The Miami Police Department is planning to use hundreds of high-tech cameras to fight crime.
Cops are moving forward with plans to attach 400 cameras to rooftops, street poles, and already-positioned red light cameras.
City Commissioner Marc Sarnoff they'll be a great tool for police and will help an understaffed police department fight crime.
The cameras will be equipped with facial recognition software and even a system called ShotSpotter that can detect gunfire and relay it back to a command center in less than 30 seconds.
The American Civil Liberties Union of Florida is voicing opposition, saying the facial recognition program is an invasion of privacy.
Sarnoff says critics' complaints are unwarranted, since there's no real expectation of privacy on a public street.
