What is CCTV?
CCTV camera or TV with a closed circuit is the technology on which camcorders are connected to monitors or television screens at a predetermined location. Unlike television and digital television broadcasting, which use radio or digital transmissions to deliver images non -specific to many places, the CCTV camera has a fixed connection with monitors. Connection can be made by wiring or mixed radio transmissions that are reorganized by the receiver. This technology is often used in video supervision.
Although the CCTV in the UK is most commonly used for safety purposes, it was first used in Germany to monitor missiles during World War II. The technology, which was first designed by Walter Bruch, a German engineer known for his invention of color television, is still used to find problems in missile launch. At the end of the 1960s, the police began to grow CCTV cameras along the streets to protect businessesand public from crime. Today they are often installed in banks, shops, casinos, centers and in some private properties. They can also be used to monitor and regulate industrial processes, monitor traffic and supervise public buses, trains or metro.
CCTV The camera can be equipped with many special features such as the ability to tilt, strengthen the room or pick up pictures in the dark. The modern CCTV camera can also pick up color, get precise images of small objects over long distances, or use the Video Babies (VCA) analysis. VCA connects a camera with a computer that can then search a video for suspicious activities or specific goals; For example, a red delivery or a person who emerged near the crime place. Other features that can be used for such videos include face recognition and biometrics that are imperfectly used to identify individualsAccording to the features of the face or movements. These cameras are often controlled from the control room in another part of the building or in another building.
The extension of the use of CCTV supervision has been a controversial problem that sometimes will build security against privacy. While the CCTV camera was useful in preventing crime, accelerating the process of searching, charging and convicting criminals, and the fight against terrorism has also encountered concern for civil freedoms. CCTV critics are afraid that video supervision could be used as a form of social control, much in the way of Cointelpro, the extinct US Federal Federal Investigation Office (FBI), which used supervision as part of many, often unlawful, projects to investigate and derail dissident political organizations, civic free groups and hate groups. Others simply claim that the presence of CCTV is disturbing and adds a sense of watching, resulting in a terrible and submissive population. This phenomenon has been described in George Orwell's book 1984 in whichThe public was controlled by video by supervision and the threat of being monitored by a “big brother”, a dictator.
