Camera Bitrate Storage Calculator accuracy and testing

This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.

Formula source

  • Daily GB = cameras x Mbps x hours x 3600 / 8 / 1024. Storage GB = daily GB x retention days x overhead factor.

Test cases

Default input regression check

Generated from the checked-in default inputs and calculate function.

Inputs

  • Camera Count: 4
  • Bitrate: 3 Mbps
  • Recording Hours: 12 hr/day
  • Retention: 14 days
  • Overhead Buffer: 15%

Expected outputs

  • Storage Needed: 1,018.83 GB
  • Storage Needed: 0.99 TB
  • Daily Storage: 63.28 GB/day

Known limitations

  • This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
  • Use the result as a planning estimate unless the calculator page states a stricter purpose.

Assumptions

  • Inputs are user-entered because pricing, deadlines, policies, and technical limits vary.
  • Calculations run locally in your browser and do not store passwords, incidents, network designs, or security program data.
  • This is planning math, not security assurance, legal advice, or a substitute for testing.

Unit handling

  • Camera Count accepts numeric values.
  • Bitrate accepts values in Mbps.
  • Recording Hours accepts values in hr/day.
  • Retention accepts values in days.
  • Overhead Buffer accepts values in %.
  • Storage Needed is displayed in GB.
  • Storage Needed is displayed in TB.
  • Daily Storage is displayed in GB/day.

Rounding rules

  • Number displays use up to 2 decimal places in the calculator UI.
  • Input precision follows configured step values where provided.
