Close-circuit television or CCTV is the technology which transmits videos from mounted cameras to remote monitors, commonly for security and safety reasons. The transmission can take place either through cables connecting the video camera to the monitors or through wireless connection.
Developed first in Germany in 1942 to record the V2 rocket launch by German engineer Walter Bruch, the CCTV system was installed in main city streets in an effort to prevent crimes. Banks and stores followed suit, monitoring and recording the activities within the establishment. CCTV systems are now available for private individuals for the security of their homes and properties.
The CCTV system works by installing video cameras in strategic places that can give a wide view of the location. These cameras transmit and record these video footages to a remote monitor or monitors usually watched by security personnel.
CCTV video cameras are installed in many public locations. In banks, airports, subways, stores and malls, police and military facilities and even in the streets. These highly-crowded locations are hotspots for crimes like theft, terrorism and other acts of violence. Studies reveal that a criminal is less likely to commit personal crimes such as physical assault within the view or proximity of a camera. The fact that the suspect's details can be recorded in the cameras and can be used to warrant his arrest can greatly deter someone from committing an offense.
Whether the CCTV can actually reduce crimes is still being debated upon, but it has provided help in criminal identification. Recordings of the CCTV installed in shops can provide recognition to shop-lifters and burglars or clues to crimes done within the vicinity. Other than monitoring criminal acts, the surveillance systems are also being used to combat anti-social behaviours which include minor offenses such as littering, urinating in public, traffic violations, drunkenness and other public order offenses.
Although most linked with surveillance and security, there are other uses of CCTV. Electron microscopy, medical imaging and robotics are few other applications of this technology. Live on-site video footages for conferences, concerts and sporting events such as boxing and wrestling are also an application of the CCTV system, as these transmissions are broadcasted to small and specific areas.
The CCTV systems have many types. Some cameras capture images alone, while some can record sounds as well. The type of CCTV camera depends on its main usage. If the main purpose is for surveillance or traffic control, it is not required to have coloured cameras; black and white images actually have a better resolution. However, if the main purpose of the CCTV system is criminal deterrence and identification, a coloured system is essential.
CCTV can offer a sense of peace and safety to the everyday citizen; the knowledge that criminals and terrorists are unlikely to commit offenses when there are cameras around help calm people's minds.
Reducing crime rates and bringing peace of mind to citizens only shows how useful CCTV systems are to the modern world.
