CCTV narrowly wins because it offers all round security. Like a burglar alarm, its very presence is a brilliant deterrent and should prevent all but the most hardened and determined burglar. Where they differ their use during and after a burglary. A good noisy alarm might discourage burglars to stay too long in your house but they don’t offer any help to catch the offenders after the crime. CCTV however can be handed to police who can use it to help trace the culprits
