Some advantages are that people in places with it will feel much more secure than without it, as they would not be afraid of any theft stealing their things and they would not need to check their belongings constantly. The crime rate would thus definitely drop. People who want to commit crimes in those areas where CCt surveillance are present would certainly think twice. The police would also find it much more easier to find and catch anyone who commits crimes, through the CCT surveillance.
However, there are a few disadvantages. One of them is that it invades our privacy and some people do not like this idea. It is also quite costly and in a country like Singapore, the crime rate is not that high and I do not think it is needed.
