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-320B, which includes PC, monitor, blackbody and stand. The AIO-320B 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.
1) Thermal camera: 384x288 pixels micro-bolometer thermal sensor camera
2) Visible camera: 2MP USB interface camera
3) Blackbody: set to 40℃ before shipment
4) Ultrasonic distance measuring instrument(measure face temperature when a person reached a certain distance(2.5m)
5) Monitor (11.6-inch) all-in-one PC (shipped after installation of the Fever screening Manager program)
6) Stand and base
7) Accessories (adaptor and manual)
All though the method of use is very similar to that of existing COX fever screening cameras, CF320B.
AIO320 all-in-one fever screening camera measures temperature of faces when it is within a certain range, like 3.5m to 1m, to increase the consistency and accuracy of temperature measurements.
Users who feel that the 11-inch monitor is small can connect a large monitor which supports HDMI input to the HDMI port on the AIO320 unit
Unlike Chinese products that adopted thermopile array sensor, people who pass by do not need to stop and bend their back to fix their face at 30 cm in front of the monitor to measure face temperature, but pass 3.5m to 1m away from the camera with the speed of moving to measure face temperature.
Built-in black body just in front of the lens makes the thermal camera measure the temperature exactly all the time by minimizing influence of environment. Further we do not need to do cumbersome work of installing the blackbody on the tripod.
1) Measure the face temperature most accurately.
