Korea's quarantine system, which is called K-Quarantine, is a good example of coronavirus prevention around the world, has not implemented Lockdown at all, unlike Western countries, and has lowered the infection rate by efficiently inducing individuals to wear masks. In addition, K-Quarantine has installed fever screening cameras at most entrances to schools, public buildings, and crowded buildings to measure the face temperature of those who enter the building and filter out people who are suspicious of having fever, to basically prevent those who have heat from entering the building. In the first half of 2020, COX provided all elementary/middle/high schools in Seoul, capital city of Korea, with CG320 cameras, and in the second half of 2020, it released CF320B fever screening cameras with combination of visible camera, thermal camera and black body. In February 2021, COX once again released the most reliable easy to use all-in-one fever screening camera, named AIO-320, which includes PC, monitor, blackbody and stand. The AIO-320 fever screening camera uses a 384x288-pixel microbolometer sensor dedicated to thermal cameras that can measure the face temperature of people on the move the most accurately at the current technology level, including black body in the camera configuration, minimizing changes in the environment (temperature, wind, etc.) to get very high accuracy of +/-0.2℃ in measurement.
The product configuration is the same as AIO-320B except that the blackbody is not included.
If the ambient temperature of the site where camera is installed changes, the measured temperature can be changed, because blackbody is not included in the configuration. However, Fever screening Manager processes a certain number of recent face temperature measurements to get the distribution of measured face temperatures and check if last measured face temperature is close to or far from the median value of the distribution to determine if camera outputs an alarm signal or not, and consequently minimizes the influence of environment, even though blackbody is not included in the package.
