Closed-Circuit
Televisions (CCTVs) |

A Closed Circuit Television (CCTV) is an electronic magnification
reading system that enables visually impaired users to continue
reading a variety of materials and with some models also facilitates
handwriting. A CCTV uses a stand-mounted or hand-held video camera
to project a magnified image of user-selected printed matter onto
a dedicated video monitor or a TV screen.
Stand-mounted CCTVs
To use a stand-mounted CCTV, you place the reading material flat
on the unit's viewing surface (like a small desktop) under the
camera. Stand-mounted units usually feature a moveable viewing
surface 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
writing because your hand can easily fit under the camera on the
viewing surface.
Hand-held CCTVs
Hand-held units 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 surface. 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 head-mounted display. These
units can magnify almost anything within reach of the camera,
including labels on food and medicine. Some hand-held cameras
include, as an accessory, a fixed stand.
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).
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.
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.
As of 2007, CCTV systems range in price from $305 to $4900 (plus
tax), and include delivery and set-up within our primary,
tri-county service area (King, Snohomish and Skagit Counties of
Washington State) and other nearby cities like Tacoma, Bremerton,
and Bainbridge Island. CSBPS accepts cash, checks, Visa or MasterCard
for CCTV sales. 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.
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 CSBPS at (800) 458-4888.

To fully understand the potential of these tools, a one-on-one
discussion is the surest way to best answer your questions about
CCTVs. At CSBPS, our focus is not on sales, but on making sure
you get the most appropriate devices that will support you in
meeting your needs.
