Closed circuit television (CCTV) refers to a surveillance technology used for monitoring various locations and activities. The CCTV systems use cameras to send signals and video footage to a designated monitor, which can be a simple black and white television, desktop computer, or laptop computer. These cameras are operated from a central control room, where the video images can be monitored live or stored for viewing at a later date.
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.
As this new technology developed, the usage of CCTV systems spread rapidly. Its value for enhancing security was recognized. Consequently, surveillance cameras are installed in more and more public places. Today in the United Kingdom, for example, CCTV systems are installed to monitor auto and pedestrian traffic on roads, sidewalks, city squares, rail and bus stations, airports, shopping malls, and municipal areas.
It is common today for banks and retail stores to install CCTV systems to discourage theft, by recording evidence of criminal activity. A small business may install a CCTV camera in a prominent place so shoppers know that they are being watched. A larger business will usually make its cameras less visible by installing them in ceiling tile domes, smoke detectors, sprinkler heads, thermostats, clocks, or other concealing objects.
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.
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.
