Closed-circuit television Wikipedia

In the United States, the Constitution does not explicitly include the right to privacy although the Supreme Court has said several of the amendments to the Constitution implicitly grant this right. Access to video surveillance recordings may require a judge's writ, which is readily available. However, there is little legislation and regulation specific to video surveillance. The London congestion charge is enforced by cameras positioned at the boundaries of and inside the congestion charge zone, which automatically read the number plates of vehicles that enter the zone. If the driver does not pay the charge then a fine will be imposed.

A study of high school students in Israeli schools shows that students' views on CCTV used in school are based on how they think of their teachers, school, and authorities. It also stated that most students do not want CCTV installed inside a classroom. In Mecca, CCTV cameras are used for monitoring the flow of crowds. In 2013 Oaxaca hired deaf police officers to lip read conversations to uncover criminal conspiracies.

These devices are responsible for the recording, storage, video stream processing and alarm management. Many homeowners choose to install CCTV systems either inside or outside their own homes, sometimes both. CCTV cameras are an effective deterrent to potential intruders as their use increases the risk of identification through the camera footage. 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.

Furthermore, the review indicates that CCTV is more effective in preventing property crimes than in violent crimes. Closed-circuit television , also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point-to-point , point-to-multipoint , or mesh wired or wireless links.

CCTV surveillance is also very common in the American workplace. Many consumers are turning to wireless security cameras for home surveillance. Wireless cameras do not require a video cable for video/audio transmission, simply a cable for power. Wireless cameras are also easy and inexpensive to install but lack the reliability of hard-wired cameras.

Advanced VCA applications can accurately classify object types based on their shape and motion behavior and they can also measure object speed. Some video analytics applications can be used to virtually apply rules to designated areas. For example, they can describe which objects can enter into a specific area, when they are allowed to enter or within what circumstances. Virtually applied rules can also relate to various motion situations.

In this town, roughly 70% of buildings are single detached homes, while the remainder are mainly mobile homes. The proportions of renters and homeowners are about even. This town is primarily composed of three bedroom and two bedroom homes. Walking is not very practical for property owners in Yucca Valley as most daily needs are very inconvenient to carry out on foot. School service boundaries are intended to be used as reference only.

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.

Even though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that require additional security or ongoing monitoring (Videotelephony is seldom called "CCTV"). Due to the widespread implementation of surveillance cameras, glasses are being built which can defeat CCTV cameras. In December 2016 a form of anti-CCTV and facial recognition sunglasses called 'reflectacles' were invented by a custom-spectacle-craftsman based in Chicago named Scott Urban. They reflect infrared and, optionally, visible light which makes the user's face a white blur to cameras.

Similar systems are being developed as a means of locating cars reported stolen. 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.

Industrial video surveillance systems use network video recorders to support IP cameras.

Nevertheless, during the 1980s video surveillance began to spread across the country specifically targeting public areas. It was seen as a cheaper way to deter crime compared to increasing the size of the police departments. Some businesses as well, especially those that were prone to theft, began to use video surveillance. From the mid-1990s on, police departments across the country installed an increasing number of cameras in various public spaces including housing projects, schools and public parks departments.

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. The earliest video surveillance systems involved constant monitoring because there was no way to record and store information. The development of reel-to-reel media enabled the recording of surveillance footage.
