The first conference room and boardroom installation projector available in the market with a built-in motion-sensitive, anti-theft alarm for investment-protection, the XL5900U/LU Natural Color Matrix offers vibrant colors, 4000 ANSI lumens of brightness and installation flexibility of horizontal and vertical lens shift. The alarm, built into the connector panel cover, is set manually by a key. If someone moves the projector, a loud and annoying 120-decibel high pitch alarm will sound and alert movement of the projector.
