CCTV Systems – Symbol of Security and Safety

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 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.

In addition to fighting crime, modern CCTV systems can perform a wide range of functions from image enhancements for the visually impaired to broadcasts of pay-per-view sports events. CCTV has many scientific (medical) capacities, including medical imaging, microscopy, and robotics. Other commonly used forms of CCTV are live video presentations used for special events, such as, concerts, sports events, conventions, and interactive teleconferences.

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.

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.

It is agreed universally by experts and laymen that the incidences of theft and vandalism are reduced by the mere presence of CCTV systems. Persons with criminal intent realize that they are more likely to be apprehended if there is a camera watching and recording their actions. To take advantage of this affordable and practical technology, many homeowners are installing CCTV cameras in their homes for added security for their families.

With the significant number of benefits of the CCTV systems, it is not surprising that the use of this technology has increased tremendously in recent years. In all areas of daily living, CCTV systems will continue to play a major role in protecting public safety.
