Deterrants for households
Many burglars gain entry through an unlocked or open window or door. While the belief may be that a professional thief has targeted your home - in reality - it is more likely that the crime is opportunist, but not necessarily amateur.
Intruder alarms and other electronic security measures will provide an effective deterrent, but should be used in conjunction with - not as a substitute for - appropriate physical security.
There is a range of electronic security systems available to protect your home - from bells-only systems to fully monitored systems and CCTV. The type of system you choose depends upon your budget and the nature of valuables you wish to protect.
