The observed target You are observing the target Observe the target directly without the disappears. through the glass. presence of glass. The image quality is poor or the detection range shortens. These problems are likely to occur when you use the device in harsh weather

(such as snow, rain, and fog). When the device is used at a low temperature, the imaging quality is poorer than that at a normal temperature. At temperatures above 0C, the temperature rise varies with the observed objects (environment and background) due to different heat conductivity coefficients. As a result, high-temperature contrast occurs and the image quality is better. At low temperatures, the observed targets (background) usually cool down to a similar temperature because of reduced temperature contrast. Therefore, the image quality (details in particular) is poor, which is a characteristic of thermal imaging devices.
