Thermal imaging cameras, also called infrared cameras, detect the heat given off by an object or person. Thermal imaging cameras have lenses, just like visible light cameras. But in this case the lens focuses waves from the infrared energy present in all objects onto an infrared sensor array. Thousands of sensors on the array convert the infrared energy into electrical signals, which create a video image. The infrared camera measures and displays a “thermal profile” of objects in relation to the temperature of surrounding objects. So a person, warmer than the surrounding air, appears “white” while the cooler surrounding air or buildings will appear in varying shades of gray.

Unfortunately, not every thermal camera is appropriate for body temperature screening applications. Obtaining actionable data requires adequate thermal resolution and measurement accuracy, as well as the correct preparation and scanning methodology. The Optris temperature screening software and hardware is specifically designed for mass screening of body temperatures.

Thermal cameras are being used today in public spaces such as airports and hospitals and by essential services such as manufacturing and shipping as an effective tool for measuring skin surface temperature. People who are identified as having an elevated skin temperature can then be screened by medical professionals using additional tools such as an oral thermometer.

Thermal screening is not designed to act as a medical diagnostic tool.  Thermal screening can however be deployed as an additional aid in screening potential COVID-19 carriers.

How close the individual needs to be to the camera depends upon the resolution of the camera. Resolutions of less than 382 x 288 are therefore not recommended for mass screening. Additionally the target should fill the field of view to enable precise measurements. Dramatic variations in ambient temperatures can also impact measurements. The right resolution and correct subject distance will minimize false negative percentages.

Not really. Although, if, for example, a suspect had a gun under their shirt, its exterior area would appear “cooler” to the camera and indicate to police that someone may be carrying a gun.

The infrared thermal imaging camera detects the infrared radiation emitted by the object itself and forms an image of the surface temperature distribution of the object. The higher the temperature of the object, the greater the infrared radiation energy will be.  Infrared human body temperature measurement combined with intelligent software algorithms enables fast, convenient monitoring and discrimination of body temperature in public settings.


  • There is a strong correlation between core body temperatures and measurements made with IR cameras.
  • Thermal imaging is not intended for use as a medical diagnostic tool but as an additional aid to screening a large sample size for individuals with heightened temperature profiles. 

No, those “greenish” images are really night vision, not thermal imaging. These cameras, which consumers can buy for a few hundred dollars, amplify dim available light to simulate daylight. Thermal imaging cameras are more expensive and don’t rely on visible light. Instead, they produce a “thermal profile,” which highlights the temperature differences of objects.

Mass Screening Made Easy

Diverse Applications

Schools, hospitals, airports, churches, offices, banks, public transport, manufacturing, grocery stores etc. are some examples of potential sectors that could benefit from deploying this technology.

Body temperature screening is not a medical diagnostic tool. It may be used in combination with other medical diagnostic tools as an additional aid in identifying individuals with temperatures above a predefined threshold.
