The Amazon-owned security doorbell company Ring has entered into partnerships with over 600 police forces across the U.S. that allow the law enforcement agencies to request video recorded by any Ring camera, reported The Washington Post. As long as officers provide the case number for a specific crime, they can request Ring footage captured within a half-mile of the crime scene, over a 45-day span. Ring customers are given the option to decline the request, and police can collect no more than 12 hours of video surveillance from any one home. Once they download the footage, there are few restrictions on how of for how long law enforcement may use the footage, the company stated in a letter to Democratic Sen. Ed Markey of Massachusetts.
