distance between the front of forehead and camera), the best test width at 3M is about 1.3m (about one gate), the forward temperature at 3M will be higher, and the backward temperature will be lower. The ideal situation is to place footprints at the 3M position to guide the thermometer to measure temperature one by one at the designated position. -

Page 12: Drawing Of Human Body Temperature Detection Area
The blackbody temperature is 35 (the default value). When drawing the area, double-click the image to enlarge to the full screen (double-click again to restore the original picture size after drawing). The green box in the figure below for the rule box should be drawn in the middle of the blackbody radiation surface, and the rule box should be as small as possible (the smaller the box, the higher the measurement accuracy, refer to the green box in the upper right corner of the image below). - Page 13 the head temperature of the subject exceeds 37.3 ℃ (Note: BF5401 has no audible and visual alarm) 2.2.4 Alarm temperature correction Due to the difference of environment, there may be errors in the temperature of the measured person. If more than 5 person samples stand at the best temperature measurement distance and the measured temperature is generally high or low, they can be compensated by temperature correction.

1. What is blackbody? What is the role? Do you need a physical connection to the camera? Blackbody can be simply understood as a constant temperature reference source (constant temperature can be maintained after power on). When testing human body temperature, blackbody is generally set at 35 ℃, which is used for temperature correction of thermal imaging acquisition, so as to meet the accuracy requirements of ±... - Page 17 Dav video with two channels on site.
