The LA County Board of Supervisors voted a couple of months ago to help residents in the county buy Ring doorbell cameras, which let you monitor your home from afar. Hundreds of police departments across the country are using Ring footage to help solve crimes. The LAPD says its partnership with Ring helped cut burglaries in half in 2015. And some smaller cities here, like Arcadia, have already partnered with Ring to pay residents to install cameras on their front doors. However, some privacy experts are worried about this technology.
