Alarms can be either wired or wireless. Wireless alarms look nicer, are generally easier to install and can be removed more easily if you move house. They use battery-powered sensors that communicate with a control panel using radio signals.
Wired alarms tend to be cheaper but are more expensive to install, as wires have to be hidden and holes drilled for cable routing.
We at Remote Security Services only install wireless alarm systems as this is more cost effective and allows for a clean install. So you can have your alarm up and running in the shortest time without any mess.
