Optris introduces fever detection system

May 29, 2020 -  Optris has now launched a system based on the current version of the PI 450i infrared camera, which has an optical resolution of 382 x 288 pixels. Together with the included PIX Connect Software, the surface temperature of a person’s face can be measured even when they are just passing by. The system can be used with two different methods: The temperature of people in a crowd can be recorded, or people can be checked individually for an elevated temperature. The second method provides more reliable results because the temperature measurement can be taken at the eyelid where the temperature has the strongest correlation to the body’s core temperature. Optris provides the appropriate optics to perform the measurements at an optimal distance using both methods.
 
The PI 450i infrared camera has a thermal sensitivity of 40 mK. To increase the absolute accuracy of temperature measurement, which is typically ±2°C for infrared cameras, the PI 450i can be used in combination with a reference radiator.

The BR 20AR type radiator is equipped with an internal temperature sensor. This reference signal is processed in the PIX Connect software. This allows for an overall accuracy of the system of ±0.5 °C. The software runs on any standard PC. Temperature thresholds for example can also be defined, which automatically trigger an alarm if they are exceeded.
 
The system can be used wherever contactless checking of many people for an elevated body temperature is necessary to prevent a virus from spreading further. Possible places of application of the system include airports and railway stations as well as hospitals, schools, offices, shopping centers and more.
