Full Metal CS Interface Switch CS dual filter small lens IR-CUT switch. ICR, which uses the pendulum structure and PPS (aluminum) raw materials, work long-lasting, robust, easy to slip silk degumming, easy zoom, and a high temperature in the plant by 80 ℃, low temperature up to -20 ℃ (can be used Similarly, Russia; Harbin and other cold regions), 100,000 times reliability testing uninterrupted work to achieve the highest standards in product advantages: the use of Magnetic pulse power, calls the self-test, day and night auto switch, automatic positioning, sunshine colors. realistic, night vision infrared transparent no noise, correcting color cast out of focus and so on, to make the picture softer colors, to the human eye visual color consistency. 1, what is IR-CUT IR = infrared = IR CUT = filter, reducing surveillance cameras areas: an infrared filter, let deadline or through, the image called: Dual filter switch 2, IR-CUT filter switch dual role of the camera for daytime color cast correction problems and enhance the brightness of the night. IR-CUT filter switch dual principle of dual IR-CUT filter switch is: filters (an infrared cut filter and an all-or absorbed through the spectral filter) + dynamic part (can be electromagnetic, electrical or other power source) composition. Nature there are various wavelengths of light, the human eye to identify the range of light wavelengths between 320nm-760nm light over 320nm-760nm the human eye can not see on, such as infrared light, ultraviolet light, etc. 3 CCD camera imaging components or COMS can see most of the wavelength of light, due to the participation of a variety of light, cameras restore the color with the naked eye can see there is a deviation in color, a color cast to try to resolve the problem: The current program is posted in front of a CCD monolayer or multilayer (while allowing visible light and infrared light through) filter peaks. During the day due to the infrared light into the CCD and other miscellaneous interfere with color reproduction, such as green plants become pale, pale red clothes, etc. (sunny outdoor environment is particularly evident); during the night due to the filtering effect of bimodal filters, so CCD can not take full advantage of all the light, noise and low light performance unsatisfactory. IR-CUT dual filter switch in the full light of day, IR cut filter work, CCD restore the true color when insufficient light at night, the infrared cutoff / absorption filter automatically removed, all filtered through the spectrum ray film to work, to make full use of all light CCD, thus greatly improving the low light performance. 4, IR-CUT is good or bad from three aspects: 1 filter 2 power drive control circuit 5 part 3, Usage: Suitable for IP Camera network camera, megapixels HD camera, infrared night vision cameras, bolt cameras and other equipment.
