Flock Cameras and the Surveillance Network Around Mableton
Part 1 of 2 — Watched From Every Border: Inside Mableton's Explosive Growth in AI Surveillance
By Stephanie Hanlon
Drive Veterans Memorial Highway near Maxham Road, ride past the intersection of Floyd Road and the East-West Connector, or head south on Mableton Parkway toward the Chattahoochee, and there's a good chance a Flock camera has already logged your license plate, your car's make and color, and the exact minute you passed.
According to the camera-mapping site deflocktheusa.com, there are approximately 9,929 surveillance cameras in the state of Georgia, with about 100 new cameras added each week, making it the 3rd most surveilled state in the United States.
Deflocktheusa.com places Mableton inside what they call the "inferno" zone: one of the most heavily surveilled pockets in the country, part of a broader Atlanta metro that now hosts over 5,000 Flock readers alone, plus thousands more cameras from other vendors.
Almost none of that growth is visible from the center of town. The cameras cluster along Mableton's borders — several on Veterans Memorial near Maxham Road, a gap until Lindley Middle School, nothing again until the Chattahoochee; a cluster in the new Floyd Road developments near Floyd Middle School, then nothing until Mableton Parkway and Factory Shoals Road; a dense residential cluster every hundred feet or so in Oakdale. There's nothing on Old Powder Springs Road, one camera near Fontaine before the East-West Connector. The heaviest concentrations sit along the boundaries with Smyrna, Powder Springs, and especially Vinings and Atlanta.
Cobb County Police, which currently provides law enforcement services to Mableton under an intergovernmental agreement running through May 31, 2027, confirmed it directly owns and operates approximately 40 of those cameras within city limits — part of a 182-camera network countywide. In 2019, there were only five Flock cameras tested in South Cobb.
The remaining belong to a patchwork of HOAs, businesses, and other private entities that may or may not share footage with police. Neither the city nor the county provided a total number of surveillance devices monitoring Mableton residents.
"Private cameras do not become Cobb County property simply because an owner elects to share information or access with law enforcement," Cobb Police spokesperson Sgt. Eric Smith said in a written response. Sgt. Smith drew a further distinction that residents may not realize applies to them: "It is important to distinguish Flock ALPR cameras from other types of security or surveillance cameras."
The county's 40-camera figure, he said, "should not be interpreted as an inventory of every government, business, HOA, traffic, or privately owned security camera within the city."
What the cameras are catching
Cobb Police point to a handful of documented cases as evidence the technology works.
In November 2024, a Flock camera on Mableton Parkway at Factory Shoals Road detected a vehicle tied to a Carroll County murder suspect, leading to two detentions.
On December 1, 2024, an alert on a vehicle with an active malice-murder warrant led officers to a felony stop near Mableton Parkway and Lane Drive and an arrest.
Countywide, the department says Flock generates roughly 2,000 alerts a month tied to stolen vehicles, missing persons, and wanted individuals.
Sgt. Smith also pointed to the technology's original 2019 South Cobb pilot.
During the March-through-August period before the program, the area around Six Flags averaged approximately 147 thefts from vehicles over the preceding five years.
"During the comparable 2019 period after deployment, there were 50" — a roughly 64% drop that Cobb and Flock have both cited as evidence of the cameras' impact, while Sgt. Smith stopped short of crediting the cameras alone: it's "appropriate to describe this as an observed reduction associated with the deployment area, rather than claiming that cameras alone caused every part of the decrease."
The accuracy problem
Cobb also volunteered a number worth scrutinizing: Flock's cameras have "around a 93% accuracy rate," Sgt. Smith said, adding a key caveat: "A Flock alert is an investigative lead, not probable cause by itself and not an automatic ticket." Cobb's system, he said, builds in a check on top of that — "the more meaningful safeguard is that an electronic alert must be human verified before enforcement action is taken."
That 93% accuracy figure is Flock's own company-wide claim. But when a system processes roughly 20 billion plates nationally each month, a 7% margin of error still equals over a billion misreads.
The sheer scale of that data collection is staggering: a PBS report highlighting an investigation by 404 Media found a single Flock camera captured 1.6 million photos in just 21 days.
Furthermore, department-level audits show the real-world error rate is often much higher than Flock claims.
A Los Angeles Police Department inspector general audit found roughly one in three Flock hot-list alerts it reviewed were inaccurate and the LAPD later ended its Flock contract, according to ABC.
A police department in Roseville, California, running its own review of nearly 1,500 Flock reports, found a 71% rate of character misreads — plates where the system mistook one digit or letter for another, according to the Sacramento Bee.
Those misreads aren't abstract: nationally they've led to drivers being pulled from cars at gunpoint over a "7" misread as a "2" or an "O" misread as a "0."
Locally, the pattern shows up in smaller ways too — Cobb itself acknowledged that a Mableton-area woman was ticketed in Atlanta and then ticketed again the next day in Cobb because Flock's database hadn't yet caught up to show her car had been re-registered.
That gap — a 93% vendor-reported scan accuracy versus department audits finding real-world alert error rates several times higher — is the tension sitting underneath every "this technology works" claim in this story. As a result of these and other concerns, many municipalities in the South have taken action to remove or block Flock from monitoring citizens like in Asheville, NC; Collegedale, TN; Dallas, TX; Plano, TX and others.
Georgia has its own misuse record layered on top of the error rate:
A DeKalb County Sheriff's Office sergeant arrested last month for unauthorized Flock use
Three Cherokee County officers arrested
Five Albany officers arrested
A Greene County deputy fired and arrested
Three Fayetteville officers fired
An Acworth police officer arrested and charged with felony misuse of the license plate readers
Sgt. Smith said Cobb is responding to these cases of misuse directly: the department is moving from annual to mandatory monthly audits, and its town-hall materials "emphasize that misuse is prohibited, detectable, reviewable, and subject to discipline." Asked whether public concern might slow the program down, Sgt. Smith was direct: "Cobb County Police has not announced a department-wide suspension of the Flock program."
The legal question, and who's behind the technology
The scale of what Flock can do — cross-referencing plate reads, vehicle fingerprints, and location data across a shared network — has raised a genuine, unresolved Fourth Amendment question.
In Norfolk, Virginia, a 2024 state court ruling found that warrantless Flock searches violated the Fourth Amendment, only for higher state and federal courts to later uphold the city's camera network. That legal tug-of-war is now pending before the Fourth Circuit Court of Appeals, backed by legal briefs from groups like the Electronic Privacy Information Center (EPIC).
The company behind most of this — Flock Safety — is based in Atlanta and leases its devices to municipalities and private buyers rather than selling them outright, meaning cities never actually own the hardware.
That's the landscape Mableton residents are living inside: powerful, fast-growing, occasionally life-saving, and demonstrably fallible technology, expanding through a jurisdiction that — as we’ll explore next week in Part 2 — nobody in Mableton's own city government can yet say they're tracking.
