The CG320 fever screening camera is a fever screening camera model that was first released by converting the CG320 model, which was sold as a radiometric thermal camera for temperature measurement, into a fever screening camera.
In April 2020, as the number of new confirmed cases of Covid19 continued to increase in Korea, quarantine authorities and the Ministry of Education promoted a project to install fever screening cameras in elementary, middle and high schools across the country to separate students suspicious of having fever from other normal students. COX, Korea's largest un-cooled thermal camera manufacturer, has installed a fever screening camera solution that combines CG320 and PC programs named One channel analyzer in all elementary, middle and high schools in Seoul which is the capital city of Korea, Daejeon, and Jeonbuk province based on CG320 radiometric thermal camera.
The above photo is captured from the BBC's report program, which shows how K-quarantine(quarantine system in Korea) has become an example of the world, and shows CG320 fever screening camera and One channel analyzer program running on a PC. You can view the BBC report at the link address below in this page.
1) CG320 fever screening camera
2) PC program (One channel analyzer)
3) LED strobe(The strobe flashes when a person suspicious of having fever is detected)
4) Tripod For camera installation
It is a system configuration that can distinguish people who are suspected of fever with just a thermal camera.
And it measures the face temperature of people on the move without stopping, and the PC program collects the measured face temperatures and processes it with a sophisticated algorithm and converts the last measured person’s face temperature to relative body temperature to accurately identify the person suspected of having fever.
