CHAPTER 8

Uses and Phased Introduction

The same streetlight units can serve many uses. But the functions required, and the difficulty of social acceptance, differ greatly by use. We therefore propose adding uses step by step.

Main uses

Use	How it works	Additional burden	Social acceptability
Watching over children (Bluetooth)	Streetlights detect a smartphone or small tag carried by a child and record its location	Very small	High; based on consent of the child and parents
After-the-fact tracking (basic function)	After an incident or disappearance, people follow images camera by camera	As estimated on this site	To be confirmed in pilots
Anomaly detection	On-device AI continuously detects dangerous situations and sends alerts	More power and computation	The most difficult
Behaviour-pattern analysis	Trends analysed from accumulated information	Large	Requires careful debate

Watching over children is the ideal entry point

Bluetooth-based watching-over rests on consent, so it meets little opposition and costs almost nothing extra. It also improves the accuracy of camera tracking, because "the child carrying this tag" can be linked to the images even in a crowd.

Anomaly detection is where VRAIO applies most directly

Anomaly detection, with AI judging continuously, is a difficult use to accept. On the other hand, it is "AI output" in the purest sense: what the AI detected, and whom it notified, can all be recorded and audited by VRAIO. We envisage adding it as the final stage, after society has decided.

Build in hardware headroom from the start

Units on top of streetlights are not easily replaced. We therefore recommend installing AI-processing parts and Bluetooth receivers from the start, and enabling functions step by step through software updates as society agrees. The initial cost rises slightly, but this is cheaper than refitting each time a use is added.

How to run a pilot

The first step is a pilot of limited scope — for example, the routes to one primary school, or a limited residential district.

Limits: limited area, period and purpose.
Explanation and consultation: advance explanation to residents and consultation with the community.
Independent review: independent ethical review.
Audit and complaints: operations are audited, and a complaints desk is set up.
Shutdown criteria: criteria for stopping if problems arise are set in advance.

What pilots should verify

Effects on safety (deterring crime, finding missing persons sooner)
Accuracy of tracking and detection (mix-ups, misses, performance at night and in crowds)
Privacy risks, and how effectively VRAIO governs them
How residents feel (changes in reassurance and anxiety)
Durability and reliability of the equipment (direct sunlight, heat, wind and rain)
Total cost including installation, communication, maintenance, operation and auditing
