Closed Circuit Television (CCTV) is ubiquitous and we’re so used to it that we don’t even notice. These cameras are used in places like shops, restaurants and roads. They can also be found at airports, hospitals, casinos, hotels and even on the streets. In fact, wherever there are large groups of people there will be a camera.
The CCTV system can be used to monitor areas where it is not always safe, such as factories, or places that require a central control area for the best view of a particular process. This would include processes in the chemical industry as well as the interiors of reactors and facilities that produce nuclear fuel. Around 350 million surveillance cameras were installed around the globe last year. For CCTV Swindon, visit APM Fire, suppliers of CCTV Swindon systems.
Nazi Germany installed the first CCTV system in 1942 to monitor the launch of V2 missiles. The first commercial application of CCTV in the United States was in 1949. In the early days, there was no recording or storage of information. The time-consuming and expensive nature of reel-to reel recordings meant that video surveillance did not become widespread until the 1970s. The VCR was not invented until the 1970s. This technology allowed for easier recording, storing and deleting of unwanted information.
In the 1990s, technology improved so that multiple cameras could record simultaneously. Motion-only and time-lapse recordings became possible. The use of CCTV increased as a result. Internet use has been a part of recent changes.
