Mapping
mapped · no interpretation or interpolation added by this passport

Claim 3 clm-c2840d4e5f7afd76 descriptive

Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The release states that video footage is processed in real time and immediately discarded, with only anonymous data retained, and that faces and license plates are deliberately obscured in any footage.
Caveat
This is the operator's description of its own system. No party outside the city has audited the deletion behaviour.

Claim 4 clm-1e7fc8036d471250 quantitative
A separate city testbed pilot ran 12 VivaCity sensors across four boroughs from July 2023 to April 2024, under the same deletion rule

Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The NYC Smart City Testbed page records 12 computer-vision sensors installed across four boroughs, a pilot period of July 2023 to April 2024, VivaCity as the supplier, and that video frames are deleted nearly instantaneously with only anonymous features stored.
Caveat
The testbed pilot and the DOT programme are described on separate pages with different location counts. No source states that one became the other, and this entry does not claim it.

Awaiting operator and domain-expert review; publication of this revision implies neither.

Open the recorded source note

Undated programme page. Documents a separate, earlier testbed pilot: 12 VivaCity sensors in four boroughs, July 2023 to April 2024. Not the same deployment as the DOT programme, and kept apart in the entry for that reason.

Known limits of this passport
  • Publisher names and source languages have not yet been classified; domains are recorded without guessing.
  • Existing source notes are descriptive locators, not page- or paragraph-exact citations.
  • A missing archive, publication date or content hash is shown as null rather than inferred.
  • The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
