Modular Security Systems, Inc. (MSSI) has collaborated with Scientific Research Corporation (SRC) on an access-control solution that can screen for skin temperature. Specifically, SRC will be outfitting MSSI’s MAC Safe-T-Check modular access-control portals with its Health Assessment Terminal (HAT) technology. HAT is an automated wall-mounted thermal imaging system that quickly and reliably screens skin temperature before allowing entry into a commercial or industrial construction site, government facility, military base or other venue.
As the COVID-19 pandemic continues to affect large swaths of the country, it remains imperative that those who may be exhibiting symptoms of the virus not be allowed to interact closely with other individuals. In this case, a quick temperature scan at the entrance to a construction site or government facility will help indicate whether or not a person might be infected.
The operation of the MAC Safe-T-Check is based on the design of MSSI’s MAC Portal, which houses full-height turnstiles in a climate-controlled portable shipping container for secure site access control that can be relocated where and when needed at a jobsite or venue. The MAC Safe-T-Check combines all of its features with the HAT technology from SRC, creating an access control unit that screens workers for elevated temperature, and also ensures they have the proper security clearance.
The thermal sensor meets the U.S. Food & Drug Administration’s April 2020 accuracy specification guidelines for thermal imaging devices. The HAT is installed on the wall of the MAC Safe-T-Check Portal. The worker pauses for two to four seconds in front of the HAT screen, at which time the person’s skin temperature is scanned. The results are displayed to the worker and the turnstile is opened, allowing access to the work site. The results of the temperature scan can also be sent to a remote monitoring station via WiFi or an Ethernet connection. The HAT unit has a temperature accuracy of +/- 0.3ºC (+/- 0.5ºF) between 36ºC to 40ºC (96ºF to 104ºF) when taken at a distance of 5 ft. The temperature recording speed provides for an average throughput rate of 10 to 12 people per minute.
