With outbreaks such as SARS, Bird Flu, Ebola, and now COVID-19, we must work not only to find cures but more effective ways of detecting when an individual has a fever. Outbreaks of infectious diseases seem to affect millions of people within this country and around the world. As we become more of a global conscious society, a fever detection system is necessary to get through airports, businesses, and schools to prevent large scale infections.

Great minds were able to come up with a solution in the form of an infrared thermal imager. This infrared imager captures an individual’s body temperature. The fever diagnostic system is an innovative method to identify and monitor high fevers in large populations. This device activates an automatic warning when a person with increased body temperature, which is often an indication of fever, passes by the camera.

What Is a Fever Detection System?

Taking the temperature in a typical way has not been effective in this age of pandemics. Having to take the temperature one person at a time is a slow process for our fast-paced world. What’s even more ineffective is self-disclosing when asked if you have a fever. We needed a more reliable means of screening large numbers of individuals at a time. Having a faster way to screen people can make a difference in the day to day operations of a business, hospital, or airport. Using an infrared thermal fever detection system seems to be the best alternative to the one man at a time method that we currently have in place.

An infrared thermal scanner can identify individuals with high temperatures from entering spaces with many people. The infrared scanner is a non-invasive heat detector, or a thermal imaging method of finding, tracking, and analyzing temperature patterns. The system determines whether the person’s body is in a state of normal or abnormal human temperature. This system allows hospitals, schools, airports, and businesses to scan large crowd of people as they pass by the scanner.

The mass infrared thermal fever screening system is more reliable in monitoring. It is even quicker and considerably more accurate than conventional means of finding a person’s temperature. This new method is a more cost-effective means of screening people than in the past.

Fever Detection Technology

Several companies are selling their infrared thermal devices to various organizations, including hospitals and airports. Infrared works by a short wavelength of light, showing the heat, usually in the facial area, sending the information back to a camera to interpret the results and flag anyone with a temperature above a certain level.

Some might argue as to the validity of these mass-screening devices. The skepticism is because these devices can only sense surface body temperature, which is lower than an oral temperature. Furthermore, infrared thermal imaging devices need corrective adjustment to account for temperature fluctuations.

If businesses were to attempt to capture thermal imaging from people and simultaneously measure their temperature using a standard thermometer, it would not be easy to accomplish. Although there are other determining temperature methods (oral or rectal), the infrared system seems less invasive, with excellent reliability. It protects those who are conducting the scanning from being up close to individuals who may have a virus. Being safe is always going to be the best choice.


Despite the limitations and imperfections of the new infrared thermal image fever detection system, it’s the most effective system we have at the moment. It’s the only way to assess large numbers of people before they get on an airplane or walk into a hospital. No system is perfect at the beginning stages. In time, this fever detection system has the potential for saving countless lives.
