What kind of turnstile is used in high security applications and may feature an integrated counter?

A full-height turnstile is designed specifically for high-security applications due to its robust construction and operational functionality. These turnstiles extend from the floor to the ceiling, creating a physical barrier that prevents unauthorized entry while allowing only one person to pass at a time. This makes them particularly effective in environments where security is a paramount concern, as they limit the potential for tailgating or unauthorized access.

The integration of an electronic counter in full-height turnstiles further enhances their utility in security applications. It tracks the number of individuals entering or exiting a secured area, providing valuable data for security monitoring and access control. This feature is crucial in high-security environments, where maintaining accurate records of personnel movement is necessary for safety and accountability.

In contrast, waist-high turnstiles are less secure, as they do not provide the same level of physical deterrence against unauthorized access. Optical turnstiles, while offering quick pedestrian throughput, rely on sensors and may still allow for the possibility of multiple users passing simultaneously. Biometric turnstiles, though incorporating identification technologies, may not provide the comprehensive physical barrier that a full-height turnstile offers. Thus, the full-height turnstile is the most appropriate choice for high-security applications.
