Quick answer
Should I choose a wireless or a wired alarm?
Wired alarms are the most robust long-term option and ideal during building or renovation. Wireless alarms install quickly without chasing walls and are easy to expand. Smart alarms add app arming, notifications and camera integration.
Many homes use a hybrid panel – wired where cables exist, wireless elsewhere. We recommend what suits your property, not what is easiest to install.
