The latest document camera is the ActiView 522 from Promethean, which ups the ante with HD operations. The system has a 6X optical zoom, 30 frame-per-second video and a pair of LED lights on flexible gooseneck arms. On top of VGA and Composite video ports, the ActiView 522 has an HDMI connection, enough storage space for 240 high quality images and a great new feature if the device will be used by different teachers throughput the day: It can automatically erase any new items when the system is turned off.
