In an attempt to capitalize on the ubiquity of security cameras, police are trying to search thousands of videos for suspected criminals. They input specific criteria — the name of a weapon or a region — and the computer determines if any of the images are a match.

But there is too much video to sort through. With new equipment, police in Cincinnati and in a handful of other cities will be able to archive and find videos based on certain specifications, as in: all female bank robbers using shotguns; convenience store hold-ups where the suspect wears a blue baseball cap; and other cross-referenced criteria.

Ann Thompson reports from member station WVXU in Cincinnati.
