What is CCTV? CCTV or Closed Circuit Television is a video system developed for security at banks and casinos or places like that to try and prevent crime. Today you will also be able to find CCTV systems at homes as it is being used as Home Security for everyday surveillance. CCTV actually records what it sees and therefore, if a crime does take place the recordings made by the CCTV is the first thing the police will look at to try and find any leads. It just makes the public feel safer knowing that their car is parked in an area where there is CCTV surveillance or they are walking in a mall where there is CCTV surveillance.
These cameras are used for monitoring public areas, for recording of events, direct surveillance or deterrence of criminal activity. When used for monitoring public areas is comes in very handy if the police needs assistance in maybe needing to catch a criminal who has been caught on tape or detect various incidents or accidents. It also comes in handy when a previous offender has been barred from a certain area then the CCTV will make it easy for you to see whether this person is staying away like he or she is supposed to. It comes in very handy when it is recording around a big concert or an important meeting where security personnel have been put outside the building and you are able to contact them from the control room telling them that you saw something on screen which they will be able to investigate immediately and finally being used for direct surveillance where you are tracing a suspect for instance.
Where do you install these cameras? They need to be high up which will allow for the most coverage of a certain area. This way there is nothing that can block your view either. Also putting these cameras up high will prevent them being stolen as criminals might take them down. If you have the cameras outside of your building you can have one at the back and one at the front if you prefer or just one either in the front or at the back depending on how much security you require.
