My parking garage is using Flock Safety cameras to scan license plates: is this legal under the DPPA?

Real talk: so I just found out my office parking garage (managed by a national parking company) installed Flock Safety ALPR cameras at every entrance and exit. They're scanning every license plate that enters and exits the facility. I only discovered this because I noticed the cameras and Googled the model number.

There was zero notice to parkers — no signage, nothing in the parking agreement I signed when I got my monthly pass last year.

I know there was a recent ruling in California (Bartholomew v. Parking Concepts) that touched on this exact issue. Does anyone know where this stands legally? I'm particularly concerned about:

1. Where does this data go and how long is it retained?
2. Flock Safety shares data with law enforcement through their FLUX network — does that change the analysis?
3. Is there any obligation to notify parkers that their plates are being scanned?

This feels like a massive privacy issue that most people don't even know about.
