Product Summary

dormakaba developed anti-backtrack lanes (sometimes refered to as one-way exit corridors) to guide the flow of arriving passengers at the air terminal.  They perform the task of preventing arriving passengers returning to airside areas, simultaneously preventing non-passengers from entering areas such as baggage claim or passport security control areas.

This modular system is equipped with a series of motion presence and video analytic sensors that are designed to detect unattended objects left within or passed through the corridor area. As passengers exit through the corridor, full-height and half-height double swing doors automatically open and close based upon a programmed flow or interlock mode. Combined, the physical barrier and advanced sensor technology provide a secure detection and entry prevention solution without the need of a guard.
Some benefits of anti-backtrack lanes, include:

•    Stainless-steel construction
•    Customisable configuration
•    High throughput
•    Safety sensors prevent unintentional contact with the moving door panels
•    Modular construction supports a multi-lane configuration

The dormakaba anti-backtrack lanes manages the egress of passengers in one direction, from airside to landside. A combination of microwave, infrared and video sensors monitor the entire area of the corridor to detect, notify and isolate unauthorised access from the landside area.

While serving as a high security deterrent to access, the dormakaba anti-backtrack corridors implement an advanced level of safety sensors, positioned to protect authorised persons as well as identify unauthorised intruders.
