Quoting from Ethan:"Thirdly, it would upset your neighbours. WHY?

Think for yourself. If your 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."

If I am the neighbour, I would be rather happy that he or she had installed a camera. When your neighbour installs a camera, he or she would instead look out for you. My family have personally experienced a break in but we did not have a camera.Fortunately, our neighbour next door had a CCTV and caught the thief on tape. By doing this, they have protected themselves and also helped us.
