A complete interactive projector solution can be created using the optional NP03Wi interactive system (dual pens) with auto calibration. With its ability to be mounted to the wall directly above the screen on which it projects, this model helps eliminate the shadows and glare typically found with standard projection systems. The UM351W projector includes a powerful 20W speaker, closed captioning and RJ-45 for remote management over a network, and its input panel includes dual HDMI, VGA and a microphone input to amplify the presenter’s voice. Ultra short throw lens (0.36:1 throw ratio) helps eliminate shadows on the screen along with projected light in the presenter’s eyes created by traditional front projection systems. Comprehensive input/output panel, including dual HDMI, VGA and a microphone input. ECO Mode technology helps extend lamp life and lowers power consumption. Horizontal & Vertical Keystone adjustment or Cornerstone Correction ensures the image will fill the screen every time. Remote monitoring and control of projector over network saves IT employee time and reduces costs related to projector operation. Optional interactive system (dual pens) allows for annotation and collaboration on a whiteboard locally or via web meetings.
