Document cameras offer a number of different features, and they can vary substantially based on the model chosen. Most of the models available today will come with a remote control to make operation simple. In addition to being able to connect to projector screens, it is also possible to utilize LED and LCD monitors with them.
The document camera is able to magnify and project images placed beneath the camera onto a screen that the audience will be able to see. The presenter can place nearly any type of object below the camera, and it will show up on the screen. The camera takes the picture of the object, which then turns it into a live picture. The document camera is the replacement of the older model overhead projectors. Thanks to the quality of the cameras in these devices, they are able to present excellent images. In some instances, they will connect to an interactive whiteboard rather than an actual screen.
