雅思写作提纲：在公共场合安装监控器

 　　十五、在公共场合(超市)安装监视器

　　1、安装监视器的优点：利用监视器可以帮助警察catch criminals，thus reducing crime. a camera is more effective than security guards. 警察和保安不可能全天24小时工作，而camera will not feel tired.而且它更objective，sometimes our eyes might deceive us，while a machine can exactly record what happens，it can prevent much unnecessary embarrassment¹. Frighten off the criminals and reduce potential crime.

　　2、缺点：Critiques about installation of surveillance typically look at the infringement² of people‘s privacy. Being photographed and recorded by the camera，很多人feel uncomfortable and no privacy.特别是女性，有些人可能会将camera获得的资料用于illegal use.
