Video bell and main power help

Hello, i have a ring 4 door battery bell.
The battery life is shocking so i want to make it mains power.
I don’t have a bell or the wiring so it will be a fresh set up.

What do i need to do.

I wanted to take the power from the outside light to power it.

But ive read i need a transformer? Is this right?

Hi @Claire2242. I’d first recommend reviewing the information and troubleshooting steps we have on unexpected battery drain here. If you want to hardwire your Video Doorbell 4, it requires a transformer and doorbell wiring, and it will provide a trickle charge to help extend the time between charges.

We have a step-by-step guide on installing a Doorbell 4 with an existing doorbell circuit here. A transformer with a voltage of 8-24 VAC, 40VA max, 50/60Hz is required. We also have the Plug-In Adapter which can be used for continuous power. Since you do not have an existing doorbell circuit, this may be a better option for you.
