- Document cameras or visualizers read any 3D object or text and then use a projector or display to visualize it for a group of spectators. Most, often, they are placed on a desk. The scanned object or document is laid on a pad and a projector sends the image on a screen or interactive board.
- Most of document cameras have a flexible arm allowing for a swivelling motion of their head, and a zoom objective in order to enlarge the required part of the object. Other options include document cameras installed under the ceiling, which are appropriate for reading of larger objects.
