8MP 1/2.5" 20/22mm IR CUT filter M12 lens mount double filter switcher for cctv camera

Inside the camera CCD or CMOS use day and night filter cause the camera image partial color in the daytime, night vision low illumination effect is poor, so day and night filter can't meet the current CCTV surveillance industry application of high-definition digital products, when the camera is color, it will automatically use the pulse signal to make the switch move to IR CUT filter, taken out such the camera image near the object of primary colors, nature. when the camera is night vision, it use the pulse signal to make the switch move to the AR filter once again, this image sensors can be induced to the all wavelength of the light, so that the camera is better image brightness and resolution, was made objects easier to identify.

IR-CUT filter:

Auto-regressive filter (AR-filter):

40 ohms resistor wire color is red and black 1.25 * 2 p * 80 mm * 0.6 mm.

Function:
1. Fixed daytime color cast problems, enhancing the brightness at night. IR-CUT filter switch automatically according to external light along with the strength of automatic switching, making the image to achieve the best results. That is, during the day or night, the dual filter can automatically switch filters, therefore, whether in the next day or night, can get the best imaging results.

 2. According to the instruction automatic switch infrared cut-off and the full spectrum glass, day and night switch, automatic positioning, in order to achieve infrared end filter work during the day time, sunshine is vivid, restore the true color. Full spectrum glass work at night, and increase low illumination, night vision is very clear.

 3. Use on the camera board, to modify the problem of partial color, out of focus, let video images do not lose focus, unbiased color and excellent resolution.

 4. To filter the hard light to make the picture color soft, to accieve human eyes visual color.
