The advantages of CCT are numerous. For example if a crime is committed, the CCTV cameras would be able to capture the criminals face and record down what has happened for investigation purposes. This will take a load of the policemen's back and make their job a lot easier. It can also be placed at ATMS to deter snatch thieves from robbing the frail and elderly. This is much more convenient and cost effective than stationing a police man. It can be used to identify crooks that try to rob the ATM.
