Eufy Video Doorbell C31 (with Battery Pack) vs Eufy Video Doorbell S220

The Eufy Video Doorbell C31 (with Battery Pack) is the stronger overall pick, working with Google, Alexa and Home Assistant, recording to microSD or a HomeBase, and adding voice replies, all without a required hub. The Eufy Video Doorbell S220 is cheaper and better rated with a durable track record, but it needs a Eufy HomeBase to work.

Whether you need a hub. The Eufy Video Doorbell S220 is the add-on version and requires a Eufy HomeBase to store recordings, while the Eufy Video Doorbell C31 (with Battery Pack) can record to a microSD card on its own and also supports Home Assistant and automatic voice replies.

The Eufy Video Doorbell S220 requires a Eufy HomeBase to function and store video. The Eufy Video Doorbell C31 (with Battery Pack) does not: it records to its own microSD card slot (up to 128GB), with a HomeBase optional for expanded 24/7 recording.

The Eufy Video Doorbell S220 is the more affordable and higher-rated of the two, with customizable motion zones and a strong durability reputation. The trade-off is the required HomeBase and its laggy two-way audio, so weigh those against the lower price.

Buyers who want a standalone, subscription-free 2K doorbell with a microSD slot, voice replies and Google, Alexa and Home Assistant support, without committing to a Eufy HomeBase to get started.

Budget buyers who already own (or plan to add) a Eufy HomeBase and value long-term durability, customizable motion zones and a 6-month battery rating, and who can live with laggy two-way audio and the required hub.
