CCTV later became common in banks and stores to discourage theft, by recording evidence of criminal activity. In 1998, 3,000 CCTV systems were in use in New York City. The studies included in the meta analysis used quasi experimental evaluation designs that involve before and after measures of crime in experimental and control areas. However, several researchers have pointed to methodological problems associated with this research literature. First, researchers have argued that the British car park studies included in the meta analysis cannot accurately control for the fact that CCTV was introduced simultaneously with a range of other security related measures. Second, some have noted that, in many of the studies, there may be issues with selection bias since the introduction of CCTV was potentially endogenous to previous crime trends. In particular, the estimated effects may be biased if CCTV is introduced in response to crime trends. It has been argued that problems of selection bias and endogeneity can be addressed by stronger research designs such as randomized controlled trials and natural experiments. A 2017 review published in Journal of Scandinavian Studies in Criminology and Crime Prevention compiles seven studies that use such research designs. The studies included in the review found that CCTV reduced crime by 24 28% in public streets and urban subway stations. It also found that CCTV could decrease unruly behaviour in football stadiums and theft in supermarkets/mass merchant stores.

But Ring doesn’t always remind customers of that fact. In one request from May, sent by police in Bloomfield, Ring starts by informing people that “Sharing videos is absolutely your choice. ” In another message sent by El Monte police in June, that explicit disclosure wasn’t present. Instead, the email says, “If you would like to take direct action against crime in your community, this is a great opportunity. ”As internet connected camera technology has gotten cheaper and easier to use, Ring became just one of a number of consumer surveillance companies to partner with police. Flock, which makes license plate readers targeted toward groups like homeowners associations, has similarly touted its relationship with law enforcement, for example. Many of the details of how these corporations assist police remain secret. Ring wouldn’t disclose exactly how many police departments it is working with. “We should definitely be concerned about this surveillance network that is being built, this public safety infrastructure that is being built, that isn’t going through a full proper process,” Maass says. The Ring Doorbell makes it easy to know who is at your door at any given time. And if you don't have your mobile device nearby to check for alerts, you can easily ask Alexa to let you know.
