CCTV Storage Calculator

Estimate CCTV storage from camera count, average bitrate, recording schedule, retention and overhead using a transparent formula.

PRELIMINARY ESTIMATE—

Enter assumptions and calculate.

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.
