The dual-camera layout genuinely solves the dropped-package blind spot that single-lens doorbells have, and the built-in 8GB storage removes the subscription question entirely.

Overview
The eufy Security Video Doorbell E340 (model T8214) pairs a front-facing camera with a second, downward-angled camera so packages left flat on the porch stay in frame alongside a head-to-toe view of visitors, all recorded to 8GB of built-in storage with no subscription.
Most doorbells only aim at head height, which means anything set down on the ground can go unseen; eufy's answer is a dedicated downward camera running alongside the main one. Storage is built into the unit itself rather than requiring a card or a cloud plan, and the doorbell can run wire-free on a swappable battery or hardwired for continuous trickle charging.
- Dual cameras: head-to-toe plus downward package view
- 8GB built-in local storage, no subscription
- Wireless swappable battery or wired trickle charge
- Color night vision to 16ft (5m)
Who it's for
Suits anyone whose main frustration with a single-camera doorbell is missing packages set on the ground, and anyone who wants recording without a monthly fee. Less relevant if there is no porch delivery activity to track, or if an existing eufy HomeBase or chime is not already part of the setup.
Pros and cons
- Second downward camera catches packages the main lens misses
- 8GB of built-in storage with no subscription needed
- Swappable battery avoids downtime while charging
- Color night vision rated to 16 feet
- No microSD expansion beyond the built-in 8GB
- Full chime function needs a separate eufy HomeBase
Performance notes
The front camera frames a visitor head to toe while the second, downward-angled camera watches the ground for anything left at the door, with both recording to the built-in 8GB emmc storage rather than a card or subscription. Color night vision uses eufy's dual-light system for a stated viewing distance of up to 16 feet, and the doorbell runs wire-free on a quick-swap rechargeable battery or hardwired to a 16-24V source for continuous top-up.
