In the UK, the vast majority of CCTV are operated by private individuals and companies, especially to monitor the interiors of shops and businesses. The total number of local government operated CCTV was around 52,000 over the entirety of the UK, according to the Freedom of Information Act 2000 requests.
In 2002 UrbanEye published a study by Michael McCahill and Clive Norris extrapolated the number of CCTV in Greater London to be around half a million (500,000) and the total number of CCTV in the UK to be around 4,200,000. According to their study estimated there is one CCTV camera for every 14 people in the UK. For several years it has been acknowledged that the methodology behind this figure is flawed, it has been widely quoted.
In 2011 the number of private and local government operated CCTV in the UK was 1.85 million as per an article published in CCTV Image magazine .The estimate was based on extrapolating from a comprehensive survey of public and private CCTV within the Cheshire Constabulary jurisdiction. The Cheshire report claims that an average of one camera for every 32 people in the UK, whereas the density of cameras varies greatly from place to place. The report also claims that the average person on a typical day would be seen by 70 CCTV cameras.
Based on a survey and the Scottish Centre for Crime and Justice research all Scottish local authorities, identified that there are over 2,200 public space CCTV in Scotland. There were around 1.5 million private and local government CCTV estimated by The CCTV User Group including city centres, stations, airports, and major retail areas.

CCTV (closed-circuit television) transmit signals which are not publicly distributed,only a small number of people being able to access it and primarily used for surveillance and security purposes. CCTV relies on strategic placement of cameras, and observation of the camera's input on monitors somewhere. Because CCTV cameras communicate with video recorder and/or monitor across private coaxial cable runs or wireless communication links, they gain the designation "closed-circuit" to indicate that access to their content is limited by design only to those able to see it.
Walter Bruch invented the first CCTV during WW2 in Germany for observing the launch of V-2 rockets. In 1949, onwards the CCTV technology became a commercial product.
In United States, Marie Van Brittan Brown in 1962 furthers to build on Walter Bruch invention by adding a recorder to the CCTV, since the video footage from a CCTV could not be recorded. She was first to install CCTV system at their home.
In 1942 during WW2 german scientists wanted to be able to monitor V-2 rockets launch from a safe distance, hence designed the world’s first CCTV, which enabled them to monitor the rocket launch from a different location. At that time, this was a revelation as they could now, watch as if they were right next to them, but without the obvious danger.
However, this was not the modern day CCTV as there was no way to record a video. After 20 years later when Marie Van Brittan Brown in the USA utilised the technology and applied it to a security setting alongside a way of recording footage. This was the world’s first CCTV system and she and her husband installed the first one in their home. Thanks to both Walter Bruch and Marie Van Brittan Brown that many of our homes and businesses are protected against burglars by their invention.
