About the project

Make the system math inspectable.

Camera Ledger is an independent planning-tool publisher for people sizing small and mid-sized network-camera systems.

Why this site exists

Storage vendors make storage calculators. Camera vendors make camera design tools. Ecosystem vendors make compatibility selectors. Each can be useful, but a planner still has to carry assumptions from one tab to the next. Camera Ledger keeps the common constraints in one neutral worksheet and shows the arithmetic behind the answer.

The tools are useful without advertisements, accounts, or product sales. Project inputs are calculated in the browser. We do not accept payment to change a formula or hide a limitation.

How we publish

  • Prefer a user-entered device specification over an invented resolution preset.
  • Separate raw video, overhead, protection, and free-space reserve.
  • Link to primary standards pages and technical documentation where accessible.
  • State where geometry or arithmetic stops and real commissioning begins.
  • Correct material changes and show the review date on guides.

Ownership and contact

Camera Ledger is the editorial owner and operator of this site. The project is currently founder-operated. Questions, corrections, and source suggestions can be sent to hello@tinytoollab.com. This is the temporary owner contact for the initial launch.

Start with the worksheet

Model camera groups once, then check storage, bandwidth, power, and channel headroom together.
