GV-IP Speed Dome (GV-QSD5731-IR) is an outdoor network PTZ camera that offers 33x optical zoom and 330x digital zoom, capable of showing smooth live view with great details. This camera can simultaneously deliver four video streams in resolutions up to 2592 x 1944 at 30 fps, which allows up to 150 m (500 ft) effective IR distance. GV-QSD5731-IR supports H.265 video codec to achieve better compression ratio while maintaining high quality pictures at reduced network bandwidths. Wide surveillance coverage is made possible with 360° endless panning and -20°~100° tilting capacity. PTZ functions such as Preset, Auto Pan, and Patrol can be programmed and activated by schedule. The GV-QSD5731-IR supports pan/tilt speeds ranging from a fast patrol of 280° per second to a slow ramble of 0.1° per second with 0.1° pan accuracy for fast and accurate tracking ability. GV-QSD5731-IR also features Servo Feedback and Electronic Image Stabilizer (EIS) technology. The Servo Feedback technology ensures the camera view returns to the previous position when encountering external force (e.g. human interference) or environmental vibration. EIS technology can effectively produce stable images by actively sensing directional movement of the images and compensating accordingly; this is particularly useful for cameras installed at places where environmental movement (e.g. strong wind, the passing-by heavy vehicles) is constant, and when high optical zoom is executed.
