I agree with Wilson that CCTV surveillance can be used to monitor people and sometimes help to solve crimes. Since many people find it intruding privacy, a lot did not install the CCTV surveillance at home. I agree with Wilson that the CCTV surveillance is hard to maintain and the expenses will be quite high, even if you install the CCTV surveillance in your shops, the theif can just disguise himself and if he wants, he can just destroy the CCTV as it is very vulnerable, making you to fork out some money to repair it. Even if so, the CCTV surveillance is proved to help in lowering the crime rates so CCTVs can almost be seen in every single shop as shoplifters would not have a chance to shoplift stuff without getting caught.
