Can the infrared perspective camera see the room through the curtains at night?

Infrared ray only plays the role of illumination. You can take photos with an infrared camera when there is no light at night, but the photos are black and white.

Among the infrared rays, there is a kind of near infrared ray, which can penetrate people's clothes, reach people's skin, and then reflect, which provides a theoretical basis for using infrared cameras to see through people's clothes and other objects.

General cameras are optical cameras, which can only capture visible light. There is a thermal imaging camera, which can capture infrared light with a lower frequency than visible light, and can also capture a general outline in the dark.

Extended data:

The infrared camera needs to determine the camera type according to the specific use environment, especially the night environment, as follows:

1. Investigate the light source environment where the infrared camera installation point is located at night: whether there is light or no light, whether the light is dim or no light environment determines how low the infrared light of the camera is, and the auxiliary camera will automatically turn on to monitor and achieve good image effect.

2. Determine the approximate range that the infrared camera needs to see in the environment: If you want to see 30 meters, 50 meters, 80 meters or 100 meters, at this farthest distance, you need to see the movement of the object clearly or you must see the face of the Truman. Projection range can also be understood as ordinary light projection. However, when choosing an infrared camera, the range of infrared light and camera lens has been determined, and a set of finished products has been made for infrared light and camera lens.

3. It should be pointed out that the larger the night vision exposure area, the higher the cost and the greater the energy consumption. Therefore, users can install auxiliary infrared light sources in some important areas according to specific practical needs, so as to obtain good monitoring effect in a large range in some important areas.
