Closed circuit televisions (CCTV) come in a variety of styles and amounts of magnifications. They also tend to be expensive. Before you purchase a CCTV, consider having a Low Vision Examination with either an optometrist or ophthalmologist, who has had additional training in low vision, and discuss your desire to use a CCTV. Try to find a place where you can have hands-on experience with a variety of machines before purchasing one. It can take a little while to learn how to use a CCTV effectively; some controls on some machines will be easier for you to use than others. Take your time and check out what particular features work best for you. Some doctors and vision rehabilitation agencies offer loaner programs and/or resale of older but perfectly good machines, which could save you money. Read more about CCTVs on this web site.
