The Vaddio 999-6907-000 WallVIEW CCU HD-18 is built around the ClearVIEW CCU HD-18 high definition pan/tilt/zoom camera, with a 1/3", 1.3 megapixel CCD imaging sensor, a glass multi-element wide dynamic zoom lens (18x optical), a tally light and a 1.8-lux rating, providing superior images in a wide range of high-definition video applications. The WallVIEW CCU HD-18 enables the adjustment of color, gain, pedestal, gamma and iris functions on the camera with the turn of a knob. These controls allow the camera to deliver a more accurate representation of the image that is being captured and color match and shade multiple cameras. User-defined adjustments may be stored using two Scene buttons. High speed differential signaling is used with the WallVIEW CCU HD-18 to deliver high quality HD and SD video over standard Cat. 5 cabling. Adjustments allow the video to be extended up to 500 feet from the Quick-Connect CCU with virtually no loss in video quality or additional latency.
