Dahua SD49825GB-HNR 8MP 25x Starlight IR Network PTZ Camera
Product Description
The camera with powerful optical zoom and precise pan/tilt/zoom adjustment is designed to solve long-distance video surveillance problems for outdoor use. It is a universal solution for obtaining detailed video images over long distances. Equipped with infrared illumination and Starlight technology, this camera performs excellently in dark and low-light conditions and provides clear, high-quality images. One of the most important features of this camera is Dahua Face Detection technology. Using a deep learning algorithm, the camera can recognize faces in the resulting images. It supports face tracking, capturing and selecting the best face image, providing valuable images for identification and analysis purposes. In addition, the camera is equipped with Dahua Smart Motion Detection technology, which uses intelligent algorithms to classify alarm targets when motion is detected. This technology screens non-target objects such as small and large animals, minimizing false alarms and ensuring that alerts are timely and accurate. When used in conjunction with an AI NVR, the camera provides access to Quick Pick technology. This function simplifies the process of searching and identifying people and vehicles using video recordings of events obtained as a result of motion detection. It prioritizes the most relevant objects, simplifying the process of identifying important events.
