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.
