The advantages:

Firstly, the surveillance would hinder, deter and prevent crimes from happening. Secondly, it would help the police in crime cases, track down the suspects and culprits. Thirdly, if you are a boss of a company, of course you do not want to pay your employees for slacking. The CCT surveillance would deter workers from slacking. There would be a lower crime rate with the 24/7 CCT surveillance.

The disadvantages:

With the CCT surveillance, it invades into people's privacy. It is a bit scary, if people do anything, their actions are track, such as where they go, what they do, etc. Secondly, it is a bit costly for purchase CCT surveillance. 

Let me state a scenario.

One day, if i were to install CCT surveillance at my home door, what is the effect?

Firstly, it will deter robberies.

Secondly, it would capture videos of people walking pass your house.

Thirdly, it would upset your neighbours. WHY?

Think for yourself. If you neighbour sees the CCT surveillance, they would think that you might be spying on them. Secondly, they would also think that you do not trust them. Neighbours are suppose to look out for one another.
