Security Cameras

Security Cameras have become widespread in many countries. Whereas before they appeared only in banks and at the high security areas, they are now entering public places such as malls, streets, stadiums and transport. Many people feel this affects their privacy. Apparently, there are advantages and disadvantages to the use of such devices.
Surveillance cameras have several benefits. An obvious benefit is that the police can catch criminals in the act, thus reduce crimes. This will make the streets safer for ordinary people. A more important point is that criminals, particularly young offenders or petty criminals will be deterred. They will not be tempted to carry out crimes, and thus society will be a lot safer. Cameras are cost-effective and unobtrusive. Authorities do not need to spend large amounts of money on police.
However, security cameras are far from being a perfect solution. The biggest objection concerns privacy. Many people feel that they should be free to travel or move around a shop, a mall, a street or a country without being photographed or recorded. They feel that being watched constantly is like being in jail. Another point is that although the police say that only criminals have something to fear from the cameras, many people do not trust governments with too much information. Corrupt authorities could use information in the wrong way or twist it to victimize some groups. Thirdly, cameras and computers can make mistakes.
In conclusion, although there are definite advantages to using surveillance devices, we need to balance the need for security with respect for individual's privacy and
