All notes

Everything here, in eight sections. If a demonstration was impressive, start with the limits. If something involving identification or inference has been proposed, start with the boundary section.

All 50 notes

Grouped by section, each appearing once. The label above each note says what kind it is.

Foundations

6 notes

Three capabilities share the name and differ enormously in what they do and what the law permits. Separating them is the first task, and it decides everything after.

What it cannot see

5 notes

An average accuracy figure conceals that the errors are not evenly distributed. Plus the physical conditions that no software fixes, and the drift that happens quietly.

Where it works

5 notes

The deployments with a real record, most of which point cameras at objects rather than people, and the ones where a supplement is substituted for the control that should have been installed.

The boundary

6 notes

The section this subject requires. What should not be built, why the objections converge rather than trading off, and what to offer instead when the request is reasonable underneath.

Regulation

5 notes

The prohibitions are already in force. What each tier requires, why consent does not work in a workplace, and the records that cannot be reconstructed afterwards.

Building and evaluating

9 notes

Camera placement is the highest-return investment and appears in no vendor proposal. Plus the evaluation that means something and the threshold decision that is a business call, not a setting.

Running it

9 notes

Where the analysis runs determines what leaves the building. Plus the alert arithmetic that decides whether anyone reads the output, and the systems nobody remembered to turn off.

Reference

5 notes

The boundary stated plainly: the questions a camera cannot answer, the asks that should be declined, and a description of the end state to measure a proposal against.
