That downward lens keeps parcels on the doormat in frame, and on top of it the E340 adds package alerts, familiar-face recognition and color night vision, all without a subscription, and owners review it more warmly. Otherwise the two are close siblings: 2K video, a quick-release battery or wired power, 24/7 history, quick replies, IP65, 2.4 GHz Wi-Fi, Alexa, Google Home and Home Assistant support, and an indoor chime sold separately on both. The Eufy Video Doorbell C31 (with Battery Pack) keeps one practical edge, a microSD slot of up to 128GB where the E340 has a fixed 8GB. Buy the Eufy Video Doorbell E340 for most front doors, and the Eufy Video Doorbell C31 (with Battery Pack) only if you want more room for local recordings on a card.

What the differences mean

Package camera

The Eufy Video Doorbell E340 has two cameras, one of them aimed down at the doorstep, and sends package alerts. The Eufy Video Doorbell C31 (with Battery Pack) has one camera and no package detection, so a parcel at your feet can fall out of frame.

Smart alerts

Both detect people. The Eufy Video Doorbell E340 also recognises familiar faces and packages, without a plan.

Local storage

The Eufy Video Doorbell C31 (with Battery Pack) takes a microSD card of up to 128GB. The Eufy Video Doorbell E340 records to a fixed 8GB inside, which a busy porch fills faster unless you add a Eufy HomeBase.

Night vision

The Eufy Video Doorbell E340 records color night vision, so clothing and cars keep their colors after dark. The spec sheet of the Eufy Video Doorbell C31 (with Battery Pack) lists no color night vision, though its owners call the picture good by night too.

Size, power and chime

No real difference: both are around 150 mm tall, run on a quick-release battery or wiring, and need a chime sold separately or a smart speaker to ring indoors.

Which one to buy if

What owners say

Owners of both Eufy doorbells chose them to avoid monthly fees, praise a clear 2K picture and an easy install on existing wiring, and both groups complain about a bulky body, an indoor chime sold separately and battery life that is adequate at best. Eufy Video Doorbell E340 owners single out the head-to-toe view that shows packages on the ground, accurate delivery and person alerts and helpful positioning guides; their gripes are a clunky app and occasional false package notifications. Eufy Video Doorbell C31 (with Battery Pack) owners like recording straight to microSD and years of trouble-free experience with the brand, but report recharging roughly monthly with no low-battery warning, slow notifications and live view, and previews that fire before the person is in frame.
