The UnicamSCAN system is dedicated to preventing crime and ensuring public safety. Thanks to automatic license plate reading, the system searches for stolen vehicles, vehicles of interest, monitors buildings near roads etc. Characters from all automatically read license plates are compared on-line to the official version of the police database of stolen vehicles. If the license plate is found in the database, an alarm is alerted. The daily database updates are automatic. The system is field proven and in a routine operation by the Czech Police.
