A Network Video Recorder (NVR) is a centralized system that captures, stores, and manages video feeds from multiple IP cameras. Unlike DVRs that work with analog cameras, NVRs operate over IP networks, enabling scalability, remote access, and integration with other security systems. NVRs handle recording, playback, searching, and export of video footage for forensic analysis. NVRs are the backbone of modern surveillance: offices, factories, cities, and critical infrastructure rely on NVRs for security, compliance, and incident investigation. Enterprise NVRs manage hundreds of cameras and store months of video.
