AURORA, Colo. - Hidden atop stoplights throughout Aurora, the police department has eight cameras watching every car that passes by. They read every license plate that passes, whether you are a criminal or not.

During 2013, the cameras scanned more than 12 million license plates. Approximately 322,000 of those resulted in an alert for reasons like a stolen car or a connection to a wanted suspect.

"That plate would then be stored, not any of the registered owner's information, but just that plate and a photo of the vehicle would then be stored in our database," Mark said. "The photo of the vehicle is kept for 18 months, the actual plate number and the information relating to where the plate was scanned is kept for two years."
