CCTV offers a faithful transmission of what is happening in a public space, providing footage that can prevent crime and identify illegal or criminal activities. For example, in a bank, the CCTV images may monitor the presence of a break during the night and the police can be notified that allows avoiding theft. On the other hand, if the theft has taken place, the images can reveal the identity of a suspect.
At airports or train and metro stations, these surveillance cameras can also be of great help. The images from the cameras of CCTV have helped in the search for people who planned the attacks in London 2005, and have been instrumental in solving many other crimes. CCTV also being used to control traffic on the roads and highways. The CCTV can point out the places where there is a traffic jam or an accident, allowing measures to be taken in a matter of minutes.

People are increasingly interested in keeping your property safe and so choosing CCTV to help do that.

However, the idea that CCTV can bring more security can act as a comfort that certainly outweighs the negative.

However, the "eye in the sky" all-seeing is still the icon of surveillance. For monitoring in many modern cities and buildings are often used CCTV. While monitoring can be a useful tool for the forces and security companies, many people are concerned by the issue of loss of privacy.
Surveillance is the practice of watching over a given terrain, its inhabitants, and their relations, commonly for the purpose of exercising instrumental control over that which is being watched. As such, surveillance is central to the establishment and maintenance of “scopic regimes” that enact power to order the world. From its inception as a discipline, and indeed even prior to its attainment of disciplinary status, geography has engaged with surveillance as both participant and observer (Coleman 2011, 325).
