For many years, vehicles dictated city making plans in the USA.
Few may have predicted that they’d sooner or later additionally double as nodes for surveillance.
In 1000’s of cities and towns around the U.S., computerized registration code readers had been put in at main intersections, bridges and freeway off-ramps.
Those camera-based methods seize the registration code knowledge of passing automobiles, together with pictures of the car and time stamps. Extra just lately, those methods are the usage of synthetic intelligence to create an unlimited, searchable database that may be built-in with different regulation enforcement knowledge repositories.
As a pupil of generation coverage and knowledge governance, I see the growth of computerized registration code readers as a supply of deep fear. It’s taking place as executive government are searching for tactics to focus on immigrant and transgender communities, are already the usage of AI to watch protests, and are taking into account deploying AI methods for mass surveillance.
Eyes at the street
The use of cameras to trace license plates dates to the Nineteen Seventies, when the U.Okay. was once embroiled in a long-simmering war with the Irish Republican Military.
The Met, London’s police pressure, advanced a machine that used closed-circuit tv cameras to watch and file the license plates of automobiles getting into and exiting main roads.
The machine and its successors have been observed as helpful crime combating equipment. Over the following twenty years, they expanded to different towns within the U.Okay. and all over the world. In 1998, U.S. Customs and Border Coverage applied this generation. Via the twenty first century, it had began showing in towns around the U.S.
There are alternative ways for a jurisdiction to put into effect those methods, however native governments in most cases signal contracts with non-public corporations that give you the {hardware} and repair.
Those corporations ceaselessly trap government with loose trials of surveillance apparatus and guarantees of loose get right of entry to to their knowledge in ways in which bypass native oversight rules.
AI thrown into the combo
Not too long ago, AI has been integrated into those digital camera methods, considerably expanding their succeed in.
The car data that’s captured is generally saved within the cloud, developing an enormous internet of information repositories. If a digital camera collects data from a suspect’s automobile or truck – say, one additionally indexed within the Nationwide Crime Data Heart – AI can flag it and ship an speedy alert to native regulation enforcement.
Actually, that’s a promoting level of Flock Protection, some of the greatest suppliers of computerized registration code readers. The corporate makes use of infrared cameras to seize pictures of automobiles. AI then analyzes the knowledge to spot topics and temporarily alert native government.
At the floor, computerized registration code readers appear to be a logical technique to combat crime. Extra details about the whereabouts of suspects can probably lend a hand regulation enforcement. And why concern about cameras when you’re following the regulation?
A spokesperson for Flock instructed The Dialog that their generation has helped cut back crime, together with violent crime, in towns that use their cameras, comparable to San Francisco and Oakland.
However there are few peer-reviewed research on their effectiveness. Those who exist to find little proof that they’ve resulted in discounts in violent crime charges, despite the fact that they appear to be useful in fixing some crimes, like automobile thefts.
Moreover, set up and upkeep are pricey.
As an example, Johnson Town, Tennessee, signed a 10-year, US$8 million contract with Flock in 2025. Richmond, Virginia, paid over $1 million to the corporate between October 2024 and November 2025 and just lately prolonged its contract, in spite of opposition from some citizens.

Erosion of civil liberties in undeniable sight
The generation turns out to spotlight the pitfalls of what students name “technosolutionism,” the conclusion that complicated problems like crime, poverty and local weather trade will also be solved by means of generation.
Much more disquieting, to me, is the truth that those digital camera methods have created a mass location monitoring infrastructure knitted in combination by means of synthetic intelligence.
The U.S. doesn’t have a federal regulation just like the Ecu Union’s Basic Information Coverage Legislation that meaningfully limits the gathering, retention, sale or sharing of location and mobility knowledge.
Because of this, knowledge accumulated via surveillance infrastructure within the U.S. can flow into with restricted transparency or duty.
Registration number plate readers can simply be accessed or repurposed past their authentic targets of managing site visitors, allotting fines or catching fugitives. All it takes is a shift in enforcement priorities – or a brand new definition of what counts as a criminal offense – for the unique goal of those cameras to recede from view.
Civil liberties teams and virtual rights organizations had been sounding the alarm about those cameras for over a decade.
In 2013, the American Civil Liberties Union revealed a record titled “You are Being Tracked: How License Plate Readers Are Being Used To Record Americans’ Movements.” And the Digital Frontier Basis has decried them as “street-level surveillance.”
A counter-camera motion emerges
The promise of those cameras was once easy: extra knowledge, much less crime.
However what adopted has been murkier: extra knowledge, and an important growth of energy over the general public.
With out powerful felony safeguards, this information can most likely be used to focus on political opposition, facilitate discriminatory policing or kick back constitutionally safe actions.
This has already took place throughout the present management’s competitive deportation efforts. Computerized registration code reader databases have been shared with federal immigration companies to watch immigrant communities. Not too long ago, Customs and Border Coverage was once granted get right of entry to to over 80,000 Flock cameras, that have additionally been used to surveil protests.
Then there’s reproductive well being care. After the Excellent Court docket overturned Roe v. Wade in 2022, there have been fears that individuals touring throughout state traces to get an abortion may just probably be known via computerized registration code reader databases. In Texas, government accessed Flock’s surveillance knowledge as a part of an abortion investigation in 2025.
Flock instructed NPR in February 2026 that towns keep an eye on how this knowledge is shared: “Each Flock customer has sole authority over if, when, and with whom information is shared.” The corporate famous that it has made efforts to “strengthen sharing controls, oversight and audit capabilities within the system.” However NPR additionally reported that many town officers across the U.S. didn’t understand how broadly the knowledge was once being shared.
In reaction, some states have sought to keep an eye on the generation.
In the meantime, grassroots tasks comparable to DeFlock have additionally emerged.
DeFlock’s on-line platform paperwork the unfold of computerized registration code reader networks to be able to lend a hand communities face up to their deployment. The motion frames those methods now not simply as site visitors applied sciences, but in addition as linchpins of an increasing executive knowledge dragnet – person who calls for more potent democratic oversight and group consent.
This newsletter has been up to date to incorporate a commentary from Flock Protection.
