Intruder Alarm Systems
The idea of an intruder alarm is to simply try and deter a potential burglary occurring at your house, and to an extent it works a treat. After all if your house is alarmed and another house just up the road isn't then your house is a lot less likely to get targeted.
A burglar does not want any attention, he just wants to get in with as little fuss as possible take what ever he wants and leave to go on to the next house, if he triggers an alarm system it could obviously ruin his entire day, noise is his worst enemy because it attracts attention.
