Smoke Detector

2. 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. Gill and Spriggs did a Cost effectiveness analysis CEA of CCTV in crime prevention that showed little monetary saving with the installation of CCTV as most of the crimes prevented resulted in little monetary loss.For example, you can create rules to have the lights turn on when motion is detected, have your doors unlock when a smoke alarm goes off, and have a camera begin recording when a sensor is triggered.Some systems store recorded video locally on an SD card or a solid state drive, while others offer cloud storage.Locally stored video is a good choice for do it yourselfers on a budget, but you have to be careful not to *overwrite video you may need later.Cloud *storage makes it easy to store and access recorded video, but *it can cost hundreds of dollars per year depending on your subscription.Some *systems offer both cloud storage and local storage, *and some provide a dedicated storage drive that gives you DVR capabilities with time lapse recording, which makes it easy to find a video event that took place at a specific point in time.

Critics however noted that benefits of non monetary value cannot be captured in a traditional Cost Effectiveness Analysis and were omitted from their study. A 2008 Report by UK Police Chiefs concluded that only 3% of crimes were solved by CCTV.

Daytime 1080p video from this camera was excellent, but nighttime video was less defined; it was hard to make out people's faces. The camera is weather resistant, but the connection between its cable and power supply is not.
