United Kingdom is one of the countries, where the street cameras or also known as CCTV (Closed-circuit television) are broadly used to control what is going on. This method of surveillance has its both advantages and disadvantages.
On one hand, it saves time and money. If there is a crime, the police officers need to check the recordings from a particular camera and see what have happened without the need to look for any evidence or witnesses. In this way it prevents from any human error and somebody being caught my mistake.
It also makes people think what they are doing and responsible for their actions. When you know that somebody is watching you, you usually think before you do something especially if it is something illegal.
CCTV makes us feel safer. However, to gain security and safety we lose a bit of our privacy. There are people who don’t want to be recorded and watched.
In order to be efficient the CCTV cameras should be watched by authorised people. Since there are so many cameras across the country it is impossible to track all of them. Also there have been several cases of people stocking other people without their knowing using CCTV cameras. ( BBC report)
Moreover, everything is computer-based technology and there is a possibility of information loss if there is a computer failure or crash.
As everything else, CCTV has its strengths and its weakness. Its efficiency depends on the way it is used and people who use it.
