Turnstile access control refers to using turnstiles and gates to control entry into or exit out of an area. Access may be controlled to allow one-way access or bi-directional access. A security turnstile gate, like a full height or waist-high tripod turnstile, controls access by allowing only one person to pass through its barriers at a time. Additionally, turnstile access control systems can be programmed so that different parameters can be set to determine who has access to an area and when. Further entry can be controlled by card readers and advanced biometric scanners to allow for autonomous operation.
There are various types of security turnstiles used for access control. Full height, tripod, and optical turnstiles along with ADA gates are all used to control access. They vary in level of security also, with optical turnstiles having the lowest level of security and full height turnstiles having the highest. Access control turnstiles and gates can further vary based on appearance. Optical turnstiles have a high-quality appearance with their stainless steel construction and glass panes. On the other hand, full height turnstiles have a rugged appearance that is best used to portray safety and impenetrability.
Turnstile access control systems are used to restrict access, provide security, and control people traffic. They bring order to crowds exiting stadiums, amusement parks, and sporting events and provide security to high-risk areas like corporate lobbies, data centers, and construction sites. Finally, they are used to check credentials like tickets and authorization cards.
