Video magnifiers (CCTV's) give higher magnification than is possible with
a magnifying lens. One can sit comfortably in front of a monitor or TV
screen and, with the aid of a powerful lens in a camera, read text up
to 45 times larger or even more.
In some units the camera can be held in the hand like the “mouse“
of a computer, and guided across the page. In other units, the camera
is mounted on a stand, above a moveable platform that conveys the text
back and forth at a speed controlled by the user. The latter units are
generally easier to use and the user can perform some tasks under the
camera - particularly writing.
Most of these units can be obtained with a colour camera. Almost all have
a reverse image capability - black letters on a white background or white
letters on a black background.
In some models, the image can be made to appear in a type of "goggles",
making the unit truly portable A rechargeable battery provides the power.
We have pictured a few models, please call for further details.
