A wireless door alarm can be an optional feature in your home security. This is definitely one of your first lines of defense against possible intruders. If you are still at the point of considering this option, it’s important for you to find out how it works exactly.

A door alarm is typically attached to the frame of your home’s entrance. It can run on batteries or it can be plugged to an outlet. Alternatives to wireless alarms are those that can be hard wired into your home wiring. Its mechanism is simple. It detects possible intrusion when its magnetic panels are misaligned. In more advanced models, motion sensors are incorporated. When a wireless door alarm is tripped, it sends out a siren to alert residents. Signals could also be sent to a homeowner’s monitoring unit or a third party facility.

When used as a security device, it is always best to get an alarm as part of a package. Ideally it should be part of a third party monitored package. Alarms used alone are just noisy deterrents. If you are unlucky enough to get a burglar who just isn’t afraid of noise, you can at least rely on external help from a monitoring facility.

Door alarms are often used as more than just burglar deterrents. A wireless door alarm can also help parents keep track of young kids who may have a tendency to wander out on their own. Caregivers can also benefit from this piece of equipment as they look after elderly or mentally ailing patients.
