We now live in a world where we are all becoming much more aware of the fact that we are being monitored. It started with the Police using CCTV to monitor town centres and other high crime risk areas. This was done to enable the police to attend possible trouble spots quickly and, according to Home Office statistics, it was a great success. Crime rates in areas where there are CCTV surveillance cameras in operation have fallen dramatically. These cameras help the police not only to attend incidents quickly but also to see problems developing and to attend before an incident becomes too serious.
