FAQ | Solution FAQ
1. What is the 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 correction of thermal imaging acquisition, to meet the accuracy requirements of
±
0.3
℃
(
±
0.54
°
F).
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 outdoors, but in a closed
and relatively stable environment without wind.
3. Why is it recommended to measure the temperature of frontal forehead?
•
A person’s forehead offers the best temperature reading except for an internal body temperature (thermometer)
•
A person’s temperature reading comparing the forehead to the side of their face of the same person / same position will have a slight difference
due to blood-flow and other factors. Even with masks, the high temperature points are mainly in the forehead, ears and neck, and the
temperature is different among different people. Therefore, it is required to face the camera and test the frontal temperature uniformly to
reduce the impact of temperature difference between different parts of the face.
