Can the infrared camera see people clearly at night?

Brand model: Huawei Intelligent Dolphin Surveillance Camera

System: Extreme Edition

Infrared cameras can see people clearly at night. The shooting principle of infrared camera is that infrared light emits infrared light to illuminate the object, and then the infrared light is diffused and received by the monitoring camera to form a video image.

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 of the installation point of the infrared camera at night: whether there is light or no light, whether the light is dim or no light, which determines how low the infrared light of the camera is before the auxiliary camera automatically turns on monitoring, and obtains 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. 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.
