Quoting from Rafael :" The advantages of the CCT surveilance would be the decrease in the number of crimes comitted, because they know they are being watched by CCT surveilance."

I disagree with your comment as technology nowadays has enabled people to tap into the CCT surveillance and criminals such as theives may use this to their advantage to observe the environment and know the exact time to strike thier target. Therefore if CCT surveillance are to be put up in the neighbourhood, I suggest that they are well secured and given maintanence checks regularly.
