2K dual-cam  |  Battery or wired  |  2.4GHz Wi-Fi  |  8GB eMMC (90 days)  |  HomeBase 2 or 3

Overview

The eufy Video Doorbell E340 is eufy’s flagship doorbell, with two cameras — a front-facing camera for visitors and a downward camera for packages — so you see callers head to toe and any parcels on the doorstep. It runs on battery or wired power, records 2K with colour night vision, and stores locally with no subscription.

Key Features

Setup & Compatibility

Set up in the eufy Security app on 2.4GHz Wi-Fi. Run it on battery for a wire-free install or hardwire it for constant power. A chime can be a eufy chime, an Echo, the HomeBase, or your existing wired chime. Footage stores on the built-in 8GB or a HomeBase.

What’s New

The downward package camera is the standout — a second lens covers the doorstep that head-to-toe doorbells miss, so you can actually see deliveries on the floor.

Pros & Cons

Is Eufy Safe? The Privacy History Explained

Eufy markets its cameras on privacy and local, subscription-free storage, but it’s worth knowing the background. In November 2022 a security researcher found that some eufy cameras uploaded thumbnail images to the cloud even when cloud features were switched off, and that camera streams could in some cases be viewed without authentication by anyone with the right link. In January 2023, eufy’s parent company Anker acknowledged to The Verge that its cameras were not natively end-to-end encrypted at that time.

In January 2025 the New York Attorney General secured a $450,000 settlement with the companies distributing eufy products over these security findings, requiring them to strengthen their security programme and encrypt video in storage and transit.

Since then eufy has moved its cameras to encrypted-by-default streaming, applied AES-128 and RSA-1024 encryption on HomeBase 3, run third-party security audits and launched a bug-bounty programme. If subscription-free local storage and strong privacy are the reason you’re looking at eufy, it’s sensible to keep firmware up to date and review your cloud and notification settings. We think the current products are a reasonable choice, but we’d rather you knew the full history and decided for yourself.
