Product description

The CF320 fever screening camera released in the 2nd half 2020 is designed to minimize the influence of the surrounding environment in temperature measurement, such as changes in the temperature and wind, by installing a black body about 3 meters in front of the camera.

COX's adopted thermal camera is an analogue thermal camera that transmits full pixel temperature raw data over an Ethernet port instead of a thermal network camera, unlike other Chinese companies. The thermal network camera compresses thermal video and transmits compressed video data and additionally sends only a few pixels of temperature data uncompressed, so it only send maximum temperatures in the face detection area processed by the camera itself, without any constant on-site calibration as analogue camera can do, which naturally reduces the accuracy of the temperature measurement.
However, what COX adopted is that the thermal camera transmits only the temperature raw data of the entire pixels measured by the camera and the PC program running on the PC processes the received temperature raw data to produce thermal images and also obtain the temperature value of each pixel. PC’s processing capability is much greater than that of a thermal camera, so PC software can additionally calibrate the temperature value obtained by processing received temperature raw data from the camera based on the black body's 40 ℃ temperature, and it can also be calibrated by distance between people and cameras.

In conclusion, additional calibration based on 40℃ blackbody and distance between people and camera, CF320B adopted, offers more accuracy in face temperature measurement of fever screening camera.


The product configuration is the same as CF-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.
