Our take on the Eufy Cam S4 Video Doorbell E340 4K Solar Camera

The Eufy Video Doorbell E340 is a dual-camera doorbell that pairs a 4K front view with a second low-angle camera aimed at the doorstep, so it shows faces and packages in one frame. It runs on a built-in battery and can be topped up by a solar panel, and it stores footage locally on Eufy's HomeBase instead of a subscription cloud. It suits homeowners who want package coverage without monthly fees. Rivals such as Ring and Nest offer similar dual-view or head-to-toe framing, but most charge for cloud recording, while Eufy's local storage and on-device detection are its main edge. Reviewers like the sharp 4K image and the package view, and note that the battery drains faster with heavy motion alerts and that the solar panel needs direct sun.

What reviewers say

Owners praise the clear 4K picture and the second camera that keeps packages in view. Many report solid detection and like avoiding cloud fees, but battery drain under heavy alerts and the need for sun on the panel come up often.

What people mention
  • Video qualityPraisedOwners call the 4K front view sharp and say night footage stays usable.
  • Package viewPraisedThe low-angle camera keeps deliveries in frame where a single lens would miss them.
  • Battery lifeCriticisedHeavy motion traffic drains the battery fast, and the solar panel only keeps up in direct sun.
  • Local storagePraisedFootage records to the HomeBase with no subscription, which buyers value.
  • SetupMixedInstallation is manageable, but tuning detection zones and notifications takes trial and error.

Questions and answers

Does the E340 need a subscription?
No. It records to a Eufy HomeBase, which is sold separately, so local storage works without a monthly plan.
How long does the battery last?
Eufy rates it for months of typical use, but frequent motion alerts cut that sharply. The solar panel extends runtime only where it gets direct sun.
What makes it different from a single-camera doorbell?
The second camera points down at the doorstep, so you see packages and faces in one view instead of a cropped or blocked shot.
Does it work with Alexa or Google Home?
Yes, it supports live view on Amazon and Google smart displays. Full recording and settings live in the Eufy Security app.
Can it be wired instead of battery powered?
It can run on existing doorbell wiring for constant power, and the battery keeps it working during outages.
Is the HomeBase required?
Yes for local recording and on-device detection. Without it you lose stored clips and most smart features.
