Infrared camera refers to the kind of camera that can be monitored 24 hours a day. There are also ordinary infrared cameras and dot matrix infrared cameras. Dot-matrix infrared camera is better than ordinary infrared camera, with long irradiation distance, fine and clear image quality and longer service life.

The sensitivity of an infrared camera is infrared, within a certain wavelength range, such as 800nm- 1 100nm. In terms of spectrum, it is similar to the principle that ordinary cameras sense visible light. The working principle of the infrared camera is that the infrared light emitted by the infrared lamp irradiates the object, and the infrared light is diffused and received by the monitoring camera to form a video image.
