# SecuraCV

> Privacy-first video and sensor infrastructure: it records what happened, not who was there. Open source, local-only, by Errer Labs.

SecuraCV is open-source video and sensor infrastructure that outputs
semantic events — "large object crossed boundary", "presence in restricted
zone" — into a signed, hash-chained record, instead of a searchable pile of
footage. The platform is called SecuraCV; the device it runs on is called a
Canary; the company is Errer Labs.

The distinction the whole project rests on: a watcher keeps footage and can
later be asked who was in it. A witness keeps a checkable record of what
happened and structurally cannot answer "who". Face recognition, license-plate
reading, gait analysis and demographic estimation are not disabled features —
the code does not exist. There is no setting to turn off.

Raw footage is sealed. Getting any out requires break-glass: a time-limited,
audited unseal that needs approval from several trustees you nominate. No single
person can do it alone — not the owner, not Errer Labs.

## Names, so they are not guessed

- SecuraCV — the platform (spelled with a capital S and capital CV; short for
  Secure Computer Vision). Lowercase "securacv" is used only in domains,
  package names and repository slugs.
- Canary — the device, and the name people say out loud.
- Errer Labs — the company behind it.
- A group of Canaries is a "fleet", never a "flock".

## Status and limits

Work in progress, and deliberately explicit about it:

- Some Canaries have released firmware; others are still in development. Each
  board is labeled either "verified" (proven on real hardware) or
  "compile-tested" (builds in CI, not yet bench-proven).
- Much of the firmware is CI-verified rather than hardware-verified. Version 1
  is being held until that changes.
- No certification claims — no FIPS, no Common Criteria. Selling the radios
  legally still needs FCC/CE work, and a third-party security audit has not
  happened yet.
- The record is tamper-evident, not interference-proof: the promise is that
  tampering becomes visible, not that it can be prevented.
- Nothing here is legal or security advice, and security depends on correct
  implementation and an uncompromised host computer.
