Make almost any wall – or even tabletop – interactive with the sleek and powerful BrightLink 485Wi projector. This high-performance, network-ready projector and interactive pens integrate interactive functionality into one machine without the constraints or expense of an interactive whiteboard. Annotate from any source – directly on projected images sent over the network or on content from DVD/Blu-ray players and document cameras – without the use of a computer. Plus, with dual pen support, two users can write simultaneously, making it easier than ever to actively engage your students in the curriculum. And, setup is easy with auto calibration and no PC driver to install2. The impressive ultra-short-throw projection of BrightLink 485Wi means you can project large, interactive, WXGA images up to 100″ without shadow interference.
