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.
