Closed-Circuit Television (CCTV) is used as a form of security in the modern world. They are made up of camcorders that are connected to some monitors, to notify the man behind the computer. The monitors are not situated in the open; so, all that is being done in front of the camera will be viewed in secret.
These CCTV surveillance Cameras are usually used in delicate places that need tight security like the casinos, shops, banks, army bases and so on. So also, in many industrial sites, these surveillance cameras are used to monitor the process of production, especially in the chemical industries, for processes of production which might be harmful to humans. For example, the interior of reactors, equipment used for the production of nuclear fuel and so on. An added advantage is that operators can also determine the temperature of these processes too by using cameras that are built with thermometers.
The first ever CCTV surveillance cameras were first stationed at the Test Stand VII, in 1942, located in Germany, Peenemünde to be precise. These cameras were used in place of film cameras to monitor how V2 rockets launch and take off. With this, identifying faults with the rockets were easier. Later on, the bigger rockets were built with CCTV cameras, and then pictures of different stages of the location of the rocket were transmitted back to earth using wireless links. The greatest advantage of CCTV surveillance cameras in this field is that they are used to monitor the launching of the rocket. It is so useful because no other person except the pilot can be at the launching spot due to some safety reasons.
Furthermore, CCTV surveillance cameras are usually installed inside and outside government houses and other government facilities, just for security sake. They can also be used to monitor a particular area. The CCTV surveillance cameras operate using transmission links from one terminal to another. Its advantage over other means of security is that it can work continuously over a long period. It has a control room in which the cameras can be explicitly controlled.
Sometimes, the installations of these CCTV surveillance cameras are made as a point of duty by law, most especially in government facilities and other big organizations. The CCTV surveillance camera is a perfect alternative to security problems all over the world.
In the modern day, CCTV systems have been made less expensive and very easy to install to the extent that they can even be installed in various homes. CCTV systems are much cheaper than they were before. They have not just caught up with, but also left other means of security behind, even the spy cameras. Over few periods of time, the CCTV surveillance cameras will continue to develop until they provide maximum security in the entire universe. CCTV security systems and security solutions would be so much available for security problems, both for small and smaller businesses.
