CCTV Storage Calculator
Estimate recording storage from camera count, bitrate, recording hours and retention.
Use figures from your own operation. The result is an indicative planning model, not a quotation or guarantee.
Your result
How this works
Storage in bytes = cameras × Mbps × 1,000,000 ÷ 8 × recording seconds. Results show decimal TB and include optional planning headroom.
Hypothetical worked example
Sixteen cameras at 4 Mbps recording continuously generate roughly 691 GB per day before filesystem, redundancy and export headroom.
How to interpret the result
Use the output to compare scenarios and expose the assumptions that have the greatest effect. Validate the figures with process owners, finance and technical teams before making a purchasing decision.
Assumptions and limitations
- Inputs are supplied by you and are not verified by REVTEK.
- Taxes, financing, supplier terms and operational variation may be excluded.
- An estimate should be tested with measured data and sensitivity scenarios.
Common mistakes
- Using best-case assumptions only
- Ignoring support, adoption and exception handling
- Treating a calculated result as a supplier commitment
Practical next steps
- Confirm input figures with accountable owners.
- Run conservative, expected and optimistic scenarios.
- Document exclusions and review the estimate after implementation.
