Use a projector screen to display items from your document camera.
Document cameras let you display books, letter-size charts and other documents onto a screen without the document having to be transparent like with a overhead projector. The camera, a video camera similar to a camcorder, is vertical and was first developed to train soldiers during World War II. The devices are found in schools, universities, courtrooms and meeting spaces. The devices can also interface with computers and video recording devices for storing the document information.
Displays a Variety of Items
Document cameras are capable of displaying a variety of items including 3D objects like cubes, maps, products and other physical items as well as handwritten documents, slides, photos, books, transparencies, opaque materials and computer printouts. If the item fits the camera's display platform, it is displayable on the screen.
Capable of Saving
The devices interface with not only computers, but also with any video recording device so your presentation can be saved and shared with others not attending the meeting, conference or lecture. This benefit allows someone to play the presentation back and see what documents or items were discussed.
Color Black/White
Document cameras display black-and-white and color images on a display or projector screen.
Adjustable
The camera is fully adjustable including the focus mechanism and the zoom control for moving closer to the document or item on the display platform.
Long Lasting Ease of Use
Document cameras contain long-lasting components including the fluorescent light assembly. The devices are not hard to use and don't require a computer program or network in order to access the device's controls. Even students or presentation attendees can operate the devices.
Expensive
Document cameras are expensive, with the cheapest models costing cost more than stand-alone overhead transparency projectors.
Require a Projection Screen or Television
The document camera is a stand-alone device that doesn't include a projection screen. Any projection screen will work with the device--including a white sheet--or connect the camera to a television set or other video component for broadcasting your presentation.
Harder to Find
Overhead projectors are more common than document cameras and readily available from a number of vendors and outlets. Document cameras are available mostly from vendors who sell computer devices and educational equipment.
Limits on Page Size
The document camera's display range is limited to approximately a 8 #xBD;-inch by 11-inch page size. Larger items must be placed on the display platform and moved around as the the camera's zoom-in feature is activated to display the entire item.
