Plate readers in shop car parks

Yes — large retailers operate their own plate readers. In the open camera dataset, Lowe's is the single largest non-police operator in the United States with roughly 1,650 documented readers, followed by The Home Depot with about 1,050. They sit at car park entrances and exits.

Police are not the biggest operator by site count

Most coverage of plate readers focuses on police departments. But when you count the cameras whose operator is actually recorded in the open dataset, two of the three largest operators in the United States are shops.

Retailer figures merge spelling variants recorded by different volunteers ("Lowe's", "Lowes", "Lowe's Home Improvement"). Operator is recorded for only a minority of cameras, so every number here is a documented floor, not a total.

Why a hardware shop runs plate readers

The stated reason is organised retail theft. High-value, easily resold goods — power tools, copper wire, appliances — attract repeat offenders who arrive by vehicle. A reader at the car park entrance links a vehicle to a visit, and a vehicle seen at several incidents becomes a pattern.

That is a coherent security rationale. It also means a record is created for every customer who parks, not only for the small number involved in theft.

What is different about a private operator

This is the part worth understanding, because the rules are not the same.

• No public-records route. A police department is a public body subject to records law. A retailer is not. There is generally no request you can file to see what a shop's camera recorded about you.
• Policy instead of statute. Retention, access and sharing are governed by the company's own policy and its contract with the vendor, not by ALPR statutes written for police use.
• Sharing with police is possible. Private operators can grant law enforcement access to their reads, and some do. The practical result is a police-searchable record generated on private property with no public oversight of the camera's existence.
• No signage requirement in most places. You will usually not be told.

Where they sit

The pattern is consistent and easy to check once you know it. Readers go on the entrance and exit lanes of the car park, not on the building. In a store with two entrances off a main road, expect one at each. In a shopping centre, expect them on the centre's access roads rather than at each individual unit.

That placement means you are typically read on the way in and again on the way out, which establishes duration of visit as well as presence.

Checking a car park before you park

1. Open the Map tab and search the shop or centre.
2. Zoom to street level so the view cones appear. You will usually see them on the access lanes rather than in the parking area.
3. Tap a pin — where a volunteer recorded it, the operator field will name the retailer rather than a police department.
4. Use Area Stats to see the operator breakdown for the whole retail park at once.

The point is not to avoid shopping. It is that most people have no idea this category of camera exists at all, and the entrance to a DIY store is the last place they would look for one.
