what does an infrared filter do

Ha!! Do A security camera needs to filter out the excess of light that hit the image sensor in order to generate good-quality video and that's done by using an infrared light filter that blocks unwanted light that comes through the camera lenses. The infrared filter blocks visible light but allows infrared light to reach the sensor to create the infrared image. A clear filter basically blocks nothing, passing all wavelengths from ~280nm through the entire visible spectrum and WELL into IR.
