In 1960, UK officials began installing CCTV Camera systems in public places to monitor crowds during demonstrations and public figures. Camera mounting is becoming more popular, both in public spaces and retail stores, as the technology is being developed. Today in Britain, Camera CCTV monitors roads, sidewalks and pitches in the city center, railway and public bus stations, as well as in retail stores and other businesses.

In the United States, the first CCTV Camera system was set up in a public building in 1969 in the New York City building. This practice quickly spread to other cities and was soon widely implemented. Unlike the UK, CCTV cameras in public spaces in the United States are rarely used.

Differences CCTV camera with other digital cameras

Basically CCTV cameras are not different from other digital cameras because the basic function of the camera is to capture images of certain objects and display them into video or image formats in certain formats. The fundamental difference between CCTV cameras with other digital cameras is If in digital cameras known term megapixel to determine the quality of the resulting image, then in the CCTV cameras known as TVL (TV Lines). Megapixel is a unit used to measure how many points are generated to create an image while TVL is the unit used to measure how many horizontal and vertical lines are generated to create an image. However, there are types of CCTV cameras that use the megapixel camera type CCTV IP.

In addition to resolution, another fundamental difference is the designation of the camera itself, digital cameras generally serve to take a picture of a particular object at a certain time while the CCTV camera serves as a surveillance camera that will certainly work all the time to supervise a particular object. Here it is clear that CCTV cameras have the ability to operate standby for 7 x 24 hours for a week without rest which this capability is not owned by other digital cameras.
