In recent years, with the rapid development of IP networks, the video surveillance industry has also entered the era of full networking. The video surveillance industry in the networked era is gradually showing the characteristics of the IT industry. As the core product of networked surveillance, NVR (Network Video Recorder) has essentially become an IT product. The main function of NVR is to receive the digital video stream transmitted by IPC (network camera), DVS (video encoder) and other equipment through the network, and store and manage it.
To put it simply: NVR (NETWORK VIDEO RECORDER), also known as network video recorder, is a type of video recording equipment that is used in conjunction with a network camera or video encoder to realize the recording of digital video transmitted over the network. Its core value lies in video middleware. Through video middleware, it is widely compatible with the encoding formats of different digital devices of various manufacturers, so as to realize the advantages of distributed architecture and componentized access brought by networking.
