What the differences mean

Where video is stored

The Eufy Video Doorbell C31 (with Battery Pack) records to its own microSD card, up to 128GB, and supports 24/7 history. The Eufy Video Doorbell S220 has no card slot and records only through a eufy HomeBase, which you need to own or buy.

Battery life

Eufy rates the Eufy Video Doorbell S220 for 6 months per charge. The C31's rating is not documented, and its owners report recharging roughly monthly, so on battery the S220 is the one you touch less often.

Quick replies

The Eufy Video Doorbell C31 (with Battery Pack) can answer visitors with preset messages. Automatic replies on the Eufy Video Doorbell S220 are not documented.

Weather rating

The Eufy Video Doorbell C31 (with Battery Pack) is rated IP65. The Eufy Video Doorbell S220 is listed as weather resistant without a published IP rating.

Which one to buy if

What owners say

Owners of both Eufy doorbells buy them to avoid a monthly fee and praise clear 2K video and an easy install on battery or existing wiring. Eufy Video Doorbell S220 owners single out long-term durability, near-flawless person detection with few false alerts and strong battery life; they warn that it needs a HomeBase, that two-way audio lags noticeably and that it occasionally misses an event or drops offline until the HomeBase is restarted. Eufy Video Doorbell C31 (with Battery Pack) owners like recording straight to microSD and popping the quick-release battery out to charge without taking the doorbell down; their main complaint is battery life that falls short of the claims, with no low-battery warning, followed by slow notifications and live view, a bulky body and no indoor chime in the box.
