Turnstile Entry — Practical Column Purpose
Control pedestrian flow and secure entry to restricted areas (stations, stadiums, offices).
Types
Tripod (mechanical) Full-height (high security) Optical/virtual (sensor-based, no barriers) Swing/gate turnstiles (ADA-friendly options) turnstile entry
How it works
Integrates with access control: ticketing, RFID cards, mobile QR, biometrics. Unlock sequence: present credential → verification → arm/gate unlocks briefly → entry counted → re-locks.
Key features to specify
Throughput rate (people/minute) — typical: tripod 30–40, optical 60–80, full-height 20–30 Direction control: uni/bidirectional Fail-safe behavior: lock or unlock on power loss Integration: protocol support (Wiegand, OSDP, TCP/IP), SDK/API availability Safety: obstacle detection, anti-tailgating sensors, emergency egress compliance Environmental rating: IP rating for outdoor use Durability: MCBF (mean cycles before failure) ADA compliance: alternative accessible gate or paired swing gate Aesthetics/finish: stainless steel, powder coat, tempered glass options
Installation checklist
Site survey: power, network, floor mounting, traffic analysis. Foundation: concrete pad or anchor bolts; ensure level. Power & comms: provide redundant PoE or low-voltage supply; route OSDP/Wiegand as required. Integration: test with existing access control, ticketing, or payment systems. Safety setup: program sensor sensitivity, emergency unlocking, signage. Commissioning: throughput testing, failover scenarios, user training. Maintenance plan: cleaning, lubrication, firmware updates, spare parts. Key features to specify Throughput rate (people/minute) —
Operational best practices
Use optical units where high throughput and accessibility needed. Pair tripod with an accessible lane to meet ADA. Configure anti-tailgating alarms and logging for incidents. Provide staffed override during peak events or system faults. Regularly review logs to spot misuse or bottlenecks.
