Network Video Recorder (Network Video Recorder referred NVR) is to receive from the network cameras (IPC), network dome camera (IP DOME) is sent to the audio and video data over the network, real-time preview, data storage, data transfer, and remote on-demand capabilities. Also for image motion detection, can control PTZ through a decoder can transmit images over the network and control signals. Compared with the DVR (Digital Video Recorder), with simple wiring that can support high definition (4K,1080P, 720P) and other advantages.
The company’s network video recording system software support for embedded network video recorders is to build a security monitoring system designed and developed a series of dedicated embedded network video recorders. Mainly applied to the image and voice for a long time video, audio, remote monitoring, and control applications. It uses an integrated design, the single-board integrated audio and video decoding, storage, network transmission, multiple PTZ control, and other functions, to ensure the system’s high integration and high reliability. It offers a variety of network interfaces, using TCP/IP and other protocols, enabling connection with LAN, WAN, allowing users wherever they can be accessed through a network connection, to achieve the monitored area monitoring and recording. Simple system operation, a wide range of applications.
