Formula and limitations
cameras × Mbps ÷ 8 × 3600 × hours × days × (1 + overhead)The result is decimal terabytes (1 TB = 1,000,000,000,000 bytes). Motion recording, codec behaviour, scene complexity, audio, redundancy, filesystem reserve and vendor implementation can materially change actual requirements.
