參考范文：

Nowadays, for the sake of public safety, security facilities, staffs and policies are overwhelming in urban areas. In my view, this trend brings more advantages than the disadvantages, and my reasons would be explored as below.

Apparently, the root cause of increasing crimes and violence in cities is the inadequacy of police supervision, so that installation of security measures in buildings and streets are an effective preventive means by which the safety of urbanites will be improved. Firstly, these measures, such as on-patrol police vehicles, can immediately catch out and stop ongoing illegal activities such as thefts, robberies and vandalism, thus reducing the rate of social crimes in open space directly. Secondly, the universal camera-based monitory system that is 24-hour available plays a key role of deterrent, which reminds the would-be criminals that they have no chance to escape from the supervising of police and the punishment of justice, no matter when or where they plan to committee a crime. Therefore, these potential law offenders would give up their evil desires. In addition to the values of preventing social crimes, the network consisting of omnipresent cameras and sensors also serves as a function of warners. For example, when there emerges a fire, the security system can provides alarm signals to both residents inside and firefighters, thus helping to save people’s poverty and lives.

However, I have to concede that demerits associated with setting more security devices should never be ignored, and the most worrying aspect is that this behavior violates the basic rights of citizens. In fact, no matter how useful these measures might be in terms of stopping social crimes, they inevitably offend the human privacy, because they automatically watch and record every movement and activity of people. Obviously, the strong supervision of police and monitor system is very likely to turn the living environment into a jail-like place, where every trip is traced and every private life is peeked. Expectedly, what urban residents feel is stress, discomfort, degradation of freedom and well-being, even unpleasure and anger about the government.

In conclusion, I believe it is worthy for a city to set up more security measures. Although there is a concern of freedom and privacy deprivation to some extent, this method can make great contributions to social-crime prevention, as well as a safer living area.
