What is the main difference between night vision and thermal night vision?
1. In total darkness, thermal imaging night vision device has obvious advantages
Because the thermal imaging night vision device is not affected by light, so the thermal imaging night vision device in total darkness and ordinary light observation distance is exactly the same distance. While the second generation and above night vision devices, in total darkness must use auxiliary infrared light source, and auxiliary infrared light source distance is generally only up to 100 meters. So in a very dark environment, the observation distance of thermal imaging night vision device is much farther than traditional night vision device.
2. In harsh environments, thermal imaging night vision cameras have obvious advantages
In foggy days, rainy days and other harsh environments, the observation distance of traditional night vision devices will be greatly reduced. But thermal imaging night vision device will be affected by the small. 3.
3. In the light intensity changes a lot of environment, thermal imaging night vision device advantage is obvious
We all know that traditional night vision devices are afraid of strong light, although many traditional night vision devices have strong light protection. But if the environmental brightness changes a lot, it will have a great impact on the observation. Thermal imaging night vision devices, however, will not be affected by light. It is for this reason that the top car night vision devices, such as Mercedes-Benz BMW on the use of thermal imaging cameras.
4. In the target recognition ability, the traditional night vision device will have an advantage over the thermal imaging night vision device.
Thermal imaging night vision device, the main purpose is to find the target, identify the target category, such as the target is a person, is an animal. The traditional night vision device, if the clarity of the case is enough, is able to recognize the character of the target is who, is able to see clearly the five senses of the person.
