1、What is blackbody? What is its function?
Blackbody can be simply understood as a constant temperature reference source. When testing human body temperature, blackbody is
generally set to 35 ℃ by default, which is used for temperature co rrection of thermal imaging acquisition, so as to meet the accuracy
requirements of ± 0.3 ℃.
2、Can it be installed in outdoor or semi outdoor environment?
Because the outdoor temperature, wind, humidity and other environmental factors have a great impact on the temperature
measurement of the thermal imaging surface, it is not recommended to be installed outdoors or in the area directly connected to the
outdoor, but in a closed and relatively stable environment without wind.
The best distance for temperature measurement?
The best temperature meas urement distance is the same as the distance between blackbody and equipment. 7mm detection distance is
3m, and the transverse width of 3m is about 1.3m; the temperature measurement value far from the optimal distance will be reduced,
and the temperature measurement value close to the optimal distance will be increase
5、How many heads can be tested?
In normal use, many people (1.3-1.5m in width) can't be placed side by side at the best distance of temperature measurement. There is
no limit to the number of heads in the detection area, but it is too far or there is overlap, which may result in missing or inaccurate
temperature measurement. It is recommended to test o ne by one.
6、Why does the image of thermal imaging channel get stuck after a period of time? Is it normal?
Normal. In order to ensure the image uniformity and temperature measurement accuracy, thermal imaging needs a period of time to
set the blank to zero for correction. During the process of setting the blank, the image will get stuck, which is a normal situation
7、Why thermal camera does not measure temperature after the first configuration
Sys tem time is not synchronized, refer to time synchronization setting in system debugging
