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.

The CCTV systems have become a welcome partner to law enforcement. Along with its main purpose of combating crime, CCTV systems have become an invaluable tool in keeping public order. Speed cameras have been installed to monitor traffic violations, congestion, littering, loitering, and other civil violations.

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.

CCTV systems have gained great public acceptance. There may be some critics, with privacy issues, but the general public agrees that this tool deters crime and makes them feel safer. CCTV systems have become a symbol of security and safety in our modern society.
