Growing Backlash To Flock Safety Cameras As US Surveillance Network Spreads

HOUSTON — Four surveillance cameras were cut down in Houston’s Old Braeswood neighbourhood in late July, an act of vandalism that has become part of a larger dispute over the expanding use of automated license-plate readers across the United States.

A Flock Safety camera was mounted on a metal pole with a solar panel. The equipment was found on the ground following the attack. Some of the cameras had signs indicating that the area was under 24-hour video surveillance.

As resistance to Flock's expanding surveillance network has mounted, similar incidents have been reported in other states, including Minnesota, California and Georgia.

Founded in 2017, Flock Safety makes automated license-plate reader systems that take pictures of passing vehicles and record information such as licence plates and vehicle characteristics. Law enforcement agencies, schools, businesses and communities use its technology.

The company says its systems help investigators solve crimes and find missing people. Its latest impact report notes that in 2025, its tech aided in more than 1 million investigations and contributed to approximately 20% of closed cases in regions where it operates. The figures are from the company’s own survey and analysis.

But privacy advocates say the technology creates an extensive record of the movements of vehicles and can allow law enforcement agencies to search data collected far outside their jurisdictions.

One of the major differences between Flock’s system and older licence plate readers is the nationwide connectivity.

An ever-expanding surveillance network

Agencies joining Flock's network can search cameras operated by other agencies in the network, potentially broadening an investigation far beyond the community where it began.

It’s difficult to know just how big Flock’s national network is, because the company doesn’t release a full public list of every camera.

Flock boasts more than 6,000 community partnerships and a vast national network of licence-plate readers. Recent reports have also documented rapid expansion of the technology across Texas and other states.

In Houston, records obtained by the BBC reveal how access to the network can extend beyond cameras operated by one agency. For example, the Houston METRO Transit Authority owns 35 cameras but has access to thousands of devices elsewhere in the Flock network, according to documents cited in the original report.

Privacy advocates say the ability to do cross-jurisdictional searches changes the nature of the technology.

Christopher Rivera of the Texas Civil Rights Project has argued that such databases can reveal patterns in people’s daily lives, including routes to work, schools and places of worship.

It’s not simply that a camera picks up a vehicle. Repeated observations pooled across locations can provide investigators information about where someone has travelled.

Safeguards questions raised by misuse

Concerns grew after a string of incidents in which law enforcement officers misused surveillance systems for purposes other than legitimate investigations.

A Kentucky police officer is accused of using Flock’s system to track an ex-girlfriend thousands of times. The case pointed to the need for more controls over individual searches.

Since then, Flock has announced additional safeguards, including increased search auditing and monitoring, multifactor authentication requirements, and a reduction in its recommended default data-retention period from 30 days to seven days. “Customers also have more control over how data is shared,” the company says.

Another case in Texas has become the focus of a national debate.

In 2025, a Johnson County sheriff’s deputy used the national Flock network in an investigation of a woman suspected of having an abortion. Court filings and advocacy documents show that investigators searched more than 83,000 cameras. The woman was located, but prosecutors determined not to file charges after a medical examiner found the biological material to be a blood clot, not a foetus.

The episode has become a poster child for civil liberties groups who say automated licence-plate databases can be used for investigations far beyond their original public-safety purpose.

The technology is more than licence plates.

Flock’s newer systems can identify vehicles based on more than just a licence plate, including the make, model, colour and other visible features. In Texas, people have reported searches using combinations such as vehicle colour, model and accessories.

Flock says its platform helps law enforcement investigate crimes and gives them auditing and privacy controls. The company also states that it does not use facial recognition in its Flock licence-plate-reader system.

That distinction is important because other law enforcement agencies have their own facial recognition systems.

In Harris County, Texas, records obtained by the BBC show the Sheriff's Office has used Clearview AI, a facial-recognition company that uses images scraped from publicly available online sources.

Clearview has been subject to regulatory action for its collection and use of personal images. The UK's Information Commissioner's Office originally fined the company £7.5 million in 2022 over the scraping of images of UK residents. The legal fight dragged on, with the Upper Tribunal in the UK in 2025 upholding a number of ICO’s appeal grounds around the company’s processing of personal information.

A battle over privacy and safety

The Flock controversy raises a bigger question for communities across the U.S.: How much surveillance should police be allowed to use in the name of public safety, and how should that access be limited?

Law enforcement agencies and other Flock customers say the technology has helped them in investigations to identify vehicles, recover stolen property and locate missing people. Flock’s own impact report for 2025 says its technology assisted in more than 1 million investigations and helped locate more than 10,000 missing persons.

But civil liberties advocates say effectiveness does not answer questions of access, retention, data sharing and oversight.

The backlash has already seeped into policy discussions. Some communities and state officials in Texas are considering whether to cut back or end the technology, and some jurisdictions have cancelled their contracts. New reporting also shows that the state’s Flock network remains extensive despite the controversy.

The cameras have become a visible symbol of the debate for residents. People are learning more about how the systems work and how widely their data can be searched, so what once attracted little attention is now coming under increasing scrutiny.

The vandalised cameras in Houston are thus more than just broken equipment. They are a sign of escalating conflict over the balance between public safety, privacy and the growing role of artificial intelligence in American surveillance.
