The QPC 20 Portable Visualizer from QOMO features a lightweight, foldable body and easy plug-and-play USB connection for presenters on the go. A five-megapixel camera offers high-definition image capture, and built-in LED lighting offers extra illumination. Record both video and audio for later viewing, and manipulate the image with a variety of functions, including rotation and white balance. Includes AC adapter, capture software and viewing pad. The QOMO RF Wireless Interactive Tablet uses the same technology as long-range wireless networking providers, so you can use multiple devices without crossover interference. Access your computer from anywhere in your classroom to annotate files and images while you give presentations. Pen uses standard AAA batteries (not included) and automatically shuts off to save battery life. The tablet battery is good for up to 25 hours of use.
