After the homeowner gave Arcadia detectives some Ring video clips, police identified and arrested the last suspect. Hammond, Indiana, also put up money to offer Ring cameras at a discount. Lt. Steve Kellogg said the partnership was a natural move for a city that already uses cameras to read license plates. "You cannot enter or leave our city without . being captured on film," he said, adding that doorbell cameras are the next logical step. "We thought, 'Well, the only angle we don't really have is cameras right by the homes. '"He said sharing video is voluntary. Green Bay, Wisconsin, gets one free camera for every 20 people who sign up for the Ring app through a city link. Initially, police required recipients of those free cameras to agree to provide any video police requested. It dropped the requirement after The Associated Press began reporting this story.
