I've been curious about this. Are there leaked LPR databases that can be integrated with NVR's like Zoneminder, Shinobi, Blue Iris, Frigate and such? I know that some of them can read license plates but that's not entirely useful without an actual database of plates behind it. i.e. DMV, associated NCIC data, etc... As many times DMV's in many states have leaked data I would assume this must be a thing.
