The Inner Workings of Optical Turnstiles

Optical turnstiles combine advanced sensors with sophisticated design. They offer a refined method for managing entry. This makes them popular in contemporary, high-traffic settings.

How They Work

Optical turnstiles operate using multiple arrays of infrared light beams. These beams span the pedestrian lane at varying heights. As a person passes through, they interrupt these beams. The system then analyzes the sequence and pattern of these interruptions.

• Authorized Entry: When a valid credential (such as a facial scan or QR code) is presented, the system expects a single person to pass. The pattern of broken beams should align with this expectation.
• Unauthorized Entry: If multiple individuals attempt to pass on a single credential (tailgating), or if someone tries to enter without authorization, the system detects an anomalous pattern. This triggers an audible alarm and, in some cases, flashing lights.
• Safety Features: Modern optical turnstiles include advanced algorithms to distinguish between people, luggage, and small objects. This helps prevent false alarms and includes anti-crawl and anti-climb detection capabilities.
