Samsung's SDP-760 HD Digital Presenter, also known as a document camera, intended for classrooms and meeting rooms and similar environments, connects right into a digital blackboard, a projector, or a TV (or any other display with a VGA or RCA connection), and outputs to it an HD image of whatever you put in front or under the camera eye, whether a classroom document or a business document, or any alike item, or a person. If a document, for example, any markings you make on it, such as with a red marker, will project live to the connected display, as long as the camera eye remains on the document, and if it doesn't, then just move it back onto the document once you've made your markings. The neck of the camera is adjustable to capture from almost any angle. The sensor is a 3 megapixel Progressive Scan CMOS, and the lens can zoom in up to 8 times, helpful for seeing drawings and diagrams up close. (With the optional addition of a Microscope Adapter, you can zoom in much more, helpful for very detailed drawings and diagrams.)
Furthermore, while connected to a big display and carrying out your presentation, you can connect at the same time to a computer by a USB cable, and via the included software you can record onto the computer whatever your audience sees on the big screen. Afterwards, you can post the recordings online for those who missed the presentation or use them for other purposes, such as self-reviews. The camera is compatible with Macs and with PCs and it saves recordings as AVI files. The included software, other than a recording function, also offers a few effects that you can apply to your presentations, namely, masks, freeze-frames and image rotation.
The camera is very compact and it folds to be very convenient to carry. It comes to you ready for use with a VGA cable, a USB cable, and a power adapter.
