Power supply；
Infrared light supply exports infra-red radiation, on the camera lens or minute surface for projecting CCTV camera or monitoring camera, camera lens
Or minute surface absorbs light radiation, own temperature rise, so as to realize the function of dispersing fog.
Further, the infra-red radiation of the infrared light supply output, after optical filter filters off interference light, projects monitoring and takes the photograph
On the camera lens or minute surface of camera or monitoring camera.
Specifically, the fog intensity sensed with the inductor, as the infrared light supply intensity of light source automatically adjust or
Control parameter.
Specifically, when the work light of the camera lens or minute surface of CCTV camera or monitoring camera is visible ray, infrared light
The infra-red radiation of source output is projected after optical filter on camera lens or minute surface, is free of in the infrared radiation spectrum of infrared light supply output
Visible ray.
Further, described infrared light supply uses Electric radiant Heating Film.
Further, when the fog intensity detected by fog intensity inductor is less than " stopping " pre-set value, break
Open the power supply of infrared light supply；Infrared light supply stops output infra-red radiation.
Compared with the prior art, it is an advantage of the invention that：
1. using Electric radiant Heating Film be used as infrared light supply, heating efficiency height, system power saving, existing monitoring system will not be brought compared with
Big load increase；
2. by camera lens or the rise of minute surface own temperature to camera lens irradiation infra-red radiation, and then demisting is imitated
Fruit, demisting operating efficiency are high, it is easy to accomplish, fault rate is low in actual moving process, is easy to long-time steady operation；
3. the output of infrared light supply projects the camera lens or mirror of CCTV camera or monitoring camera again after optical filter
Noiseless to the optical treatment process of existing monitoring system on face, the function of original monitoring system is unaffected.
Brief description of the drawings
