Closed circuit television (CCTV) is a television transmission system, which can be wired or wireless. It sends signals by cable (wired) to a monitor or directly to the monitor by radio waves (wireless). CCTV systems most often refer to security and surveillance camera systems.

The first CCTV systems were utilized in the 1940s by the military. Walter Bruch, a renowned German engineer, created the first design and installation. The CCTV system was used during the testing of V-2 missiles in order to safely monitor the tests. Later in the early 1960s, the United Kingdom began installing CCTV systems in public places to monitor crowds during rallies and appearances of prominent public figures.

Today CCTV systems are being used extensively to fight crime and to protect the public. As a result, its capabilities are constantly being improved to include more sophisticated technologies. A modern system can include cameras equipped with pan, tilt and zoom capabilities, as well as night vision, computer assisted operations, motion detection, and even face recognition. Plus, the camera casings are usually bullet-proof and have automated defense mechanisms to protect them from possible damage by intruders.

Today in the US, it is common for business establishments prone to security threats to use CCTV systems. Banks, convenience stores, large retail stores, for example, install surveillance cameras to discourage theft. With the large number of ATM’s across the nation, banks have gone a step farther and installed surveillance cameras at the ATMs as an additional defense against theft.

CCTV systems play a major role in the field of law enforcement and continue to “take a bite out of crime”. In addition to preventing, detecting, and even solving some crimes, CCTV cameras have been extended to assist law enforcement in civil matters as well. Speed cameras have been installed to monitor traffic violations, as well as traffic congestion, littering, and loitering.

CCTV systems are important to government security, particularly after the September 11, 2001 terrorist attacks on the US. CCTV systems are used globally to enhance security and prevent future terrorist attacks. It was in 1993, that surveillance cameras were installed in the World Trade Center as a preventive measure against terrorist attacks. This is a good example of the widespread usage of CCTV systems throughout the world and its role for enhanced security.

CCTV systems can be installed to provide safety features in transportation or recreational facilities. On a subway train, for example, the video cameras allow the operator to verify that the doorways are clear, before closing the doors and starting the train. Another example would be the operator of an amusement park ride. The CCTV system ensures that all riders are safely seated on the ride or safely exited the ride, before the ride is put into motion.

The majority of the general public views the use of CCTV systems positively. There are a some critics that point out the loss of privacy of persons under surveillance, as wells as the negative impact of surveillance on civil liberties. That argument is flawed. Why? — because CCTV cameras are usually for surveillance of “public” spaces, not private. Another important point is an individual’s rights to privacy can be outweighed by the need to protect the public welfare.
