CCTV is the acronym for closed circuit television. CCTV systems are surveillance systems most commonly used to enhance security. Video cameras, with various sophisticated capabilities, are used to send signals to designated monitors, where images can be monitored live and stored for future viewing.
The first CCTV system was implemented in the 1940s by a renown German engineer, Walter Bruch. Bruch used this new technology to observe the launching of V-2 rockets, as an aid to detecting and troubleshooting any malfunctions. Then in 1960s, the CCTV systems were introduced in the US in the city streets of Olean, New York, to discourage crime. The use of the video cameras made the city of Olean a pioneer in US of this crime-fighting technology.
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 are very useful in law enforcement to maintain social control, recognize and monitor threats, and prevent and investigate criminal activity. Law enforcement personnel credit CCTV systems as a cost-efficient way to improve security. Because the clarity of recorded images is often excellent, the video footage can provide valuable evidence for crime solving.
With the rise of violence in schools, incidents of public shootings, and the ongoing threat of future terrorist attacks, the use of CCTV systems by all levels of government is significant. Surveillance cameras are used to heighten security in government buildings, airports, military installations, subway stations, hospitals, schools, and numerous other public facilities for enhanced security and public safety.
The personal use of CCTV technology has become more widespread as the technology has become more affordable and easier to use. Many homeowners utilize CCTV systems in their own homes for added security and protection for their families. Special cameras referred to as "Nannycams" are sometimes used in homes to monitor child care provided by babysitters or nannies.
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.
