Both pair a main 2K camera with a second lens aimed at the doorstep, both alert on people and packages and recognise familiar faces, and both store events on 8GB of built-in memory without a subscription. The Eufy Video Doorbell (Wired) S330 is the wired specialist: it adds HDR video for a backlit porch and installs on existing wiring with no battery to charge, but it wants a 16 to 24VAC transformer and, unlike the E340, records motion events rather than continuous 24/7 history. Neither includes a chime. Choose the Eufy Video Doorbell E340 for a door with no wiring or for colour footage after dark, and the Eufy Video Doorbell (Wired) S330 for a hardwired door that wants the most forgiving picture in harsh light.

What the differences mean

Power

The Eufy Video Doorbell E340 runs on a quick-release rechargeable battery or on doorbell wiring, which 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.

Night vision

The Eufy Video Doorbell E340 keeps colour after dark, which makes a face or a car easier to identify. The Eufy Video Doorbell (Wired) S330 switches to black and white once the light drops.

HDR

The Eufy Video Doorbell (Wired) S330 adds HDR to hold detail in a bright or backlit doorway. The Eufy Video Doorbell E340 records 2K without HDR.

Continuous recording

The Eufy Video Doorbell E340 records 24/7 to 8GB of built-in storage or a eufy HomeBase. The Eufy Video Doorbell (Wired) S330 records motion-triggered events rather than continuous video.

How close they are

Apart from power, night vision, HDR and continuous recording, the two are twins: same 2K resolution, same 8GB built-in storage with no card slot, same 2.4 GHz Wi-Fi, same Google, Alexa and Home Assistant support, and a chime sold separately on both.

Which one to buy if

What owners say

Owners of both doorbells describe the same head-to-toe, dual-camera view and the same relief at not paying a monthly fee, and both groups install them easily when the wiring is right. Eufy Video Doorbell E340 owners single out colour night vision, the freedom to hardwire it or run it on the quick-release battery, and the AI that flags deliveries and people, and their complaints centre on needing a separate chime, a clunky app and a wave of false package notifications. Eufy Video Doorbell (Wired) S330 owners single out the second camera that keeps the parcel in frame and the free package alerts, and they talk 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.
