IR cut of CCTV camera is made up of two filters. One is infrared filter. This one is able to collect or cut-off the infrared of in the air,and another is regular. The infrared of in the air can get through this kind of filter.
At present, most of IR-Cut technology was used to Cmos sensor,because of the cmos sensor has the inborn defect in illumination. It needs more infrared to ensure that the cameras have enough light to ‘see’ the object in the night and also needs to cut-off or collect the infrared during daylight,so IR-CUT was invented. At daylight, in order to keep the cmose sensor reflect more real image, infrared filter will working, collect and cut-off the infrared of in the air,and when the night coming,infrared filter will be automatically switch. Regular filter will be working,then,more infrared can be through the filter, so the cmos sensor is able to see the object.
This is the principle of IR-cut,and this is a good design. Now it's very popular.
In borsche company,this technology has been used very maturity. Almost all the security CCTV camera models can be mounted with this IR-cut. Besides,the price of this technology is cheap. The IR cut CCTV camera with Cmos sensor is lower than CCD camera,so many many customers likes it,and this will be a trend.
