A document camera is a digital camera mounted on an arm. The camera has zoom and focus controls, and can be pointed at a flat object (e.g., a magazine) or three-dimensional one, such as the flower in the photo. Many cameras can also be pointed away from the stand. This kind of device typically sends an image to a projector or display monitor, but it can also feed directly into a computer. This type of device is also known as an image presenter, visual presenter, digital visualizer, digital overhead, docucam, or Elmo. Many classrooms at Notre Dame are equipped with document cameras like the Wolfvision unit shown here.
