Importantly, while the identity of the person performing the action may be germane to a particular advantage provided by one or more of the implementations, such identity should not be construed in the descriptions that follow as necessarily limiting the scope of the present teachings to those particular individuals having those particular identities. In some implementations, the integrated devices of the smart home environment 100 include intelligent, multi sensing, network connected devices that integrate seamlessly with each other in a smart home network e. g. , 202 FIG. 2A and/or with a central server or a cloud computing system to provide a variety of useful smart home functions. The smart home environment 100 may include one or more intelligent, multi sensing, network connected thermostats 102 hereinafter referred to as “smart thermostats 102”, one or more intelligent, network connected, multi sensing hazard detection units 104 hereinafter referred to as “smart hazard detectors 104”, one or more intelligent, multi sensing, network connected entryway interface devices 106 and 120 hereinafter referred to as “smart doorbells 106” and “smart door locks 120”, and one or more intelligent, multi sensing, network connected alarm systems 122 hereinafter referred to as “smart alarm systems 122”.

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. However, there was no evidence of CCTV having desirable effects in parking facilities or suburban subway stations. Furthermore, the review indicates that CCTV is more effective in preventing property crimes than in violent crimes. Another question in the effectiveness of CCTV for policing is around uptime of the system; in 2013 City of Philadelphia Auditor found that the $15M system was operational only 32% of the time. There is strong anecdotal evidence that CCTV aids in detection and conviction of offenders; indeed UK police forces routinely seek CCTV recordings after crimes. Moreover, CCTV has played a crucial role in tracing the movements of suspects or victims and is widely regarded by anti terrorist officers as a fundamental tool in tracking terrorist suspects.
