Does the Eufy S330 need existing wiring?

Yes. It is a wired doorbell that runs on 16-24V doorbell power and needs a 30VA transformer. It will not work on battery alone.

Is there a monthly fee for recordings?

No. The S330 stores clips locally, so there is no subscription for basic recording and playback.

Does it work with a Eufy HomeBase?

No. The S330 is not supported by HomeBase and stores footage on its own.

What is the second camera for?

The lower camera points at the ground in front of the door, so you can see packages and the doorstep that the main lens misses.

Does it work with Alexa and Google Assistant?

Yes. You can view the live feed and get alerts through Amazon Alexa and Google Assistant devices.

Does it detect people or packages specifically?

No. It sends motion-only alerts, so any movement in its zones triggers a notification.

Our take on the Eufy S330

The Eufy S330 is a wired video doorbell with two cameras: one facing visitors and one aimed down at the doorstep. It records 2K HDR video and needs existing 16-24V doorbell wiring, so it replaces a wired chime setup rather than running on battery. Local storage means no subscription for clips, which sets it apart from Ring and Nest doorbells that charge for recording. Buyers like the dual view for packages and the sharp picture; some find setup and app alerts fiddly.

What reviewers say

4 / 5100 ratings
