Tech industry analyst Carolina Milanesi said engaging with police and offering incentives is a “very smart move by Ring” and a missed opportunity for competitors, including Google’s Nest and smaller companies such as Arlo Technologies and SimpliSafe. But a staff attorney at the American Civil Liberties Union of Southern California called the system “an unmitigated disaster” for the privacy of many neighborhoods. In one case, a doorbell camera caught footage of four burglary suspects trying to enter a residence. Three were arrested at the time, but a fourth got away. 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.
