Alarm systems
Alarm systems:
Burglars dislike noise: it attracts attention. A barking dog is a good
deterrent, but clever burglars have been known to carry snacks with
them to win over the watchdog. That's why a reliable burglar alarm is
a better choice.
It's important to have a thorough home demonstration of your alarm
system and to fully understand its features (e.g. a panic button).
