The home security market offers a huge range of burglar alarm systems; some are suitable for DIY installation, but others require fitting by professional installers. There are two basic types: one sounds an alarm if someone tries to break into your home, while the other detects any intruders inside.
When you buy an alarm system, make sure that the alarm is audible over a fair distance. Anything with a sound level below 95 decibels won't be heard, especially if there is heavy traffic noise. Tell your neighbours you are installing an alarm and make sure you choose one with a bell that stops after about 20 minutes so you don't keep them awake all night.
Before you invest in an alarm system, make a thorough check of the security of the doors, windows and other possible access points to your home. Add lights to dark corners at the front and back door; fit window locks and good-quality door locks and make sure french windows and patio doors are also secure. Take advice from your local Crime Prevention Officer, and join (or even form) a Neighbourhood Watch Scheme.
