Closed-circuit televisions (CCTVs) are now more commonly referred to as video magnifiers or electronic magnifiers and come in a variety of designs. The classic desktop magnifier can be compared to a microfiche machine often seen in a public library; an object (the film) rests under a camera and an enlarged image of it appears on a monitor above. Video magnifiers act similarly to other low vision devices in that they enlarge the image of an object so that it is easier to see.
