"Ultra 8 is the HoverCam you can use without a computer. Ultra 8 is a document camera with HDMI, VGA and SuperSpeed USB 3.0 video outputs with 8MP resolution and 60 frames/sec speed. Connect it directly to a monitor or projector without a computer using an HDMI or VGA cable, or, use it with a computer with the USB cable to display live HD video for instruction, training and presentations. Scanning, taking 8MP snapshots and recording full-motion no-lag HD video over USB directly to the computer is easy. Or, take snap shots and record video directly to a SD card. An LCD preview monitor is also used for touch screen control. Calling the HoverCam a document camera doesn't do it justice - it does so much more. It's also a scanner, HD webcam and video recorder."
