Ring’s sensors operate on battery power, the keypad and base station come with AC adapters, and the Z Wave range extender plugs directly into an AC outlet. All three of those components have battery backup, so the system will continue to operate in the event of a power outage. The base station
connects to your home network via hardwired ethernet or Wi Fi. A Ring Protect subscription activates an LTE module in the base station that will keep the system connected to the internet if your broadband connection goes down. You can even run the keypad on battery power full time if you choose, since most homes don’t have AC outlets right next to doors. An LED will tell you when the battery needs to be charged.
