Turnstiles form pedestrian walkways to controlled areas and are typically used in upscale lobby entrances where high security, highspeed throughput and interior aesthetics are priorities. These single or bi-directional pedestrian control devices are used with the access control system to prevent tailgating and to grant or deny access into a facility. Normally used in conjunction with a guard station, these optical turnstiles can grant access to 30 people per minute per lane. Multiple form factor designs can be surfaced to match the interior of any lobby with standard or custom designs and finishes. An optical turnstile w/ barrier arms provides a visual as well as physical barrier which communicates that authorization is required before entering the secured area.
