Different Uses for Closed-Circuit Television

Since its invention as a way to monitor V2 rocket launches in the Second World War, closed-circuit television has had a variety of uses (and a number of opponents) in modern society. This technology, which uses a single channel to transmit television signals and does not broadcast the television signal to outside detectors, aids law enforcement and science.

Closed-circuit surveillance

Most people think of security cameras when they consider closed-circuit television and its uses in Western culture. For decades, banks have adopted closed-circuit television as a way to discourage robberies. A well secured, highly monitored bank gives great incentive for potential criminals to change their plans. In Britain, closed-circuit cameras monitor the streets and present an additional obstacle to potential felons. The idea that the government can always monitor, record and punish wrong actions is attractive to many citizens, as well as effective in limiting crime - but it has its opponents as well, especially in libertarian and privacy-centered activist groups.

Scientific monitoring

Closed-circuit television aids scientists and engineers greatly. By setting up these cameras, scientists can monitor habitats or environments where human beings would find themselves in pressing, physical danger. This means scientists can measure volatile chemical reactions, launch rockets, test viruses or monitor quarantined patients without subjecting themselves to the perils of direct, physical contact.

Although closed-circuit television has a checkered history and is sometimes opposed for its adverse effect on privacy and civil liberty, its gifts to society are indispensable. As Western culture moves into the future, it is sure to continue its dependence on closed-circuit television for law enforcement, experimental and scientific purposes.
