An NVR records video from network cameras, while a DVR is generally associated with analogue camera signals processed at the recorder. The right platform depends on the existing cameras, desired quality, network design and future expansion. The design should consider camera count, resolution, frame rate, retention period, storage, export needs, user permissions, remote access, alerts, analytics, display outputs and backup or redundancy expectations.
