Wireless Security System Overview

Have you ever watched a horror film where the villain snips the wires to a telephone or home alarm? The scariest part is realizing that, despite your home's security system, it could happen to you. In order to truly protect your home and family against the threat of break-ins, you need to invest in a wireless security system.

These wireless burglar alarms use radio waves to communicate with other components instead of using wires. The potential burglar cannot figure out how to cut wires to disable the system, so gives up.

The two main types of wireless burglar alarms are unmonitored and monitored. If an intruder is detected, unmonitored systems sound a loud alarm that is audible in the home and for a short distance outside. If you live in the countryside, these systems are not ideal, because if you are not at home, neighbors may not be able to hear the alarm, so no one will know about the break in. Monitored services, on the other hand, detect a break-in and then send a signal to security company staff, who determine whether it is a real burglary, and then call the police.

All wireless security systems include a control panel. This is the "brains" of the system, usually located in a closet or in the basement. The control panel receives all wireless communications that are sent by magnetic switches and motion sensors located throughout the house. If a suspicious entry or movement signal is received, the control panel will sound the alarm or dial the security company's central monitoring system.

Small, inconspicuous magnetic contacts are attached to windows and doors. They include two parts, a magnet that is placed on the window or door, and a switch that is placed inside the door jam or window sill. They work very simply: if the distance between the switch and the magnet increases, which would happen if the door or window were forced open, a signal is sent to the control panel, which sounds the alarm.

Large open spaces such as hallways can be equipped with wireless body sensors or motion detectors. Infrared motion or body heat changes are detected and a signal is sent to the main control panel. The panel gauges whether the movement is a person, and then sounds the alarm or alerts the monitoring station staff.

To enter or leave your home, the wireless security system must be deactivated or activated. You simply enter the password on a keypad near the main entrance to your home, making setting the alarm easy to do. Remote control devices also come with some systems, just like car alarms, so that owners can operate some features from a distance. Some systems allow owners to switch lights off or on remotely, giving the appearance of a home that is occupied.

Some wireless security systems also come with cameras, which can be all mounted or hidden. The cameras connect to a control panel and a recording device, such as a VCR. If an intruder is detected, the cameras record the home scene automatically. Some packages also include camera monitoring by security staff at the alarm system company.

A home security system is a good idea for protection and peace of mind. But for the highest level of security, consider a wireless system as the best choice, because of the enhanced features offered.
