What the differences mean

Battery or wiring

The Eufy Video Doorbell C31 (with Battery Pack) runs on a quick-release rechargeable battery and can also be hardwired, so it suits a door with no power. The Eufy Video Doorbell (Wired) S330 is hardwired only and wants a 16 to 24VAC transformer at 30VA or more.

Chime

The Eufy Video Doorbell (Wired) S330 includes a chime in the box, and it can ring an existing mechanical chime over the wiring. The Eufy Video Doorbell C31 (with Battery Pack) ships without one and expects you to rely on the app or an Alexa or Google speaker.

Package and face detection

The Eufy Video Doorbell (Wired) S330 adds a downward camera, package alerts and familiar-face recognition. The Eufy Video Doorbell C31 (with Battery Pack) has people and motion detection only, with no package or face feature.

Storage

The Eufy Video Doorbell C31 (with Battery Pack) records to a microSD card of up to 128GB or to a eufy HomeBase, so you can keep more and swap the card. The Eufy Video Doorbell (Wired) S330 has fixed 8GB inside the doorbell and no card slot.

HDR

Both shoot 2K and see in black and white at night, but the Eufy Video Doorbell (Wired) S330 adds HDR to hold detail in a bright or backlit doorway, and the C31 does not.

Which one to buy if

What owners say

Owners of both Eufy doorbells value the same core: local recording with no monthly fee, a clear 2K image and a setup that reuses existing wiring when it can. Eufy Video Doorbell C31 (with Battery Pack) owners single out the quick-release battery they can pop out to charge, the option to record to a microSD card or a eufy HomeBase, and the spare battery in the box, then warn that real battery life falls short of the claims, that live view and notifications can run late and that the body is bulky with no chime included. Eufy Video Doorbell (Wired) S330 owners single out the second camera that keeps the parcel in frame and the free package alerts, and they complain about fitting a stronger transformer and about detection that fires too easily until it is tuned.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
