Automatic License Plate Recognition (ALPR) - How it Works
The short version: Watermelon Parking's explainer frames ALPR as pure convenience, glossing over the fact that every car park sweep feeds a growing private database of where you go and when.
Our Take
Watermelon Parking's pitch is the same one every ALPR vendor makes: faster gate access, smoother checkout, happier customers. What the video doesn't mention is that "faster access" requires photographing and logging every plate that enters the lot, timestamped and geotagged, whether or not the driver ever opts in. That data doesn't just vanish after you pay your parking fee — it becomes another node in the sprawling network of private and public ALPR systems that can be queried, subpoenaed, or breached.
Parking garages are an easy sell for this tech because the surveillance is dressed up as a perk. But a scan is a scan. Once a company builds the infrastructure to identify cars automatically, the temptation to retain, share, or monetize that data rarely disappears on its own — and customers rarely get a real say in how long it's kept or who else sees it. Credit to Watermelon Parking for being upfront that ALPR is running in their facilities; most operators don't even say that much.
If you want to see how far this kind of plate-reading infrastructure has spread beyond parking garages — into neighborhoods, highways, and police networks — check out our camera map. And if you're ready to push back on unchecked ALPR deployment in your area, our take-action guide is a good place to start.
