Fever detection screening thermal cameras for non-contact body temperature measurement

These fever detection thermal cameras are specially designed to measure temperatures in the range of human body temperature. Normal human body temperature ranges from 97°F (36.1°C) to 99°F (37.2°C). A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness. Here is an interesting article about the principles and the technologies behind these fever screening devices. "Can You Use an Infrared Camera to Detect a Fever?" on wired.com on April 09, 2020 by Rhett Allain. Handheld fever detection thermal cameras have LCD screen where thermal images and temperatures are displayed. A preliminary fever screening system consists thermal imaging camera, PC and data collecting and analysis software. Here is the FDA guide about thermal imaging systems used to fight COVID-19, "Thermal Imaging Systems" by FDA.

Benefits of thermal camera screening systems:

Fast measurement and immediate results
Non-contact, 2 to 14-feet away
Easy to set up and portable
High accuracy
Auto alarm high temperature
