State law enforcement agencies are spending millions of dollars on unmarked SUVs packed with advanced cellular surveillance equipment, according to tech commentator Silicon Cowboy, who says the vehicles can be made to look like ordinary Chevrolet Tahoes while quietly carrying hardware capable of tracking nearby smartphones.
In a recent video, Silicon Cowboy focused on public procurement records he said showed the Texas Department of Public Safety seeking nearly $4.5 million for four specially equipped 2026 Chevrolet Tahoes and surveillance systems supplied by Cognyte, an intelligence and defense company whose technology includes mobile cell-site simulators and software-defined radios.
The result, he argued, is a new generation of surveillance vehicle that can collect identifying data from phones in the surrounding area while blending into everyday traffic.
The SUVs Cost Far More Than Ordinary Police Vehicles
Silicon Cowboy said the Texas purchase included four Chevrolet Tahoes priced at about $150,000 each, far above the cost of a standard police model.
According to his breakdown, the higher price reflected modifications such as high-output alternators and secondary battery systems designed to provide continuous electrical power for sophisticated surveillance hardware hidden inside the vehicles.
He said the remaining roughly $3.9 million of the order went to Cognyte, which he described as a foreign intelligence and defense vendor that has been expanding further into the American law-enforcement market.
Silicon Cowboy also pointed to a previous Florida purchase involving nearly $800,000 in surveillance equipment designed for aircraft, arguing that the Texas order is part of a broader move toward more capable and mobile interception systems.
The most striking part of the purchase is not simply the price, but the form factor. Rather than being placed in a clearly marked command vehicle, the equipment can be concealed inside a common SUV that would not attract much attention on a public road.
How The Phone Tracking Technology Works
The central technology discussed in the video is a cell-site simulator, often referred to more generally as an IMSI catcher.
Silicon Cowboy explained that every phone has a unique identifier tied to its SIM card known as an International Mobile Subscriber Identity, or IMSI, which functions as a kind of digital fingerprint for the device.
Under normal conditions, a phone searches for the strongest legitimate cellular tower available through its carrier.
An IMSI catcher imitates that tower and attempts to convince nearby devices that it is the best available connection.
According to Silicon Cowboy, once a phone connects to the simulated tower, operators can collect identifying information and location data from the device.
He said newer systems are far more capable than the Stingray devices that became controversial years ago because modern equipment can operate across multiple generations of cellular networks rather than relying only on older 2G or 3G connections.
Silicon Cowboy Says 5G Does Not End The Problem
One of the main points in the video was that 4G and 5G protections do not necessarily prevent newer interception systems from working.
Silicon Cowboy said the Texas order included hardware and licenses associated with Cognyte’s FalcoNet system, including software-defined radio capabilities that allow the equipment to adjust dynamically across different frequencies and cellular standards.
He said the platform can run several simulated base stations at once across 2G, 3G, 4G and 5G networks.
Depending on the configuration, he claimed, the system can either imitate a legitimate 5G environment or push a phone toward a less secure connection that is easier to monitor.
Silicon Cowboy said that once a device is captured by the system, operators may be able to obtain its IMSI number, precise location and certain forms of metadata connected with calls and text messages.
That kind of capability naturally raises concerns because a system designed to locate one specific device may interact with every other phone nearby before investigators determine which one belongs to the person they are seeking.
The Equipment Can Also Fit Inside A Backpack
The surveillance tools are not limited to vehicles.
Silicon Cowboy said the procurement records also included roughly $355,000 in portable FalcoNet backpack units, which he described as battery-powered interception systems that can be carried by an officer on foot.
In practical terms, he said that means the same kind of cellular surveillance can move from an SUV into crowded places such as shopping centers, public gatherings or demonstrations.
That portability is important because it changes the scope of how the technology can be used.
A fixed surveillance vehicle is limited by where it can park or drive, while a backpack system can move directly through dense groups of people.
Silicon Cowboy argued that this is where the privacy problem becomes much harder to ignore, because the devices do not necessarily isolate one person before beginning collection.
Fourth Amendment Questions Follow The Technology
Silicon Cowboy described IMSI catchers as inherently broad surveillance tools because they interact with all compatible phones within range, not just a single device named in an investigation.
He contrasted that with a traditional search warrant for a home, where police are generally authorized to search one specific place rather than every house on the block.
With a cell-site simulator, he said, the system may collect identifiers from commuters, shoppers, delivery drivers and other bystanders simply because they happen to be nearby.
He cited federal litigation over location tracking as part of the broader legal concern and argued that the spread of these systems will continue raising Fourth Amendment questions about unreasonable searches.
He also criticized the way some purchases are approved, pointing to an emergency procurement process used in Texas.
According to Silicon Cowboy, state records showed the equipment was processed under an emergency justification even though broader budget planning for cellular tracking vehicles had already taken place months earlier.
His concern was that advanced surveillance technology can enter routine law-enforcement use faster than the public debate and oversight surrounding it.
That is a reasonable issue to raise even before courts settle every technical question, because technology tends to spread quickly once agencies have already invested heavily in it.
What Silicon Cowboy Recommends For Privacy
Silicon Cowboy ended the video by outlining several ways people can reduce what these systems may be able to collect.
He recommended disabling 2G connectivity where possible, since older cellular standards offer weaker protections and are commonly associated with downgrade attacks.
He also advised using end-to-end encrypted messaging applications rather than relying on ordinary SMS or unencrypted voice calls, arguing that intercepted network traffic is far less useful when the actual message content remains encrypted.
For situations where someone wants to prevent any wireless connection at all, he mentioned shutting the phone down completely or using a Faraday pouch designed to block radio signals.
He also encouraged people to follow public procurement records and support transparency efforts by groups such as the Electronic Frontier Foundation and the ACLU, which track police surveillance technology and related spending.
The privacy debate around these systems is unlikely to disappear, especially as the hardware becomes smaller, more mobile and easier to conceal.
If Silicon Cowboy’s reading of the procurement records is correct, the significant change is not that police suddenly discovered cellular surveillance, but that technology once associated with specialized intelligence operations is becoming easier to place inside ordinary-looking vehicles and deploy as part of routine law-enforcement work.
That shift makes public oversight increasingly important, because the most consequential surveillance tools may no longer look like surveillance tools at all.
