corona virus and Thermal Screening

Coronavirus and Thermal Screeing 

A coronavirus is a kind of common virus that causes an infection in your nose, sinuses, or upper throat. 

A coronavirus can infect both animals and humans.

Most coronaviruses spread the same way other cold-causing viruses do: 

through infected people coughing and sneezing, 

by touching an infected person's hands or face, 

or by touching things such as doorknobs that infected people have touched.



Common Symptoms of Coronavirus

The symptoms of most coronaviruses are similar to any other upper respiratory infection,including 

runny nose, 

coughing, 

sore throat 

and fever.



Thermal Cameras

All live objects emit infrared energy or heat. Unlike regular cameras that record 

light reflected by objects, thermal cameras use heat sensors that can record heat 

generated by the body of a person or an object to create a 2D image with differing temperature levels. 

When a person stands before the cameras, on the computer screens the hotter objects are 

highlighted with a different colour palette than the rest.These cameras can be calibrated 

to detect abnormal body temperatures such as over 101 degrees.



Thermal cameras are effective only to the point of telling 

who has a higher body temperature or is running a high fever. 

It may not mean the person is infected with coronavirus. 

Additional screening systems are needed for that.
