The network outside the store

At a Home Depot car park in the United States, a camera can now be more than a camera. It can read a number plate, surface a vehicle to an investigator and sit inside a wider security system sold to cities, police departments, businesses and neighbourhoods. That is the business Flock Safety has built: an argument that the street, the shopfront and the roadside can become a searchable safety network.

It is also the argument now colliding with a more uncomfortable question: once a private camera network becomes useful to the state, who decides where the data travels next? Reuters reported in January that Home Depot uses Flock automated number-plate readers at stores and in car parks. The retailer said it does not grant federal law-enforcement agencies direct access.

But Reuters also reported that 404 Media had found ICE investigations using Flock data passed on by local law enforcement. That gap — between who owns a camera, who can search it and who ultimately receives a lead — is where the political story begins. Flock’s answer is governance.

The company says its customers control access, every search is tied to a user and recorded, and agencies decide for themselves whether to share data with a broader network. That may be a meaningful safeguard. It is also a reminder that the decisive choice is often not made by the camera manufacturer, but by the local institution holding the keys.

Europe is not waiting, but it is drawing different lines

The European question is not whether cameras are becoming more capable. They are. It is whether the American model of a rapidly expanding, privately supplied investigation network can survive Europe’s different rules on biometric data, public authority and proportionality.

Britain offers the most operationally advanced contrast. The Home Office says police carry out more than 25,000 retrospective facial-image searches every month. It says thirteen forces had used, or were using, live facial recognition by November 2025, and that London deployments between January 2024 and September 2025 led to more than 1,300 arrests.

The government also says a national evaluation of facial recognition’s effects on policing and crime outcomes is still under way. That last sentence matters as much as the arrest figure. An arrest total can show that a tool generated leads.

It cannot, on its own, show whether a city became safer, whether crime simply moved elsewhere, or whether another policing tactic would have produced the same result. The evidence on ordinary CCTV is a useful corrective to the pitch that more cameras automatically mean less crime. A Campbell Collaboration review of 44 evaluations found a modest effect on property crime, no effect on violent crime and its clearest results in car parks — usually alongside guards, lighting and other preventive measures.

Cameras can work in a system. The research is much less supportive of treating them as the system.

A continent of different guardrails

Europe’s legal map is uneven by design. The European Commission describes the AI Act as the bloc’s legal framework for artificial intelligence. In the Netherlands, the data-protection authority says organisational use of cameras with facial recognition is almost always prohibited, subject to narrow exceptions.

The UK, outside the EU, is moving in the other direction: its government says it wants a more consistent framework that lets police expand facial-recognition use while preserving safeguards. This is why a straight Flock-versus-Europe comparison misses the point. Europe already has the suppliers: Axis sells object analytics for cameras; Milestone sells video-management and analytics software; Veesion sells retail video analysis.

What Europe has not accepted is one answer to the harder question of how data should move between a shop, a police force, a city and a national system. The coming contest is not camera versus no camera. It is whether a society can build rules that make the useful, narrow cases legible — finding a wanted violent offender, protecting a vulnerable missing child, reducing theft in a car park — without quietly creating an infrastructure that knows too much about everyone else.

Flock’s rise makes that choice feel immediate. Europe’s response will decide whether the next surveillance network is built around convenience, constraint or something more durable: public trust.
