Wireless Home Security
Wireless home security alarm systems are very popular with DIY enthusiasts. A wireless
alarm system is relatively straightforward to install as it needs only minimal hardwiring.
Typically, a wired alarm system should be left to a professional whilst a wireless
system can be easily installed by a DIY’er.
Generally, a wireless system consists of a control panel, siren and devices such
as PIR sensors, window/door shock sensors, smoke alarms etc... Every wireless security
component has a built in radio transmitter/receiver to enable it to communicate
with the control panel unit.
As the components of this system communicate wirelessly, it is easily possible to
move the components around the home without having to change any wiring. Its also
very easy to add new devices such as additional PIR sensors and smoke detectors.
There are however, limitations as to how many devices it can support.
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 wireless doorbells or baby monitors, might impact on the alarms effectiveness,
but these issues have been eliminated by the leading manufacturers.
To summarize, the main benefits of a wireless alarm system are:
- quick and simple to install by a DIY’er thus 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. drilling, removing floorboards, re-plastering etc.).
- sensors and devices 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, if a property is extended or the level
of security or fire protection needs changing.
There are a number of downsides to a wireless alarm system. Each device will run
on batteries so these will need to be regularly checked and replaced. A more sophisticated
alarm system can inform of a low battery device via its control panel display. Fortunately,
most devices can run in “sleep” mode when not needed, thus conserving battery life.
Be aware that poorly charged batteries may result in false alarms to be triggered.
Some materials in your property may impair (or even disable) a device’s ability
to communicate with the control panel. Thick concrete walls and iron/steel work
will not help the device communication. Also long distances could prove a problem.
