Soundy 1 Posted March 13, 2012 Normally the only time you'll see an IR cut filter mentioned is if it's a removable type (ICR) in a "true day/night" (TDN) camera. Generally safe assumptions are: If it's a B&W camera, it has no cut filter. If it's a color camera, it does. If it's a color camera with IRs, it does not. If it's a "day/night" camera (as opposed to TDN) it does not. Make me wonder how well the camera performs without one... Remember the reason for the IR cut filter in the first place: CCD and CMOS sensors are sensitive to IR light, but with color sensors it can adversely affect color balance and possibly exposure, and because it focuses differently than visible light, it can make it difficult to attain a sharp focus. Thus the cut filter is used on color cameras to help achieve proper color rendition and prevent focus issues. Without it, your colors may be off, but you may also get slightly better night performance. Share this post Link to post Share on other sites
