WHAT’S THERMAL ?
Any object with temperatures above absolute zero emits a detectable amount of radiation.
A thermal camera converts IR radiation into grayscale values, and matches grayscale values to temperature values through an algorithm model.
Thermal cameras with high temperature accuracy can help detect elevated body temperatures which may indicate the presence of a fever. Thermal cameras can be used for the fever screening of travelers, shoppers, and office workers.
It takes only one second for a thermal camera to detect temperature of a person, thus allows screening of large numbers of people at a time.
Thermal cameras feature non-contact temperature measurement from about one meter away, avoiding unnecessary physical contact.
