessary for many applications.

Variations: Barriers and Sensors

The two ways to prevent tailgating are the use of physical barriers and/or optical sensors. Optical turnstiles use sensor beams to detect passage. These barrier free optical turnstiles alert security guards of possible piggybacking or tailgating with visual and/or audible alerts. Physical anti-tailgating barriers include full height turnstileswaist high turnstiles, and barrier optical turnstiles that only allow access to a single person at a time.

Anti-Tailgating Applications:

Pedestrian tailgating is a security vulnerability for all automated access control systems. Anti-tailgating access control systems are used to minimize this risk and ensure that only people with proper credentials gain access to a secured area.
