Coronavirus - Thermal Imaging screens for elevated body temperature

This video is about using thermal imaging technology in screening for coronavirus. I have seen a lot of misinformation lately from sources claiming that you can simply point a thermal imaging camera into a crowd and "detect" anybody infected with the Coronavirus, flu, Ebola, SARS or any other infectious disease.

In this video, I explain how thermal imaging technology can be used to screen for people with an elevated body temperature.

The Coronavirus outbreak in Wuhan, China is currently all over the news. However, thermal imaging has been used in past to perform non-contact skin temperature measurements.

I want to set the record straight and explain the technology in layman's terms. How thermal cameras work, how you can use thermal imaging to measure skin temperatures and what you can and cannot detect.

There are also several pitfalls and challenges with this technology when it comes to detecting somebody with an elevated body temperature. Things that can affect the accuracy of the measurement are:

- Makeup
- Physiological Stress
- Sweating
- Insufficient Camera Resolution
- Measuring the wrong location on the face
- Not using a reference black body for calibration
- Using the wrong camera
- Subject motion
... just to name a few.

MoviTHERM offers a wide variety of thermal screening solutions. Measuring elevated skin temperatures using thermal cameras is now a widely used method as the country prepares for reopening. Screening visitors, employees, patients and contractors is an important part of the new guidelines published by State officials as well as the Center for Disease Control.
