Set up is simple with this one cable viewer. Simply plug the document camera into the USB port on your computer, launch the included Applied Vision Software, and you’re all set to start. There is no electrical plug, because the unit is powered by the computer and no light bulbs are used, so there is no replacement required for maintenance. You can also place the unit close to your computer, because of its small 7" x 7" base. The viewer features a 1280 x 1040 SXGA resolution auto focus that provides a clear, sharp image ideal for use with interactive whiteboard technology. Use the Applied Vision for image capture, movies, time-lapse, rotate, brightness, contrast and much more. PC, Mac, and Linux compatible. Made in the USA. Includes three-year manufacturer warranty.
