How to choose a long-wave infrared lens

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 long-wave infrared lens installation point is at night: if there is light or no light, whether the light is dim or no light environment, this determines how low the light source of the camera will automatically turn on the auxiliary camera to monitor, and the performance is good. Image effects; 2) Determine the approximate range that the long-wave infrared lens needs to see in the environment: if you want to see 30 meters, 50 meters, 80 meters, or 100 meters, at this distance * far, you need to see the activities of the objects or the faces of the people. The projection range can also be understood as ordinary light projection, but when using an infrared camera, the general infrared and camera lens have been determined to see the range. The infrared lamp and camera lens have already been made into a set of finished effects, so it’s not like ordinary The camera can easily change the lens to change the angle of view. It should be noted that the larger the night vision irradiation 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 actual needs, so as to obtain better width for some important areas. The scope of the monitoring effect.
