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. Large scale CCTV installations have played a key part of the defenses against terrorism since the 1970s. Cameras have also been installed on public transport in the hope of deterring crime. A more open question is whether most CCTV is cost effective. While low quality domestic kits are cheap the professional installation and maintenance of high definition CCTV is expensive.

In some implementations, the device housing 702 includes a plurality of speaker openings 718 at its bottom rim surface. When the doorbell camera 106 is mounted onto a wall or doorframe surface, the speaker holes 718 are not visible from a gaze of a visitor approaching or standing near the surface, while still being able to broadcast audio messages to the visitor. In embodiments where the doorbell camera 106 includes both the microphone and the speaker, a remote user may review live video streams captured by the camera module of the doorbell camera 106, and have a conversation in real time with the visitor. In some implementations, both the microphone and the speaker of the doorbell camera 106 adopt waterproof features to deter water permeation into the electronic components within the device housing 702 and cause irreversible damages to the electronic components. Specifically, the waterproof features may be integrated at the openings 716 and 718 to deter water permeation such as from a jet or stream of water impinging on at least one of the openings 716 and 718. In an example, the microphone may be disposed inside the device housing 102, and include a sound input region offset from the microphone aperture 716. A hydrophobic membrane is affixed to a first interior surface of the device housing 702 and covers the microphone aperture 716 thereon. The hydrophobic membrane is configured to allow transmission of sound waves and block water intrusion from the microphone aperture 716. A sound transmission channel couples the sound input region of the microphone to the microphone aperture 716 on the front cover plate 708. The sound transmission channel is configured to allow sound waves transmitted through the microphone aperture 716 and the hydrophobic membrane to be coupled to the sound input region of the microphone without exposing the sound input region to damaging pressures due to environmental impacts on the doorbell camera 106. In some implementations, the speaker may also adopt a sound input region offset from the speaker openings 718 and a respective hydrophobic membrane to block water intrusion while allowing transmission of sound waves from the speaker openings 718 to the sound input region of the speaker.
