In order to prevent the spread of diseases by the infected people, there are smart surveillance devices that can detect abnormal body temperature from the distance using specially designed high precision thermal imagers.
These thermographic cameras will first detect human faces using its deep learning artificial intelligence and then analyze each face using the thermal image and get the exact temperature reading of the face.
If the temperature is too high and the person is suspected to have a fever, the camera triggers the alarm immediately.
There are many critical locations where the temperature screening is critical, especially during the pandemic - hospitals, schools, government buildings, retail stores, factories, airports and others.
