Closed Circuit Television

Closed circuit television has been used for many years by government bodies and security agencies to monitor and take care of buildings, houses, and streets, both interiors and exteriors. These devices are used to capture on video anything and everything that happens in the monitored areas. CCTV is used to detect any potential criminal activity and to keep places safe. These cameras are often seen on street corners or in building taping all that is happening, cameras are also installed at some traffic signals.

The closed circuit televisions are a popular choice of surveillance equipment as many can be connected to one network. That is, if there are many cameras installed at strategic locations for monitoring either outside or inside a complex any area can be viewed from one location. With this kind of surveillance, an owner can spot an intruder and have the law enforcement agencies on the scene much before the intruder is even aware that he has been spotted.

These cameras can be used in conjunction with any type of security device these days as long as all can be connected to ca common network. They can be programmed to begin recording at a particular time and continue until a code is entered to stop, it can also be programmed to automatically contact law enforcement if it detects a threat. These are of course more advanced systems.

Initially when this technology had just made its presence felt, it was expensive to have and only large organizations or government bodies could afford to have closed circuit televisions. But now with the advancement of technology even home owners and small businesses can utilize the advantages of these cameras. Since all these devices are able to be connected to networks, a business owner can monitor all activities in real time if he chooses to from anywhere overseas as well.

Other technological advancements in close circuit televisions are numerous, some of the most notable ones however are infrared sensitivity and wireless cameras, and these can also have motion sensors that begin recording as long motion is detected but does not record and use unnecessary space otherwise. Something called Pan Tilt Zoom as the name suggests pans in on a target, adjusts itself vertically or horizontally and zooms in at the same time.

Anything that is recorded on these cameras can be presented in a court of law as evidence against a burglary, or any criminal activity, many burglars and kidnappers have been apprehended and jailed quickly due to the proof provided by these cameras.

These are strong deterrents of unlawful activity and research has shown a 21 per cent reduction in crimes due to the installation of these closed circuit cameras. It can be argued that the places that have cameras raise the potential danger of crimes in other areas that do not have the facility but the presence of a camera on any property always causes an intruder to reconsider breaking and entering.
