If you thought Flock cameras were concerning, meet what comes next.
A company called Leonardo has developed a system called ELSAG SignalTrace. It broke into public awareness just days ago and is already being marketed to law enforcement agencies across the country. It makes Flock Safety look modest by comparison.
Here is what SignalTrace does:
It clips sensors directly onto existing license plate reader cameras — the same poles, the same hardware already installed in your community. No new infrastructure required. A software and sensor upgrade is all it takes.
Every time you drive past one of these upgraded cameras, the sensor sweeps up the unique electronic identifiers of every device in your vehicle. Your cell phone. Your smartwatch. Your wireless headphones. Your fitness tracker. Your laptop. Your tablet. Your car's own infotainment system. Your tire pressure sensors. Your vehicle's Bluetooth hotspot.
And your pet's microchip.
Every one of those devices emits a signal. SignalTrace captures those signals, timestamps them, ties them to your license plate, and stores them in a searchable database for future investigative use. The result is what Leonardo calls an electronic fingerprint — a unique profile built not from your face or your name, but from the constellation of devices you carry with you every day.
Leonardo announced the ELSAG EOC Plus patent as early as May 2024, describing it as an electronic detection system for identifying people of interest through electronic device signatures. SignalTrace is the commercial product built on that foundation. The patent came first. The marketing came after. The sales calls are happening now.
Here is where it gets worse.
SignalTrace is explicitly designed to track vehicles even when the license plate cannot be read. If your plate is obscured, dirty, or misread — it does not matter. The system identifies your vehicle by the electronic fingerprint of the devices inside it instead. The plate reader becomes optional. The surveillance does not.
The strategic advantage for police agencies is adoption friction. SignalTrace can be pitched as an extension of an existing ALPR ecosystem rather than a wholly separate surveillance buildout. That is exactly what happened with Flock. License plate readers went in first. Video came later through a software update. Nobody voted on the expansion. Nobody was told. SignalTrace follows the same playbook — attach to existing infrastructure and expand what it captures without requiring a new procurement process, a new vote, or a new public conversation.
Who is Leonardo and why does their background matter?
Leonardo US Cyber and Security Solutions is not a Silicon Valley startup. It is the American subsidiary of Leonardo S.p.A. — one of the largest aerospace, defense, and security conglomerates in the world, headquartered in Rome, Italy. Recent public market estimates place Leonardo S.p.A.'s market capitalization at approximately €29.76 billion — roughly $32 billion USD. For context that is nearly four times Flock Safety's valuation.
Leonardo's US operations trace back to a joint venture with Remington Arms in 2004, became a wholly owned subsidiary in 2008, and in 2024 rebranded from Selex ES Inc. to Leonardo US Cyber and Security Solutions — a change the company said better reflects the synergy between its brand and the cutting-edge products it offers. Leonardo US has manufacturing facilities in Greensboro, North Carolina and software engineering in Brewster, New York. Its US arm holds contracts with US Special Operations Command and the General Services Administration. This is a major international defense contractor with a direct pipeline from special operations military applications to local American law enforcement.
The Italian government holds a significant ownership stake in Leonardo S.p.A. That means a foreign government — through a defense contractor — is selling surveillance technology to American law enforcement. If the Flock Safety story involves a CIA-seeded venture capital network, the Leonardo story involves a partially state-owned Italian defense conglomerate with US Special Operations Command contracts. Neither of these companies is what most Americans picture when their city council votes to upgrade the cameras on a street pole.
What is ELSAG — and why SignalTrace is more dangerous than it sounds.
ELSAG is Leonardo's license plate recognition product line — the company's core law enforcement technology that has been deployed across American communities for over two decades. ELSAG cameras are what you think of when you picture a standard license plate reader. Fixed cameras on poles. Mobile units mounted on patrol vehicles. Solar powered. Cellular connected. Reading plates and logging vehicle data.
ELSAG is already deployed in all fifty states. Virginia State Police is a documented customer. Leonardo holds statewide procurement contracts in New York, Maryland, New Mexico, Ohio, and Pennsylvania among others, and is listed on the federal GSA schedule available to agencies nationwide. Their cameras are already on street poles and patrol vehicles across the country — quietly, routinely, and largely without public awareness.
SignalTrace is not a new camera. It is not a new company. It is an upgrade — a sensor that clips directly onto ELSAG cameras already in the field and adds a new layer of data collection on top of the license plate reading that was already happening. The same pole. The same hardware. A new sensor attached to it that now also sweeps up every electronic device signal in every passing vehicle.
