This is a research-stage concept. A prototype was operated in field trials in Kiryu City, Japan; the integrated system at streetlight scale has not yet been built and will be tested in pilot demonstrations.

Streets where children can play outside safely —
starting from the streetlights.

FMPS (Fully Monitored Public Space) is a concept for public-safety infrastructure: inexpensive cameras built into existing streetlights, so that people's movements in public space can be followed without gaps. Privacy is protected not by restricting measurement but by governing how information is released, through VRAIO (Verifiable Record of AI Output).

The public space FMPS aims for

Key points

1. If routes are covered in public space, a person's movement never breaks off. Everything outside public space is private property, so if a person disappears, we know which property they entered.
2. Streetlights already cover public space. All that is needed is to add inexpensive, smartphone-grade parts.
3. Footage is not streamed. It is stored encrypted at each streetlight, and only when an incident or a disappearance occurs are the necessary few seconds retrieved, camera by camera.
4. Technology and cost are no longer the barrier. The largest remaining barrier is concern about privacy.
5. VRAIO directly addresses what that concern is really about: misuse of information. An independent Recorder records who retrieved what, and for what purpose, and every retrieval is subject to audit and sanctions.

The figures are estimates. Assumptions and calculations are in 5. FMPS in Numbers.

Where to start

• For residents: What if one day your child does not come home? A concrete example of what FMPS does — and does not do. Then read Chapters 6 and 7.
• For local governments and police: How it works, the numbers, phased introduction, and operation. See Chapters 4, 5, 8 and 9.
• For companies: Lighting, cameras, telecommunications, AI, security, maintenance and auditing — for those considering joining a new public-infrastructure industry.
