CCT surveillance cameras are very useful as in they help to cut down the crime rates as these cameras can capture facial images and the police can trace criminals much easy than before. Some more advance cameras can even "hear" gunshots and even detect what gun is used, and further more, it can face to that direction so it can capture what is happening on at that area and hence is very useful to bring criminals to justice.
