Interior Siren October 28th, 2009
Every home security system should have an interior siren.
When a burglar breaks in, you want them afraid to proceed with their burglary. One of the things that scares them the most is the siren going off.
Most sirens are close to 100 decibels, and they will surely hear it. It tells the burglar two things: 1) these people actually have a security system, and 2) there is shortly going to be someone calling the police.
Common sense tells the crook, “Get yourself outta here!”, and you know what? They almost always do when the siren goes off.
Of course, the siren also alerts you, if you’re home and there’s a break-in. It’s scary, but better that you should know than have the burglar entering your home secretly.
Sidenote: Exterior (outdoor) sirens are not very popular anymore, for obvious reasons. Most time a siren goes off, it’s the homeowner accidentally setting off the alarm. Maybe we forgot it was armed and opened the door in the morning to let the dog or cat out. If a loud alarm blasted to the neighbors every time that happened, the neighbors wouldn’t be too happy. And they probably wouldn’t pay much attention to it anyway, as you’ll often see in the case of car alarms.
But the Interior Siren is a vital part of your burglar alarm. Don’t leave home without it. In fact, don’t STAY home without it, either
