Wireless Alarm Systems.

Wireless burglar alarms operate differently from their hard-wired counterparts in that the component parts (control panel, sensors and alarm) communicate via radio signals, rather than electrical wired connection across the whole system. Beyond this fundamental difference, the actual methods for detecting intrusion are common to both. In the majority of cases this is based on motion detection using Passive Infrared technology (which actually works by sensing the increased body heat of an intruder), sometimes combined with magnetic sensors attached to doors or windows that trigger an alarm when they are opened.


Wireless burglar alarm technology has developed significantly in recent years, and is now widely considered to be just as reliable as that of their wired counterparts. There were some concerns about wireless alarms when they were first introduced, mainly regarding signal interference (for example from baby monitors or wireless doorbells) - but these have been eliminated by the leading manufacturers. It is important to recognise though that wireless alarms will not suit every building; they tend to have a set transmission distance and are usually therefore better suited, for example, to houses and small business premises rather than large commercial or public buildings.


Sadly no one is predicting that burglary rates will fall in future – no wonder then that the demand for wireless burglar alarms is growing as consumers choose this cost-effective and hassle free way of protecting their property.
