The system uses planes with high-resolution cameras that record a 25-square mile patch of ground for up to six hours at a time.
The product works, too.
Last year, officers in Compton, California were able to track a thief as he approached a woman, robbed her and then ran to a getaway car. The getaway car left the frame that the police were viewing, but they were able to see what type of car it was.
The technology has also been tested in Baltimore and Dayton, but not all the reviews have been great. One of the biggest critiques of the product is the invasion of privacy.
This type of surveillance tracks everything that moves in a city, but according to police, it's not as invasive since it cannot see faces or into homes.
The Center for Investigative Reporting says it provides "more security with less loss of privacy."
