When the security sector booms, it is a really bad indicator that crime is on the increase. Close Circuit Security Cameras (CCTV) may help identify criminals but it is certainly not the first line of defence but rather the last form of deterrent. Burglar bars, alarms, electric fencing then CCTV and perhaps a firearm is the way to go. Two large vicious dog or a half a dozen of large snakes may also be the way to go, but for insurance purposes CCTV may a first have.
