NETWORK CAMERA SYSTEM WITH REAL-TIME PAN/TILT/ZOOM CONTROL CAPABILITY USING HARDWARE MPEG4 CODEC AND V2OIP

摘要

Stores the taken image in real time, and transmits and hardware MPEG4 codec and V2OIP based network camera surveillance system and a digital video recorder using the same for the pan / tilt / zoom control of the camera as possible in real time from a remote location is disclosed. The P / T / Z drive unit, the camera module, an audio codec, a memory, hardware MPEG4 codec, a network controller, the network camera system, including a central processing unit and remote terminal apparatus for controlling them is provided with a configuration. Inputted through an input through the camera module, video and audio codec, speech is compressed in real time by hardware MPEG4 codec. The compressed data is transmitted to the remote terminal apparatus by V2OIP protocol through the network controller, and is extended at the same time and stores the output from the remote terminal apparatus. The central processing unit in response to the control signal for the pan / tilt / zoom driving unit of the camera module received from the remote terminal apparatus controls the pan / tilt / zoom driving unit of the camera module in real-time.