That is precisely what makes it so significant. The deployment barrier is almost zero. Any law enforcement agency that already has Leonardo ELSAG cameras can add SignalTrace capability without purchasing new infrastructure, without a new procurement process, and — depending on how their existing contract is written — potentially without returning to their city council for approval. Sound familiar? It should. It is the exact same function creep mechanism that allowed Flock Safety to add video streaming, vehicle fingerprinting, and AI people search to cameras that were originally sold as simple plate readers.
The infrastructure goes in first. The capabilities expand later. The public finds out last — if at all.
Leonardo's defense of the system sounds very familiar.
They say SignalTrace captures device signals but does not read the contents of communications. They say it stores data until a specific investigative request is made of the system by an investigator. They say it was designed to ensure it does not infringe on the rights of individuals.
That is the exact same argument Flock Safety makes about license plate readers. It captures plate numbers but not driver information. It stores data until law enforcement queries it. It was designed with privacy in mind.
Courts are still debating whether Flock's version of that argument is constitutionally sound after eight years of deployment and 80 plus cities canceling contracts. SignalTrace captures exponentially more data about exponentially more people — not just the vehicle but every person inside it and every device they carry. If the argument barely holds for plate readers, it almost certainly does not hold for a system that vacuums up every electronic signal emitted by every device in every vehicle passing a sensor.
The data retention problem.
With Flock we at least know the default data retention period is 30 days — though the contract language grants Flock a perpetual license to use that data regardless. With SignalTrace the situation is more opaque. Leonardo's product materials state that all data collected may be uploaded to the EOC server and archived for future queries and analysis — with no published retention limit. How long does Leonardo store your electronic fingerprint? Who has access to it? Can it be shared with other agencies or federal entities? Can it be purchased by data brokers? Leonardo's materials do not answer these questions. That silence is itself an answer.
The retail and private deployment problem.
Leonardo is actively marketing SignalTrace to shopping malls, retail centers, and private businesses — not just law enforcement. Their materials describe deploying SignalTrace in parking lots and inside shopping centers to track individuals involved in organized retail crime. By identifying and correlating electronic devices carried by suspects, retailers can gain critical insights into criminal patterns.
That means SignalTrace sensors could be on private property you visit every day — your grocery store parking lot, your shopping mall, your workplace — operated by a private company with no law enforcement oversight, no warrant requirement, no public accountability, and no notification to you. Your electronic fingerprint captured every time you park your car. Stored indefinitely. Shared with whoever the private operator decides to share it with.
The no-plate-needed problem — and what it means for pedestrians.
The implication of being able to track a vehicle by its electronic fingerprint without reading the plate goes further than most people realize. Deliberately obscuring your plate — which some people do to avoid surveillance — provides zero protection against SignalTrace. The sensor does not need the plate. It reads your phone.
More critically — the sensor does not know or care whether the device it is reading is inside a vehicle or in the pocket of a pedestrian walking past the pole. A person walking down the sidewalk past a SignalTrace-equipped camera is emitting the same Bluetooth and Wi-Fi signals as a person driving past in a car. The system's sensors capture signals from whatever passes within range. Whether that includes pedestrian device capture is not addressed in Leonardo's public materials. The fact that it is not addressed is worth noting.
Does Flock plan to integrate or copy this technology?
No confirmed partnership between Flock and Leonardo has been announced. But four things are worth noting.
Flock already expanded into audio detection in October 2025 — their Raven devices now listen for human distress and alert officers when they detect screaming. Device signal detection is the next logical step in exactly the same direction. Flock's product roadmap has consistently expanded from vehicle data toward person data. Vehicle fingerprinting. FreeForm people search by physical description. Audio detection of human behavior. Electronic device fingerprinting would complete that progression.
Flock's Wing platform is specifically designed to pull third-party camera infrastructure into its ecosystem. If Leonardo's SignalTrace cameras are deployed in a city that also uses Flock, the data from both systems could flow into the same FlockOS platform without any formal partnership between the two companies.
Flock's Nova platform already combines license plate data with court records, jail records, CAD records, and commercially available personal data. Adding device signal intelligence to that profile would be consistent with what Nova is already designed to do.
