Dual Cameras with Delivery Guard

The eufy Security Video Doorbell E340 combines a front-facing camera with a downward-facing unit to monitor visitors and packages at the doorstep. It connects wirelessly to the included HomeBase S380 hub and operates on a rechargeable battery pack. The system supports Alexa and Google Assistant for voice control and stores recordings locally with no monthly fee.

Battery or Wired Power Options

Installation is flexible because the doorbell works with existing low-voltage wiring or runs on the removable battery pack. The battery fully charges in 5 hours and can be swapped with a spare to avoid downtime. An IP65 rating protects the unit against dust and water jets in all weather conditions.

2K Resolution and 99.9% Facial Recognition

The front camera captures 2K Full HD video with color night vision up to 16 ft using a dual-light system. BionicMind AI provides facial recognition that filters alerts and improves accuracy to 99.9% over time. Local storage starts at 16 GB and expands to 16 TB for continuous recording.

Questions about this item

How do I confirm the E340 doorbell is working correctly after setup?

The eufy Security app shows a live 2K feed from both the front-facing and downward-facing cameras, sends instant push notifications with thumbnail previews when motion is detected, and lets you test two-way audio and the 6 Quick Replies feature.

What comes in the box with the E340 bundle and what must I buy separately?

The bundle includes the battery-powered E340 doorbell with dual cameras, the HomeBase S380 with 16GB built-in storage, a rechargeable battery pack that charges in 5 hours, and mounting hardware; no separate storage subscription is needed.

Which version of the E340 should I choose for local recording capacity?

The included HomeBase S380 provides 16GB of built-in local storage and supports expansion up to 16TB, so you can start recording immediately and add a drive later if you need more space.
