What is the difference between low-light-level night vision and infrared night vision?
Infrared night vision does not rely on external light, can work normally in a completely dark environment, and can clearly present the temperature difference between the target and the surrounding environment. Even if the target is hidden in the grass, woods or caves, as long as there is a difference between its body temperature and the background, it can be easily found.
