Pedestrian access is a balance between security and movement. The correct gate should verify one person at a time without creating unnecessary queues, while supporting emergency release, accessibility and the credentials already used by the facility.
Tripod turnstiles: durable everyday control
Tripod turnstiles provide a clear physical checkpoint at factories, schools, gyms, transit areas and staff entrances. They are compact, economical and available in semi-automatic or motorized configurations. A typical flow rate of roughly 25–40 people per minute is suitable for controlled staff movement when credential-reading time is included.
During an emergency, fail-safe arms can drop to create a free passage. For outdoor or semi-outdoor use, confirm enclosure material, ingress protection and drainage rather than relying on an indoor cabinet.
Flap barriers: fast and space-efficient
Flap barriers use retracting wings to create a modern, compact lane. Infrared sensors monitor passage and help detect obstruction or tailgating. Products such as the PRANN Astra F7 can support high pedestrian flow in offices, IT parks, metro environments, hotels and clubs.
They work best where users are expected to present a valid credential and move through a clearly defined lane. Wider accessible lanes should be provided for wheelchairs, luggage and service movement.
Speed gates: premium experience and precise sensing
Swing-glass speed gates are suited to corporate headquarters, airports, banks, data centres and premium commercial lobbies. Their fast opening movement, refined finish and multi-pair safety sensing support a more welcoming experience while retaining controlled access.
Because the barrier leaves are taller and the mechanism more sophisticated, lane design, floor loading, cable routing and sensor calibration deserve careful attention during installation.
Full-height turnstiles: maximum perimeter control
A full-height turnstile provides one-person-at-a-time entry for high-risk sites such as industrial plants, prisons, stadium perimeters and critical infrastructure. It resists casual bypass far better than waist-height equipment and can be integrated with card, QR, biometric or face-recognition systems.
Selection should always consider throughput, access credential, emergency behaviour, accessibility, environment and the required level of physical deterrence. PRANN SYSTEMS can combine different gate types within one site while maintaining a unified access-control platform.
