It can also be left plugged into the microUSB power adapter if you have a plug socket where you want it mounted. The user-replaceable 3V lithium batteries in the contact and motion sensors should last about three years, while the rechargeable battery in the keypad lasts between six and nine months. A range extender is included in the kit, but each device works as its own range extender, so unless you live in a really big house or have thick walls and obstructions, you probably won’t need it.

The system uses the Z-Wave wireless protocol, not wifi, to connect to the various different components, reaching up to 76 metres from the base station. The whole lot can be done in about 15 minutes if you know where you want everything to go. Then it’s simply a process of pulling the battery tabs out of the various bits one by one and choosing where to put them.

Plug the base station into power and hook it up to your home network via ethernet or wifi. You’ll need a Ring account, and its app on your smartphone, which guides you through the whole process. Installation was surprisingly straightforward and easy. You can screw everything in place if you want or, as I did, simply stick the various bits in place with foam fixers. The Ring Alarm is a DIY, wireless solution, which makes it rental-friendly. Installing the contact and motion sensors was a doddle using either screws, the included foam fixing mounts or my personal favourite, Command strips.
