The Link 4K in Gray features auto-tracking for presentations where your subject moves around the room, great for education, how-to, and corporate environments without the need for an operator. Its wide dynamic range, 3D noise reduction, and handy Dante AV-H workflow capabilities provide a sharp, consistent image, even in low light. The camera's features include a 1/1.8" 4K CMOS 8.42MP sensor for crisp imagery. The built-in zoom lens has an optical zoom range of 20x, and you can zoom in further with up to 16x digital zoom. With 255 programmable preset positions via serial, you can set the camera to rapidly move between positions using IP, RS-232, or RS-485 with separately available controllers or by using IR control with the included remote.
