"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.

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."
