The ABCs of a Home Burglar Alarm
You undoubtedly feel safer in your home knowing you have a home burglar alarm system, but how exactly do they work? Although there are a variety of alarm systems on the market, most work in roughly the same way.
-Electric Circuit: Optimal for guarding the perimeter of a house, electric circuit systems send a flow of electricity around your home. Opening a door or window breaks the flow and triggers the alarm.
-Motion Sensor: If the electric circuit fails to stop an intruder, this motion sensor system is best for detecting somebody inside the house. Basically, a box emits microwaves and detects when the energy bounces back. If somebody enters the room, the pattern of reflection is disturbed, and the alarm is sounded.
When an alarm is triggered, any number of alerts can be activated. There might be flashing lights, a loud sound, or an automatic call made to the police.
Like anything, a security system is not absolute. Still, as a homeowner, you can understand the workings of a system and choose the best option for your home and family.
