A built-in IR illuminator provides an effective night vision range of up to 500'. A side rail enables accessories, like another illuminator, to be attached directly to the monocular. The screen displays color images during the day, and black and white when the night vision is on for great clarity and contrast. Enhancing the optical 3x magnification is a digital zoom to provide up to 9x magnification. An RCA video-out port allows an external monitor or recording device to be attached to view and/or record the live feed.
