A Visualizer or sometimes known as Document Camera is an extension arm of a projection system. When the user has a physical document or object to be projected onto the screen, a visualizer can capture the document/ object and project through the projector directly, saving on the hassle of scanning of saving the contents into a computer before it can be projected.
There are generally 2 categories of visualizers:
1. Portable Digital Visualizer
- Light-weight and compact
- Quick and easy to setup
2. Station Digital Visualizer
