With modern technology, lesser manpower will be needed to monitor a large area using the CCT surveillance. For example, in the past, when there is no CCT surveillance, three to four people will be needed to patrol a large area but with the use of CCT surveillance, lesser manpower will be needed. CCT surveillance can be installed in any place and only one person will be required to monitor all these areas. CCT surveillance also has recording function. Depending on the user requirement, the records can be kept as long as possible. When needed, the footage can be viewed to see what had happened. This is very useful as it helps the police to look up for suspects and witnesses. It helps police to verify facts against what the suspect had claimed.
