The past several decades have seen a dramatic improvement  in security aspect in modern cities. One of the most impressive thing is that there are so many cctv cameras or something like that in a great many of public places such as shops, bus or railway stations and so forth. there arouses a heated debate over whether we should use cctv cameras or not as it invades people’s right of privacy.

It’s undeniable that the utility of those sophisticated monitor machines is so necessary because they can help us to predict the unpredictable and potential dangers in public places as well as to protect people from them. To image, if there is no cctv cameras in these places where are crowded with people, it’s really hard for government to make these people save due to they cannot control the existance of some dangerous cases, such as terrorist attack, without monitoring digital machines. Furthermore, in order to prevent the commodities to be stolen by thieves in their shops, booth owners have no choice but to use cameras. In this sense, to make people saver and protect some rights of owners, cameras are essential in the public places.

In contrast, others held the opinion that the useage of cctv cameras in public places invades the right of people’s privacy. The reason why they protest to the utlity of monitoring machines is that the cameras in public places affect some actions of people due to their privacy right, however, if everyone keep his or her right and there are no cameras, that means all people are in the potential dangerous cases. Therefore, compared with the meaning of saving and protecting ourselves, we should discard some part of their privacy in order to avoid something dangerous.
