There are many advantages of closed-circuit television (CCTV). One of the advantage would be, during a crime scene, all the actions by the robbers would be recorded down. The robbers could not lie as whatever that is recorded would be the truth. The CCTV could be put outside someone's home to record anyone's action if someone would want to do the family harm. CCTVs are also put in markets to stop thefts from happening. A CCTV is like a human with a super powered memory. It is put at a certain location to let people know that someone is looking at them so that they would not commit any crime. It is also giving the police an easier job to catch hit and run cars as sometimes these CCTVs can capture the numbers on the number plate.
