IMMUNOTHERM   Fever Screening


We in the 21st century live in a very fast-moving world. The fact is that with the growth of this fast-moving dense population the diseases also find their way to spread faster. If we take a brief look at what has happened, we can see that the Ebola Virus has crossed National and International boundaries to affect and take the lives of thousands of people in few hours. The same has happened with MersCOV-Middle East Corona Respiratory Virus that originated in KSA, SARS, H1N1 and Bird Flu.

Thermal Covid-19 Screening 

Accuracy in terms of elevated body Temperature reading using infrared may differ since they are some factors that may affect temperature accuracies such as human, environmental factor, and equipment variable. It is also limited by the fact that the thermal device measures skin temperature and not the core body temperature.  Therefore, each thermal imager should be able to understand febrile from normal subjects and by knowing how his device works.

Here we introduce this complete solution for mass screening “IMMUNOTHERM” by Digital Thermal Power. This compact, miniature, and portable set of IMMUNOTHERM set up features option to scan and isolate sick/infected persons from a fast-moving crowd.

Powered with an advanced Thermal Imaging Camera the solution is designed to detect a temperature variation as small as 0.05°C with the help of its thermal resolution of 640 x 480 pixels. The system supports up to four cameras in a single interface. A customizable Field of View of each camera is available in 120, 250, and 450 lenses as per the requirement.

Fever Screening Area Environmental Factors

Infrared detects infrared radiation and human skin absorbs radiation that may come from the sun if a person is exposed from direct sunlight in a long period this may affect the accuracy. Since Thermal camera usually measures the temperature o a surface of an object by interpreting the density of an infrared signal emanating from that surface and reaching the camera itself. Fever screening is not effective when used outdoors since it cannot be positioned to direct sunlight, outside lights, reflective lights. Ambient temperature is central to the controlled environment. Temperatures too warm or too cold for comfort (18°C to 24°C is optimal and ISO recommended) can affect the accuracy of the target temperature reading.


Flir  Thermal Camera Device Variables:

Each thermal camera has an individual specification to provide an accurate reading for elevated body temperature.

NETD (Noise Equivalent Temperature Difference) is closely related to thermal sensitivity. The very minimum to avoid thermal noise is NETD of 100mK (0.1°C), but nowadays we have an expectation of 50mK with the ability to detect temperature differences of 0.05°C. The ideal spectral range is 7.5 to 13 microns.

In addition, ISO has established technical guidelines for the application:

The device should carry out a self-correction (NUC) and it must operate in near real-time for rapid screening.
