Fast Facial Temperature Scanning Eliminates Staff Wait for Building Entry


During the COVID-19 pandemic, a large employer instituted a temperature screening policy as part of their health, safety and security protocol. They initially hired a third-party company to conduct the screening. Employees reported to large tents in the parking lot to have their temperatures taken by hand-held digital thermometers before entering the building. If an employee had a fever, the individual was not permitted to enter the building.

  • The manual process was both time consuming and expensive, requiring significant staffing during peak entry hours.
  • With nearly 1,000 employees arriving at the same time each day, it could take an hour or more for people to get through the temperature screening lines.
  • Long delays for building entry significantly reduced productivity and employee satisfaction.


SIGNET worked with the large employer to engineer and install automated facial temperature scanners at all main entry points. Instead of waiting in line for manual temperature screening, employees can just look at a thermal imaging screen on their way in the door for an instant temperature reading.

  • The thermal imaging technology is fast, contactless and highly accurate, taking only seconds to return a temperature reading. This allows employees to enter the building at their normal rate of speed, eliminating long delays for manual temperature readings.
  • The scanner is connected to the building access control system. If the scanner detects that an employee has an elevated temperature, their ID badge will not work to unlock the door. Employees who do not pass the initial screening must report to HR for a secondary manual temperature reading. If their temperature is confirmed to be elevated, the employee is required to quarantine until they have a negative COVID test and a normal temperature reading.
  • The system is accurate to within a tenth of a degree, providing much higher accuracy and reliability than the hand-held digital thermometers used previously. The temperature threshold (e.g., +/- 1°F) can be controlled by the organization in accordance with the latest scientific recommendations.
  • Recorded data can be easily analyzed to identify when and how many times individuals have arrived with elevated temperatures or look for trends in the number of people arriving with elevated temperatures.
  • The automated system is less expensive to maintain than the third-party approach for manual temperature screening. It also provided immediate productivity gains by eliminating long waits to enter the building. With these savings, the company recouped its investment in about 60 days.
Automated facial temperature screening helps organizations comply with CDC guidelines and reduce the risk of spreading disease by keeping people with an obvious sign of illness out of the building. Regardless of industry, organizations benefit from adding fast, accurate temperature scanning to their health, safety and security protocol.
