How Wireless Security Systems Work to Protect You

The villians in many horror films have it easy. They just snip the wires leading to a telephone or home alarm system, and the system is rendered useless. Scary enough, but it is even scarier to think this could be true of your home as well. The answer is to protect your family and home against break-ins with a wireless security system.

A burglar alarm without wires is the simple explanation for a wireless home security system. They communicate with radio waves instead of over wires. Thus the burglar is unable to determine which wires to cut to disable the alarm.

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.

Throughout the home, inconspicuous magnetic contacts and switches are attached to doors and windows. These consist of two parts: a magnet on the door or window, and a switch placed on the door jam or window sill. They simply detect movement by noting an increase in the distance between the switch and the magnet, which only occurs if a door or window is opened or forced open. The switch sends a wireless signal to the control panel, which sets off 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.

Every wireless security system comes equipped with a keypad, which is used by the homeowner to activate or deactivate the system. The keypad is normally installed next to the entry door, allowing the owner easy access to arm the system when leaving home, and disarm the system upon returning. Remote keys, much like a car alarm, can also be used to operate a wireless alarm system. The homeowner can also use the remote controller to switch lights on from a distance, giving the illusion that someone is occupying the house.

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.

There is no doubt that any home security system can offer a certain degree of protection for your property, or even your life. However, for the highest level of protection, a wireless security system is your best choice.
