SOLUTION: OVERHEAD 3D THERMAL MAPPING SYSTEM
Convergint identified that the TSA was using wrong-way tripline analytics. After careful evaluation with a test camera at SeaTac Airport, the camera analytics could not recognize the collision of near-passing of subjects. Convergint then identified the appropriate solution would not be a camera analytic based on pixel movement, but rather a thermal image. Convergint identified a company called IEE, which creates 3D modulated light intensity sensor technology that would provide overhead 3D thermal mapping. The sensor would be able to detect people moving in the wrong direction during the deplaning process and was capable of bi-directional counting. Convergint leveraged the Lenel access control system to receive a signal from the IEE device when activity was detected. Lenel pushed a signal to an audible and visual alarm device to notify nearby gate agents. Once the activity is verified, the use of a wireless Inovonics device resets the alarm. There is also a manual on/off key mechanism that is utilized. The airline’s process outlines that the night shift supervisor disables the detection sensor and arms the POS doors after the last flight has deplaned, typically around midnight. The following morning shift supervisor would arm the system prior to the first flight deplaning, typically around 4:00 AM.
Finally, in order to ensure the system is functioning, the Lenel system is programmed to send an email to the airline in the event of power loss. The controller is network-based, and loss of network connectivity will not affect the system locally. In the case of a power fail utilizing battery backup, Lenel will send an email to several of the airline’s personnel to initiate a service call to Convergint.
