Wireless burglar alarms operate differently from their hard-wired counterparts in that the component parts (control panel, sensors and alarm) communicate via a transmitted radio signal, rather than electrical connections across the whole system. But beside this fundamental difference, the actual method for detecting intrusion remains the same.

In the majority of cases, this is based on motion detection using Passive Infrared technology (which works by sensing the increased body heat of an intruder), and sometimes magnetic sensors attached to doors or windows that will trigger an alarm when the connection is broken between the separate parts of the sensor.

So what are the real advantages of wireless burglar alarms? Essentially, the main benefits come from the absence of wires, including:

• quick and simple to installation, avoiding the costs of hiring a professional to do install the alarm;

• a lack of disruption (and potential damage) resulting from installing a hard-wired alarm (e.g. removing floorboards, drilling, re-plastering etc.);

• sensors that can be placed almost anywhere as location is not dictated by wiring issues;

• easily removed and re-installed alarms for individuals such as tenants in rented accommodation where landlords will not allow alterations;

• easily added additional sensors for example, in case a property is extended or the level of security needs changing.

Wireless burglar alarm technology is now widely considered to be just as reliable as that of wired technology, all due to recent developments. When wireless alarms were first introduced, there were some concerns that signal interference for example, from baby monitors or wireless doorbells, might impact on the alarms effectiveness, but issues these have been eliminated by the leading manufacturers.

It is important to note that wireless alarms will not suit all premises; limited transmission distances mean that wireless burglar alarms are better suited to houses and small business premises, rather than large commercial or public buildings.

The cost of wireless burglar alarms has been reduced dramatically over the years due to the technology has become more established, and prices compare very favorably to hard-wired alarms, particularly where installation costs are involved.

Wireless alarms are available to suit all budgets, with the range of functions varying according to cost. The most affordable devices are available for as little as £30 and perform basic but highly reliable functionality that usually consists of motion sensors that trigger an alarm and send a pre-recorded alert to a specified phone. More sophisticated wireless alarms include features such as:

• intrusion detection methods combining magnetic contact sensors and motion sensors

• added functionalities such as smoke, gas or flood detection;

• automated messaging via phone, text or email;

• telephone and panic alarm integration for elderly or disabled users;

• knowing the difference between a pet and a person and thus allowing pets to roam freely without triggering the alarm.

Not all wireless alarms are based on motion sensor devices. Some alarms can be triggered by the detection sound waves created by the forced entry into a building. This type of system works simply by plugging a single alarm unit into the mains – no other type of sensor is required anywhere else in the building.

Unfortunately, no one can predict that burglary rates will fall in future and as such, the demand for wireless burglar alarms is growing as consumers choose this cost-effective and hassle free way of protecting their homes.
