MAC-SAFE-T-CHECK, thermal screening, turnstiles, access control, covid-19 screening


Ironton, OH August 31, 2020 Modular Security Systems, Inc. (MSSI) is excited to announce that it has collaborated with Scientific Research Corporation (SRC), Atlanta, GA, on an access-control solution that can screen for skin temperature. Specifically, SRC will be outfitting MSSI’s patented 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.

“We are in an era where it appears that the ‘new normal’ will require employers to take every step possible to prevent any employees who may have COVID-19 symptoms from entering a workplace,” said Robert Slagel, President and CEO of MSSI. “That being said, there are many essential industries that must try to retain a ‘business as usual’ approach to their operations. Our new MAC Safe-T-Check outfitted with the HAT technology from SRC will help worksites, such as construction sites, military bases and government facilities, quickly test their employees for elevated temperature before allowing them entry.”

The operation of the MAC Safe-T-Check is based on the design of MSSI’s industry-leading 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 within SRC’s HAT 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 2-4 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 1.5 meters (5 feet). The temperature recording speed of the HAT provides for an average throughput rate of 10-12 people per minute.

“As businesses try to ensure that every employee who enters their property is healthy, automated thermal imaging of skin temperature will become more common,” said Terry Shatzer, Director for SRC. “We are proud to work closely with MSSI in developing a temperature-scanning solution for the MAC Safe-T-Check that is quick, reliable, secure and safe as we continue to adapt to the new everyday realities of living in a COVID-19 world. And when we move beyond COVID-19, this technology will remain relevant as a way to increase confidence that workplaces requiring access control are safe, secure and healthy.”
