HOW AUTOMATIC NUMBER PLATE RECOGNITION SOFTWARE WORKS | LICENSE PLATE RECOGNITION | InterviewDOT
The short version: A technical walkthrough of ANPR software reminds us the tech behind Flock's cameras is simple pattern-matching being used for mass, permanent tracking.
Our Take
Interview DOT's breakdown of how automatic number plate recognition software actually works is worth a watch precisely because it strips away the mystique. At its core, this is optical character recognition bolted onto a camera and a database — nothing exotic, nothing that requires a warrant or a judge's sign-off. That plainness is the point: the technology is simple enough that any municipality, HOA, or private company can deploy it at scale, which is exactly what's happened with Flock Safety's cameras spreading across American streets.
What videos like this tend to gloss over is the second half of the pipeline — not just how a plate gets read, but where that read goes afterward. Flock doesn't just log your plate; it timestamps your location, links it to a vehicle history, and shares it across a growing network of agencies with little transparency or audit trail. Understanding the OCR mechanics is useful, but the real story is the surveillance architecture built on top of it: retention windows, data-sharing agreements, and the absence of meaningful oversight.
Credit to Interview DOT for pulling back the curtain on the tech itself. If you want to see how far that tech has already spread in your own neighborhood, check our camera map, and if you're ready to push back, our take-action page has concrete next steps.
