A bit about alarm systems
Alarm systems have been around for decades. From your simple car alarm that sounds off even if your vehicle is simply rattled to the more complex alarm systems installed in houses and office buildings – these devices made our life better. Safer. There are alarm systems that can be installed even into motorcycles these days. Some alarm systems are so small ad yet so powerful that they will fit in the tiniest of spaces ad still manage to give out a pretty loud sound. But modern alarm systems are all about networking.
Say you have a home and say you want to protect that home at all costs. It is all about your wife and children and your belongings. You ca install alarm systems to protect your house. And by alarm systems we don’t mean only your door and windows. You can install alarm systems to guide your garage and even the dog entrance. Most modern alarm systems rely on a central operating unit that is somehow tied to a network coordinated by a security company. You make a contract with such a security company and they will add you to their monitoring list. Such security companies supervise over hundreds of households, each equipped with alarm systems of various shapes and sizes. If the alarm is triggered the security company will phone you using the umber you gave them and verify that everything is in order. If someone from your family fails to pick up and answer the phone, then the next step is calling the local authorities that will probably send a patrol car to your house.
Modern alarm systems can make use of motion detection sensors that are triggered whenever a moving object crosses their path. These sensors can be refined as to not go off whenever a bird or a stray cat happens to pass in front of your door.
