License plate recognition, or LPR, is cameras and software that read vehicle plates automatically and compare them with a list, such as the plates allowed to park. The cameras may be fixed at an entrance or mounted on a patrol vehicle.
What to weigh
- Hardware. Cameras, mounting and installation come on top of any software.
- Accuracy. Dirty, damaged, obscured or unusual plates are misread, so a person still has to confirm before acting.
- Privacy. Collecting and keeping plate images is regulated in some states and cities, and may require signs or limits on how long data is kept. Check local law.
In Parken Lot
Parken Lot does not include license plate recognition and does not read plates from any camera. The camera on Check a permit reads permit and visitor pass QR codes, not plates.
Enforcement is plate-based all the same: on a patrol round somebody types each plate, and it comes back as a registered vehicle, a guest on a valid pass, or not known here. See Patrol rounds.
