Document camera
A document camera, also known as a visual presenter, visualizer, digital overhead, docu-cam, or simply a doc-cam, is a high-resolution image capturing device used to display objects in real-time to a large audience, such as in a classroom or lecture hall. It can also function as an alternative to a traditional image scanner for digitizing documents for archival or digital storage. The camera is typically mounted on an adjustable arm, allowing it to be positioned over a document or an object. It connects to a projector or a similar video display system, enabling the presenter to display text, images, or objects to the audience. Larger objects can be placed in front of the camera, which can then be rotated as needed.
