(4) Q: Why is the measured body temperature not 36°C?
A: Different parts of the human body have different temperatures. Skins on the forehead, cheek, and
limbs are often exposed. Temperatures at these parts are largely affected by the ambient temperature,
ambient humidity, and the grease and sweat on skins. In normal cases, they will not be higher than 36°C.
For a person staying in a cool outdoor environment for a long time, a body temperature measured below
10°C is also normal. The temperature of skins exposed to the sunlight for some time is often higher than
36°C and can even reach 40°C.
(5) Q: Does Night Vision Go pose a radiological hazard to the human body?
A: Night Vision Go does not actively emit any hazardous radiation but only collects the heat information of
objects. It can be used with peace of mind.
(6) Q: The temperature readings of people at a distance are relatively lower and can get higher when I
come close to them. Why is this happening?
A: The infrared radiation attenuates after passing through the atmosphere. The farther the distance is, the
more it attenuates. As a result, the temperatures measured are less accurate for objects at a distance. For
users who need only to find abnormal heat sources, the distance attenuation does not affect the relative
temperature distribution. So they can use Night Vision Go as usual. Users who need accurate
temperature data can obtain the corrected temperature by inputting the distance from the object to be
measured (up to 5m) in Personal Center - Setting - Temperature Measurement Correction - Distance
Correction.
