Case Study - Major Canadian International Airport Mantrap Tailgating Solution

May 25, 2023  |  SonnySekhon


A major Canadian Airport was experiencing tailgating at their various mantraps/vestibules that separated secure and unsecure areas. 

Quanergy Solution

Quanergy’s mantrap solution, which consists of MQ-8 series LiDAR sensors and QORTEX DTC perception software, can detect tailgating through secure portals with far higher accuracy than proprietary optical imaging systems. The solution sees everything in 3D, unlike camera-based systems that only see in 2D. It offers the coverage, granularity, and accuracy that’s needed to provide a hyper accurate people count which is the most critical component of the entire solution.


The LiDAR based access control system will do a “count,” determine if there’s just one person in the mantrap or vestibule, and then it will trigger the opening of the door to the secured area. After the employee exits into the secured area, the secured door closes again, and the LiDAR does another count to ensure there’s no one left in the vestibule before the next person can then approach the outside door. If there were two people counted in that mantrap, the secured door would not open because the LiDAR would detect both people. This isn’t the case with less-accurate systems. Here’s the typical solution workflow:

Solution Overview

One of the major problems with legacy solutions  set up in these mantraps is that they rely on visual sensors such as cameras or T-DAR systems for counting people. These solutions are inaccurate,  unreliable, very sensitive to lighting or environmental changes, and most importantly, easily defeatable by malicious actors. In contrast, Quanergy’s LiDAR-based portfolio has the ability to count the number of people in the room with hyper accuracy and is rapidly becoming the solution of choice to combat tailgating in matraps/vestibules at major data-center sites and airports.

Quanergy’s solutions complete existing access control systems rather than replacing them. Quanergy’s LiDAR-enabled mantrap solution allows users to keep leveraging existing investments as it seamlessly integrates with the leading access control solutions, VMSes and cameras. Organizations that need higher security with broader coverage and no blind spots can use Quanergy’s solution to complement what they already have in place.

Quanergy’s solution addresses all major mission-critical security use cases including perimeter intrusion detection, server rack and cabinet security, mobile security towers, man trap/vestibule access controls, and rooftop security through the following core competencies:

  • Only provider of seamlessly integrated 3D LiDAR sensors and software solutions
  • Over 95% reduction in false alarms
  • 95% people detection, tracking and classification accuracy
  • 360° 3D coverage and up to 15,000 square meters of coverage per single sensor
  • No privacy concerns or recording of Personal Identifiable Information (PII)
  • Over 30 integrations with leading Access Control Systems and VMSes such as Milestone, Genetec, Hanwha, Network Optics, Digifort, Flir, Mirasys, Surveil, and ONVIF based camera vendors such as Bosch, Hanwha, Flir, Axis, and other solutions such as PSIMs like Advancis and Analytics platforms, etc.
