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.

TIn some implementations, the sensor board 1108 also includes a connector for communicatively coupling the sensor board 1108 to the image sensor array 1114. In some implementations, the image sensor array 1114 and/or the image processor of the sensor board 1108 is thermally coupled to a heat spreader 1138 that is disposed under the image sensor array 1114 and configured for dissipating heat generated while images are being captured and processed. The sensor board 1108 may include one or more of a power supply connector 11082, an AC DC converter 11084, a voltage regulator 11086 and a power unit 11088. The power supply connector 11082 is electrically coupled to the plurality of wire terminals 720, and configured to receive an external power supply. The AC DC converter 11084 is coupled to the power supply connector 11082 and configured to generate one or more DC supply voltages to drive various electronic components of the doorbell camera 106. The voltage regulator 11086 is configured to regulate the one or more DC supply voltages to one or more internal supply voltages as needed.
