A document camera, also known as a digital visual presenter or visualizer, is essentially a camera that is elevated on a stand, pointing directly downward, like the old overhead projector. Whatever is placed beneath the camera's lens is displayed in exponential size on a computer, LCD monitor or projection screen. The document camera is an interactive tool that can enhance teaching, training, lecturing and other educational presentations.
Adjustable Viewing Capability
A document camera has a head and arm that rotate so that you can easily view a two- or three-dimensional object from different angles. Most document cameras feature a camera lens that you can align to the eyepiece of a microscope without an optical adapter.

To view objects from almost any angle, look for a document camera with a curved arm that rotates 180 degrees.
Detailed Imagery
Document cameras have a digital zoom that captures the detail of both static and moving objects that would otherwise be unobservable to a large audience. Document cameras that feature at least a 5.2x optical and an 8x digital zoom lens can capture detail and display it on a broad screen device for general viewing.
Presentation Stages
The presentation stage is the platform attached to the bottom of the camera. This platform is where you place objects you wish to magnify and display. Some document cameras feature a removable presentation stage, which allows you to remove the bottom platform, or stage, when you want to view larger objects like people, cars or architecture. Other models feature a stationary presentation stage that limits the viewing area to a 12-by-16-inch platform. Models with a stationary stage are generally better for viewing smaller objects like text pages and other objects that do not exceed the perimeters of the viewing area.
