Thermal Imaging Cameras can assist with Fever Screening by detecting elevated body temperatures in large groups of people, in under 1 second, with accuracy up to ±0.3°C.

Any object with a temperature above absolute zero emits a detectable amount of infra-red (IR) radiation. The higher an object’s temperature, the higher intensity of emitted IR. Taking advantage of the differences in IR intensity between objects, thermal cameras make the invisible IR “visible” in the form of heat zone images.

The cameras provide colour images and temperature scales, and sound alarms that can be set to go off when a certain temperature threshold is exceeded. These functions make it easy for an operator to instantly decide whether the subject needs to be referred for medical examination.

The pandemic has generated immense interest in thermal imaging cameras as a tool to identify individuals with elevated body temperatures. We’ve put together a collection of Frequently Asked Questions FAQs about thermal imaging cameras to help you understand the technology.
