Maryland's New Police-Car-Mounted Cameras Read License Plates

Patrol Car Mounted Cameras Can Read License Plates
Johnny Law's technological arsenal continues to grow by leaps and bounds. Over the past year or so, we''ve seen criminals fitted with GPS trackers, police soliciting help via text message and YouTube, a drivers license scanning PDA, and even a multi-lingual gadget that can translate spoken commands. That's why it comes as no surprise when the police show off yet another fancy tech-toy that is helping them nab crooks.

As the Washington Post reportes, the latest weapon in the war on crime is a pair of cameras mounted on the top of police-car rooftops. Said cameras snap photos of license plates on cars in front of and behind the police cruiser. The photos are then decoded using advanced image processing techniques, which read the numbers from the license plate and feed them through a police database looking for matches. Originally, these systems were purchased by Maryland police to help reduce car theft, but seem to have found just as happy a home pulling up unpaid traffic tickets.

Of course, don't expect privacy advocates to go quietly into the night on this one. The indiscriminate running of plates (police estimate the computer can check the records of 3,000 vehicles a day) strikes many as overstepping acceptable bounds. The British may be used to this level of surveillance, but Americans tend to be a little more uneasy about "the man" watching their every move. [Source: Washington Post]