And Flock's entire business model is built on continuous software-defined capability expansion through over-the-air updates. No new hardware. No public vote. Whether Flock is currently developing device signal detection capability is something we do not know. Whether the competitive pressure from Leonardo creates a powerful financial incentive for them to do so is not in question.
The constitutional problem is worse than anything we have discussed before.
The Fourth Amendment arguments against Flock center on the aggregation of license plate reads into a comprehensive record of your vehicle's movements. Courts are divided on whether that crosses the constitutional line.
SignalTrace does not aggregate your vehicle's movements. It aggregates your personal electronic identity — every device you carry, every signal you emit — and ties it permanently to a location, a timestamp, and a plate number. It does not track your car. It tracks you. Personally. Individually. Every time you pass a sensor, whether you are suspected of anything or not.
The legal issue is that public policy often treats each input separately — a plate image, a device signal, a timestamp, a location record. SignalTrace's purpose is to combine recurring signals into a searchable investigative profile. The Mosaic Theory argument we have made against Flock says that aggregated location data eventually reveals the whole of a person's life. SignalTrace is designed from the ground up to reveal exactly that — not as a byproduct but as the product.
The Supreme Court has not ruled on whether device signal collection at this scale requires a warrant. The courts have not yet caught up to Flock. They are further still from catching up to what Leonardo is now selling to law enforcement agencies in all fifty states.
Why this matters right now.
We are currently waiting on the City of Texarkana to respond to our public records requests about Flock Safety cameras already operating on our streets. We do not yet know how many cameras exist here, which features are active, or what data sharing agreements are in place.
What we do know is that the surveillance infrastructure being built across America — of which Flock Safety is the most visible example — is expanding faster than public awareness, faster than legislation, and faster than the courts can rule on it.
The cameras in our area are one node. SignalTrace shows you what the next node looks like. And the one after that. Each addition is sold as a modest upgrade to existing infrastructure. Each addition captures something your government previously could not capture without a warrant. Each addition happens without a public vote.

Today, on my final day as Director of National Intelligence, I’m releasing never-before-seen communications and documents exposing how Dr. Fauci provided millions in US taxpayer dollars to fund dangerous gain-of-function research at the Wuhan lab, worked with politicized elements within the Intelligence Community to suppress the truth about his actions and hide the virus’ lab-leak origins, and lied to Congress while under oath in 2024. It’s time you know the truth.

Unclassified 2021 DARPA briefing document to the Department of Defense:
"1. SARS-CoV-2 is an American-created recombinant bat vaccine, or its precursor virus. It was created by an EcoHealth Alliance program at the Wuhan Institute of Virology (WIV), as suggested by the reporting surrounding the lab leak hypothesis." ⬇️
I am proud to be teaming up with Karen Bass' brother in suing his sister for her reckless negligence that led to the destruction of our homes. I hope their Thanksgiving dinner isn't too awks. I know ours hasn't been the same since last year...
Today, I’m releasing never before seen intelligence revealing new evidence of past US government funding for more than 120 biolabs in over 30 countries, including Ukraine.
In support of President Trump‘s Executive Order to end federal funding of dangerous gain of function research around the world, and increase transparency and accountability, ODNI will continue working with partners across the Administration to identify where these labs are, what pathogens they contain, and what “research” is being conducted.

Donald Trump ran for President claiming he would be the one to drain the swamp.
Instead, he built a fortress around it, protected it, and fully became king of the swamp.
Lindsey Graham has an F rating for his conservative voting score card and loves war almost as much as Mark Levin.
This is repulsive.
Thank you Thomas Massie for recognizing the heroic members of the USS Liberty, which was attacked by Israel, where 34 crew members were killed and 174 were wounded.
Why did our “greatest ally” attack us??
🚨NOW: Rep. Thomas Massie just stood on the House floor and named what every politician in DC has spent 58 years pretending did not happen
The USS Liberty. June 8, 1967.
34 dead American sailors. 174 wounded. Over 70% casualty rate on a virtually unarmed US ship.
25 minutes of Israeli jets, Israeli rockets, Israeli 30mm cannon fire, and ISRAELI NAPALM ON THE BRIDGE. Then Israeli torpedoes. Then Israel machine-gunned the lifeboats.
MASSIE: "They were intent on leaving no survivor."
Then the part nobody wants you to think about: the Saratoga and the America launched planes to help. The planes were RECALLED. The crew sat there bleeding for 17 hours.
