Once read by a ‘police’ camera, it’s likely your details will be instantly cross-referenced against multiple databases used by the cops and other law-enforcement agencies. If a vehicle is flagged as being involved in a crime, or not having the correct documentation, an action will be triggered to issue a summons/fine etc. It can also help tracked cloned vehicles, by automatically detecting impossibly quick journeys. If your car is flagged as being of interest, a variety of symbols or warnings will flash up. These will indicate the level of offence and issue a priority rating. For example, a sex offender could be flagged as high priority, while someone without tax would rate much lower.
