Closed-circuit television systems, or CCTVs, are electronic magnification aids. CCTVs are commonly used for reading newspapers and books, writing checks, filling out forms and other paperwork, and handiwork. CCTVs usually have a wide range of magnification powers available. They are available in a variety of prices and have many different features. The Madelia Lions Club selected the Merlin EVS system for placement in the Madelia Library. This system is a full-color, auto-focus, desktop video magnifier. It enables the user to view images in color, black and white, high contrast positive (edges sharpened black on white) or high contrast negative (edges sharpened white on black). It magnifies between 4x and 60x.
