Police departments from Bakersfield, Calif., to Scranton, Pa., and beyond are piloting and deploying body-worn cameras (BWC) in increasing numbers, a movement happening just as privacy issues gain greater attention across the nation.

While many hold out hope that BWCs will bring greater accountability and transparency of police actions, the technology also has the potential to cut into citizens’ privacy.

Amazon has made its entry into the surveillance business with a facial recognition system, Rekognition. The product is geared towards law enforcement use, and has already been used in select police departments around the country.

The AI-based program can track, identify and analyze people in real-time. It is powerful enough to identify up to 100 people in a single image and scan the information quickly against databases.
