How to Choose an Alarm System
Alarm systems come in all shapes and sizes; you can build a simple one yourself using common household objects, or spend hundreds of dollars on an elaborate system containing the latest technological advances. Regardless of the system you choose, it needs to provide reliable coverage for your entire house and give you a feeling of security whenever you activate it. You can aid in that process by determining your specific needs. Does this Spark an idea?

Measure the size of your house, including all of the rooms you want covered. An alarm system needs to possess a range--either through radio signals or wiring in the walls--which covers all of that space.

Count the number of entryways into your house, including doors, windows and alternative access points. Your alarm system needs to include components for all of them if you want it to work properly. Pay special attention to ground floor entryways, though second or third story access may merit consideration as well.

Think about places inside your home which you may want to cover with motion detectors. Most alarm systems include at least a few motion detectors designed to monitor wider areas. You want to place them in rooms which contain valuables, centralized rooms which a burglar may have to pass through, or "choke points" such as stairways and hallways.

Decide whether you want to used a wired system or a wireless system. Wired systems rely on electronic cables connecting each component, which means you'll likely need to get it installed by a professional. Wireless systems depend on radio signals or similar methods to link the various sensors to the central control system. You can mount and dismount them yourself using only a screwdriver--rendering the system portable if you ever want to move--but the components usually rely on batteries, which you will need to monitor and replace periodically if you want to keep the system functional.

Think about whether you want a security company to monitor your alarm system. Non-monitored alarm systems may emit a loud noise and the most sophisticated models will dial 911 and play a pre-recorded message, but a security firm means a live person monitoring your home and taking any necessary steps when the alarm is triggered. Security services usually charge a monthly fee, which you should factor into your budget accordingly.
