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.
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.
There are two kinds of wireless burglar alarms on the market. The first type is activated when the alarm is tripped, but only the homeowner or neighbors can hear the alarm. This kind of system doesn’t make a whole lot of sense if you live in a rural area and are away from home when a break-in occurs. Another kind of wireless security system uses a monitoring device that will communicate a forced entry to a security company. When the alarm is triggered, the security company will check to see if it’s a genuine break-in; if it is, they will call immediately to dispatch the local police.
The control panel is the brains of all wireless security systems. It is usually found in the basement or in a closet. The control panel is where all wireless signals are sent from the various motion sensors and magnetic switches placed throughout the home. If a suspicious movement signal or entry is detected, the control panel sounds an alarm, or phones the security company’s monitoring service.
Magnetic contacts are attached to doors and windows. These small, inconspicuous devices consist of two parts: a switch installed inside the window or door jam, and a magnet placed on the door or window. If the distance between the magnet and switch increases, as in the case of forced entry, the control panel will receive a signal and sound 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.
Each wireless security system includes a keypad, which homeowners use to turn the system on or off. Normally, keypads are installed beside the main entry door, so that it is convenient to arm the alarm when leaving, or to deactivate it when returning home. Some systems also include remote devices, similar to a car alarm, which can operate several features. Homeowners can also switch lights on or off from a distance using the remote controller, to give the illusion that the home 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.
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.
