  1. I have a CCTV surveillance system of 12 cameras. The cameras that look at wide driveways and flat yards and fields work great at night. However 2 cameras look down paths (used by coyotes) with high bushes along each side. Regardless of where I place these cameras, the IR light is always too bright on the bushes which swamps out the view along the path. It seems that if I had a camera with a narrow field-of-view then the bushes wouldn't be in the picture and I could see the path. Is it possible to just add a simple (cheap) lens to narrow the FOV? If so, any suggestions would be appreciated. Or Is there any material I could use to mask off the IR beam along the edges without lighting up? I was thinking of putting tape along the sides of the camera to block IR light to the bushes but I think the tape would light up even more than the bushes. Unless maybe there is a material that refracts IR wavelengths out of the FOV without reflecting it back into the FOV of the camera. My system uses Q-See cameras and DVR.
