Wired alarm or wireless alarms? What to go for...

Updated: Dec 29, 2021

We see this question being asked a lot - 'Which is the best, wired or wireless alarms?'

Domestic security alarm sensors or PIRs as many people know them need to signal to a central control unit within the house, and that signal path can be via a cable or it can be sent by radio waves, i.e. wireless.

There are advantages associated with both types of system and the one you choose will depend on your own circumstances.

Wireless sensors are battery powered and thus they’ll need a battery change now and again to keep the system operating properly. Wired sensors are mains powered, being individually fed a low voltage supply from the main panel, so that’s an obvious maintenance advantage, although wireless sensor battery changes usually take minutes and the batteries themselves should be readily available and inexpensive. Are wireless sensors as reliable as wired ones? The short answer is yes, and many established alarm installers and manufacturers will offer both types. In an industry where reputations matter, you certainly need to trust your portfolio of products.


Wireless sensors can be fitted anywhere within the 200m signalling range, so the security of detached garages, sheds, summer rooms and out houses can all be integrated into the security alarm in the house. Wired alarms are less flexible, though hybrid systems, using a combination of wired and wireless sensors, are available. Adding to a Yale Smart alarm system, for example, could not be easier, up to 40 accessories can be added - so as your circumstances change, so can your security system.


Using advanced anti-hacking firmware, today’s wireless alarms are extremely resistant to electronic interference, whether that’s malicious or accidental.


The cost to install security alarms has fallen in relative terms due to competition and improving and evolving technology. Wired systems may cost a little less to buy but this may be offset by longer installation times due to the cabling required and unsightly wires from hard-wired alarm systems routed through ceilings in a pristine house may not add to the aesthetics of your beautiful home.

Domestic wireless alarms are usually fitted within 2 or 3 hours, without the need to push wires around brick cavities, under floorboards and around door frames.


And with no cables to worry about, taking your wireless alarm with you when you move house is simple and may save you hundreds of pounds in your new place.
