A Network Video Recorder (NVR) is a specialized device or software system used in modern video surveillance to store, manage, and analyze footage from IP (Internet Protocol) cameras. Unlike traditional DVRs (Digital Video Recorders), which work with analog cameras, NVRs are designed for IP-based systems, offering higher flexibility, scalability, and advanced features. NVRs are central to smart security setups in homes, businesses, and public spaces.
