New surveillance technology can track everyone in an area for several hours at a time – The Washington Post
As Americans have grown increasingly comfortable with traditional surveillance cameras, a new, far more powerful generation is being quietly deployed that can track every vehicle and person across an area the size of a small city, for several hours at a time. Although these cameras can’t read license plates or see faces, they provide such a wealth of data that police, businesses and even private individuals can use them to help identify people and track their movements. Already, the cameras have been flown above major public events such as the Ohio political rally where Sen. John McCain (R-Ariz.) named Sarah Palin as his running mate in 2008, McNutt said. They’ve been flown above Baltimore; Philadelphia; Compton, Calif.; and Dayton in demonstrations for police. They’ve also been used for traffic impact studies, for security at NASCAR races and at the request of a Mexican politician, who commissioned the flights over Ciudad Juárez.
