What is the difference between a wireless or wired burglar alarm

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.

While this type of alarm tends to be cheaper to install professionally, the alarms themselves can be more expensive. Wired alarm systems usually need to be installed by a professional, as the alarm wires will need to be hidden, so labour costs are higher.
