How Wireless Security Systems Work To Protect You
Alastair Lydeard
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.
There are two basic types of wireless burglar alarms available today. The first kind is activated by an intruder, but the alarm is only audible to the homeowner and nearby neighbors. These systems are less useful if you live in a rural area, and are not home when the break-in takes place. The second kind of wireless security system includes a monitor that will detect a forced entry, and then communicate that fact to a security company. The company staff will confirm whether it is a genuine break-in, and if so, will immediately call the local police.
The central brains of a wireless security system is the control panel, which can usually be located in the basement or a closet. Here, all the wireless signal data from the various magnetic switches and motion detectors in the home is sent. If the control panel detects a suspicious movement or door or window entry, it will sound the alarm or place a phone call to the monitoring staff at the security company.
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.
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 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.
If you've decided to invest in the peace of mind and security of a home security system, be sure to consider the added advantages of a wireless system. The advanced features and stronger security may make it your best choice.