Dean Rusk. Richard Helms. Admiral Moaner. The chief counsel of the Court of Inquiry himself. None of them believed the "mistaken identity" story.
And now you understand exactly why the entire DC machine and Israel lobby has spent the last year trying to primary this man out of existence.
You are not allowed to say the quiet part. He said it anyway.
Honor the crew. https://t.co/XuDLeFF4gJ.
Constitution requires two-thirds vote from the Senate to bind us to another country.
They hid it in the bill because they knew it was unconstitutional.
It’s treasonous as far as I’m concerned.
Every single person who voted for this needs removed from office.
Thomas Massie says the conspiracy theorists were right again about Section 224 of the NDAA, which he says will merge the United States military with the IDF.
Massie says the provision is treasonous and warns that it will force the United States to compromise its own security for Benjamin Netanyahu's demands.
"The difference between a conspiracy theory in Washington has been reduced from six months to six days."
They spy on you without a warrant, then hide behind a secret court. That's not how the Constitution works.
My Fourth Amendment Restoration and Protection Act stops warrantless surveillance of Americans.
We are nearly $40 trillion in debt. Working families are stretched thin. And Washington is still sending federal benefits to people who entered this country illegally.
My End Welfare for Non-Citizens Act supports American citizens instead of rewarding those who came to the U.S. illegally. This is basic fiscal responsibility, and it is long overdue.
We just said goodbye to our good friends Thomas and Carolyn Massie.
The civil war in the Republican Party is successfully gutting the true America Firsters, like myself, Thomas and others.
But I don’t think most Americans realize the extent of what’s happening, how bad it is, and what it’s going to produce.
After taking the hard principled stand against war with Iran in June 2025 and releasing the Epstein files, the neocon controlled Republican establishment now backed by the President set out to destroy us.
Thomas and I took two different routes but ended up in the same place, which delivered a message to our colleagues to never go against the President even on issues he himself promised to do and at the same time delivered the louder stronger message to the American people that no matter what they say on tv, rally stages, committee hearings, campaign ads, or stump speeches, Republicans and Trump have overwhelmingly rejected America First and will do anything possible to cut the head off of anyone who tries to fly its banner.
The extent and extremes to which they have gone should shock everyone.
For me, I was Trump’s loudest champion for years supporting him when no one else would, voting with him 98% of the time, and he called me a traitor for releasing the Epstein files, refusing to support war with Iran, and fighting against the White House’s bad policies that only serve their donors like a 10 year moratorium on state rights to regulate and make laws on AI and data centers.
And yet my perfect conservative voting record, legislative accomplishments like the House passing my articles of impeachment of Biden’s DHS Secretary that oversaw the invasion of our country, passing my bill making it a felony to trans children under 18, my work as DOGE Chair defunding waste fraud and abuse and so much more, suddenly meant nothing to low educated Republicans that are easily manipulated by bot armies and bought and paid for social media influencers that spread absurd lies about me.
After supporting the Republican Party by paying all of my dues to the NRCC every Congress, endorsing and campaigning for Republican candidates, and spending millions and traveling the country to get Trump elected, to be called a traitor and not a single Republican (even the ones I helped get elected like JD Vance and others) not to utter a word of public support for me, it became abundantly clear that the Republican Party is something I can no longer support and want nothing to do with.
None of my policy views have changed, but everything changed about the man I supported to be president and the party I supported to gain the majority.
They are all under full capture and control.
And if you refuse to be captured and controlled with them, then their captors will set out to kill you, and the party sits in silence while it happens.
What they just did to Thomas Massie is unforgivable. I saw it all coming early, had just watched my friend Charlie Kirk assassinated, and knew they were going to do all of it and probably worse to me too, so I refused to allow it to happen to me, my family, and my district, so I resigned.
But Thomas stayed in the fight and they slaughtered him with tens of millions of foreign donor dollars that fueled lies, slander, character assassination, and even broke their own laws to do it.
They told lies to Kentucky’s 4th district that Massie had turned into a liberal Democrat, voting for Democrat policies, and even made vicious lying illegal AI ads showing him in a sexual relationship with AOC and Ilhan Omar.
Even though ALL of it was horrific lies proven wrong with his own 14 year impeccable America First liberty driven voting record, naive older voters in his district were easily fooled by the AIPAC and Israel funded campaign lies, and voted for a new candidate who refused every single debate with Thomas Massie and has no voting record to prove what he stands for at all.
The capture is complete.
What will you do about it?
