Non-contact fever screening


Harlequin uses infrared (IR) camera based thermography to accurately detect body temperature, providing a fast, non-invasive, and non-contact method of screening individuals at risk of infection.

A fever is the body's natural response to fighting infections such as Covid-19, and in-depth research has shown that infrared (IR) camera based thermography can be used to accurately detect elevated body temperatures.

Since the Covid-19 outbreak, significant time and resources have been invested in the development of effective screening technology to help keep the public/employees safe, and contain the spread of the virus.

Harlequin enables mass fever screening for use in factories, offices, airports, public buildings, schools and apartments.

The technology accurately measures the temperature of the eyes, as this yields the closest correlation to core body temperature. Other methods of mass fever screening such as infrared (IR) temperature guns, contact thermometry and self-reporting health declarations are not only often inefficient, but also ineffective.

Note that there is extremely high demand at present for this product so acting fast is essential to avoid significant lead times.
