The Grandview (Mo.) Police Department has equipped one of its patrol cars with the Mobile Plate Hunter-900 to scan and process every license plate on a busy street, the Kansas City Star reports.
The system's three external cameras feed an on-board computer that scans every plate and runs it through police databases. If there's a match, an alarm sounds, allowing the officer to take appropriate action.
The system is produced by ELSAG North America Law Enforcement Systems.
