For many people with impaired vision, a CCTV is a powerful and welcome tool as they seek new ways to use their remaining eyesight. A CCTV is video magnifier that enables users to continue reading a variety of materials and, with some models, also facilitates handwriting.

Based on the technology originally developed for the security/surveillance field, CCTVs have been used by visually impaired people for more than 30 years. A CCTV system uses a stand-mounted or hand-held video camera to project a magnified image of a user-selected printed matter onto a dedicated video monitor or a TV screen.

CCTV systems have limitations, but here are several advantages to consider as you decide whether a CCTV is the right tool for you:

• Viewing the screen from a normal reading distance enables people with binocular vision to use their vision better.
• The zoom lens allows for rapid change in magnification.
• Reverse contrast option (white on black) may be less fatiguing for eyes.
• Easier handwriting abilities than conventional magnifiers.
• Higher level magnification than possible with purely optical solutions.
• A larger field of view is sometimes helpful.
• Moveable viewing table may help people with field restrictions keep their place when reading.

CCTV Designs

CCTVs currently come in two basic designs: stand mounted or hand held. To use a stand-mounted CCTV, you place the reading material flat on the unit’s viewing table (like a small desktop) under the camera. To make viewing easier, stand-mounted units usually feature a moveable viewing table that can glide from top to bottom and from side to side, making it easier to navigate through the material. Stand-mounted models are good for reading and are particularly effective for handwriting because your hand can easily fit under the camera on the viewing table. Many people use stand-mounted units for reading the newspaper or books, reading and paying bills, or reading and writing letters.

In contrast to stand-mounted units, hand-held units are more flexible systems that make it possible for you to position the camera on the material that needs viewing rather than requiring you to place the material on a unit-based viewing table. Depending on the model, the image is then shown on a dedicated video monitor, attached to a standard TV, or, if battery-operated, used with a portable small flat video screen or a headmounted display. These units can magnify almost anything within reach of the camera, including labels on food and medicine. Hand-held units frequently include rollers that make it easier to move over a table. Some hand-held cameras include, (as an accessory), a fixed stand that attaches to the unit for hands-free operation.

Technological innovations continue to expand the ways you can use CCTVs. Some now offer a split-screen feature allowing simultaneous viewing of computer data and the CCTV images on your computer monitor.

Common Features

Available in black and white or color, CCTV systems come in various screen sizes. All black and white CCTV systems offer a reverse contrast option of viewing black letters on a white background or white letters on a black background.

Controls for contrast and brightness are also standard on today’s units. Video monitors generally provide a sharper image than do some televisions, and many CCTVs that use a dedicated video monitor may include special features such as underlining/over lining text options or masking (viewing one line of text at a time).

Price Range and Payment Options

For many people, CCTVs are an investment, but a very worthwhile one. Many models have a range of magnification that allows users to continue using them for many years even as vision continues to change. Most machines come with a two-year warranty. Through the years, we have found most machines to be very durable with little need for repair. Extended maintenance contracts can be purchased on a year-to-year basis, and there are local service centers if repairs are necessary.

CCTVs available through CSBPS are competitively priced at the Manufactured Suggested Retail Price (MSRP). What’s more, net proceeds from these sales go to support the programs and services of CSBPS including:

• Information and referral
• A low vision clinic
• One-on-one counseling
• Training in safe travel and independent living
• Personal service volunteers

CSBPS has a CCTV rental program and coordinates consignment sales of used CCTVs, as well as other low vision devices. The availability of units varies and is usually quite limited. Rental rates range from $30 to $70 monthly plus tax, depending on the unit. Delivery and set-up (if needed) costs are extra and varies with location. If you are interested in renting, purchasing or selling a used CCTV, please contact a CSBPS low vision specialist, at (800) 458-4888.
