The general purpose of the CCTV is to prevent and reduce crime. In theory, this happens because of one or more of these reasons: A: Deterrence - potential burglars and thieves may see the camera and decide that a store in question is too much of a risk and therefore not a good target B: Prosecution - thieves and shoplifters may be caught on camera and this can help catch and prosecute them C: Fear reduction - if everyone knows that there is a camera, they may feel safer in or around your business, thus preventing potential criminals from attacking D: Monitoring and intervention - if there is a security guard monitoring the area through CCTV system, he or she may act on any suspicious behavior and thus prevent a crime from occurring. Security guards may also deploy employees to a suspicious spot or near a person detected on the monitors.
