Surveillance Technology as Evidence in Florida Criminal Cases: What You Need to Know
When I started defending criminal cases in 1993, the star witness was a person. I cross-examined that person. I watched how they handled pressure, looked for inconsistencies between what they told police and what they said on the stand, and found ways to show the jury why their testimony deserved scrutiny. Cross-examination gets you to the truth. It’s one of the most powerful tools the adversarial legal system has.
That model is changing. Prosecutors don’t always bring a person to the stand anymore. They bring data. Surveillance footage, automatic license plate reader logs, cell tower location records, private camera networks. The technology becomes the star witness, and cross-examining technology is a fundamentally different challenge.
Charged Based on Technology Evidence in Florida?

What’s Actually Tracking You in Florida Right Now
Automatic License Plate Readers (ALPRs) are already standard equipment across Central Florida. These systems sit on police cruisers and fixed poles on busy streets, scanning every license plate that passes and logging the time and location. Officers who once needed to run a plate manually now get real-time alerts when a vehicle of interest enters range. The system knows where you were, what time you were there, and what car you drove. It doesn’t require a warrant to collect that data. It just collects it.
Cell tower data works on similar principles. Every time a cell phone connects to a tower, the carrier logs the connection. Location data builds up passively — without any active tracking decision — and becomes a record of where a phone traveled over days, weeks, or months. In Carpenter v. United States, 585 U.S. 296 (2018), the U.S. Supreme Court held that accessing historical cell-site location information from a carrier requires a warrant. However, the data still exists, and the warrant requirement doesn’t always stop law enforcement from trying to use it.
Private camera networks add another layer. Ring doorbells, business surveillance systems, and residential cameras often record continuously on 30-day loops. When something bad happens in a neighborhood, law enforcement contacts private property owners — or their contractors — for footage. That footage can place a car or person at a location without any government-controlled surveillance system being involved at all.
The Private Company Problem
Here’s the part of this equation I find most concerning from a defense standpoint. When a government agency collects data on citizens, constitutional rules apply. Those rules require transparency, regulate how long data can be stored, and limit who can access it. When a private company operates the surveillance system, those rules often don’t apply the same way.
ALPR systems in many Florida cities operate under contracts with private vendors. The vendor collects the data, stores it, and sets the retention policies. How long does your license plate location history sit in a private database? Who can query it? Can it be sold, shared, or accessed by other agencies without your knowledge? These are questions the public rarely asks because the contracts get signed at the city council level, framed as public safety initiatives, without most residents knowing what they’ve agreed to. The pitch is always safety. The question nobody asks is: safety for whom, and at what cost?
Why This Creates Real Defense Challenges
Technology evidence creates a specific problem in a courtroom: it arrives with an implied authority that human witnesses don’t have. A jury looks at a license plate reader log and sees numbers, timestamps, and coordinates. It looks objective. It looks infallible. The bias that might affect a human witness’s memory or testimony doesn’t seem to apply.
But data can be wrong. Systems malfunction. Databases have errors. The chain of custody for digital evidence can break just as easily as the chain of custody for a physical object. Furthermore, the constitutional question of whether the data collection itself was lawful doesn’t disappear because the evidence looks clean on a spreadsheet. Evidence collected in violation of the Fourth Amendment can still be suppressed, regardless of how neatly it prints.
The legal framework for challenging technology evidence continues to develop. Carpenter addressed cell tower data but left many adjacent questions unanswered. ALPR data, private surveillance footage, and facial recognition results each carry their own constitutional questions that courts still work through. A defense attorney who understands this landscape can ask the right questions about how data was collected, how long it was stored, who had access to it, and whether the use of it in a specific case required a warrant that law enforcement may or may not have obtained.
What You Should Ask About at the Local Level
The surveillance infrastructure that ends up as evidence in criminal cases starts with contracts signed by local governments. Before a city approves a new ALPR network or a private camera partnership, questions should be on the table: Who approved this technology? What data does it collect? How long does it store the data? Who can access it? Can the data be shared with other agencies or private companies? What oversight exists for how investigators use it?
These aren’t abstract civil liberties questions. They’re practical questions about what ends up in a prosecutor’s evidence file years after a city council signs a contract without public discussion.

John’s Takeaways
- Surveillance technology is now a primary evidence source in Florida criminal cases. ALPR data, cell tower logs, and private camera footage are showing up in cases large and small.
- Private companies operating surveillance systems don’t face the same transparency and oversight rules as government agencies. The data they collect on your movements may have far weaker legal protections than most people assume.
- In Carpenter v. United States, 585 U.S. 296 (2018), the Supreme Court required a warrant for historical cell-site location data. The rules for other surveillance data are still developing, and courts are working through them case by case.
- Technology evidence can be wrong, misinterpreted, or unlawfully collected. None of those facts prevent prosecutors from presenting it, but a well-prepared defense attorney can challenge all of them.
- The surveillance infrastructure in your community starts with local government contracts. The questions about data retention, access, and oversight deserve to be asked before those contracts get signed, not after.
Charged Based on Technology Evidence? Let’s Look at How It Was Obtained.
I’ve been following digital and surveillance evidence in criminal cases since it started showing up in my files, and the constitutional questions it raises are exactly where a well-prepared defense attorney goes to work. I represent clients across Orange, Seminole, Osceola, Lake, Brevard, and Volusia County.
Give my office a call. Let’s look at what the technology actually shows, how it was obtained, and whether it belongs in your case.
