Definition: A video magnifier or CCTV is a simple way of producing large text and images for people with some useful vision. Printed documents, handwritten materials or objects can be placed under a camera. The magnified image is then displayed on a monitor. They are most often used for reading, but some can also be used for writing, checking a price tag, looking at a timetable or to read a whiteboard in a classroom.
