The main goal of a home security system is to protect your home and family. Of course, this is just the start. You need to know how home security systems work, what they can do for you, how to set them up, and whether or not this is really the right idea for your home. Although every home security system serves the same function, there are many options that you have to consider when making a decision on what to buy.

Every home security system has triggers. The two main types are those that trip when motion is detected and those that go off when somebody breaks and electrical circuit. Before you buy a system you should become familiar with the pros and cons of both types of triggers.

A motion detector is a great way to detect somebody who is already in your home. These work by sending out radio energy and monitoring for disturbance. If there is any motion in a room the alarm is triggered. In turn, a signal is sent to the control box and the alarm goes off.

What about electric circuit home security systems? These are the simplest types of systems, which makes them one of the most common. Simply put, these do a great job guarding the outside of your home including entryways that a burglar may attempt to use in order to gain access to your home. There are two types of electric circuit alarms: open circuit systems and closed circuit systems.

With an open circuit system, when somebody opens a door, for example, the circuit is completed and the alarm goes off. On the other hand, with a closed circuit system the circuit remains closed when the door is closed. If the door opens, though, the circuit is broke and this triggers the alarm. As you can see, the theory behind both types of open electric circuit home security systems is the same.

There are many categories of home security systems. To start, single premise alarms are basic and meant to alert you of things such as a door opening or smoke in your home. Those who are looking for a basic solution should consider this option.

A local alarm system is meant to do one thing: sound an alarm when the system is triggered. Even though the authorities will not be alerted, this is usually enough to scare a thief away.

A telephone dialer system is exactly what it sounds like. With this, when the alarm is triggered the system dials a preprogrammed number. The security service is then contacted, and from there the police and/or fire department is notified.

The most expensive category is continually monitored security systems. With these, any time the alarm is triggered your security monitoring company is immediately notified. From there, a real person calls the police.

Now that you know how home security systems work it should be easier to decide which one is right for you and your home. Compare your many options before you make a final decision.
