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 wireless home security system is a burglar alarm that does not use wires to transmit messages; instead it uses radio waves to communicate. This leaves the burglar or the intruder clueless, unable to know which wires to cut to deactivate 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.

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.

If your home has large spaces such as hallways, you can equip them with a feature of the wireless security system called a body sensor, or motion detector. They use infrared motion or body heat detection to sense someone's presence, and send a signal to the control panel. The panel will determine if the threat meets its standards and if so, will alert the monitoring station or sound the alarm.

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 systems also use hidden or wall-mounted cameras that are connected to a video unit and VCR. All movement detected on the cameras is recorded by the VCR. Depending on the system, the cameras may be monitored by staff at the security 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.
