Multiply the average video bitrate per camera in Mbps by 0.45, recording hours per day, retention days, and camera count. Add capacity headroom, then validate the result using real recordings and the recorder manufacturer's drive limits.

Video bitrate changes with camera settings, frame rate, codec, movement, lighting, and scene detail. Recorder overhead and retention behavior also vary, so use measured bitrates when available and test a representative recording period.

Camera-to-NVR recording on the same site generally uses the local network rather than the internet connection. Cloud recording and remote viewing do use internet upload and download capacity.
