Students at Detroit schools will face photo-taking detection machines that will indicate the location of any metal objects on their bodies.

Detroit Public Schools is the first district in the nation to install the machines, similar to airport security systems, it in all of its high schools, the Detroit Free Press reported Sunday.

 Students returning to classes next week will be scanned by the systems at each campus.

 The walk-through detectors use advanced magnetic technology to pinpoint threatening objects while ignoring common items such as coins, body piercings and small keys, said a UPI report. 

The Detroit schools system spent $534,000 to buy and install 60 units in its 32 high schools, the report said.

 The units create an image that appears on a monitor, indicating where metal is detected, and the photos and information can be stored for months or years.
