Fastlane optical turnstiles offer a similar level of security as a traditional ? height turnstile, by utilising active infra-red beams to create an invisible detection field, doing away with the need for a physical barrier. Fastlane optical turnstiles have the fastest throughput with 1 person per second. The lack of a physical barrier ensures an open appearance to complement the most diverse design requirements. The Fastlane design concept allows a flexible approach to providing effective access control in areas where previously security had been desirable but the associated aesthetic implications had been unwelcome and prohibitive.
