eufy Security Video Doorbell E340 (Battery Powered) - Dual Camera 2K

In this review of the eufy Security Video Doorbell E340, the bottom line is simple: it suits homeowners who want clear, no-subscription doorstep video and extra reassurance from a dual-camera design. The E340 pairs a front-facing camera with a downward-facing camera to capture faces and package drop zones, and its 2K Full HD imaging and color night vision make it easy to identify visitors day or night. Setup is straightforward in battery mode, and the option to use wired power for continuous topping up adds flexibility.

Key Features

• Dual Cameras: Two cameras work together so you get a focused view of people and a second downward view that captures packages and the ground directly in front of your door.
• 2K Full HD Clarity: Higher resolution recording reveals more facial and package detail than standard 1080p, helping with identification at the doorstep.
• Color Night Vision: The dual-light system and improved processing reduce blur and provide clear color views up to about 16ft (5m) at night.
• Battery or Wired: Install quickly using the removable battery for easy swaps, or connect a 16-24V >10VA power source to keep the battery topped up for long-term use.
• Local Storage, No Monthly Fee: Store footage locally with compatible HomeBase or chime options, avoiding subscription costs for basic use.
• Smart Assistant Compatibility: Works with Alexa and Google Voice Assistant and can pair with multiple eufy chime devices for home-wide alerts.

Who It's For

The E340 is best for homeowners or renters who value privacy and want a subscription-free option while still getting clear video and a dual-angle view that covers faces and doorstep activity. It fits locations where a quick battery installation is desirable or where moderate wired power is available to keep the battery charged.

It is less ideal for buyers who need an integrated cloud service or a system already tied to a different cloud subscription, or for those who require extremely long battery life without occasional recharging or swapping. Large properties that need multi-camera systems beyond a single doorbell should consider additional eufy devices or a dedicated multi-camera setup.

Pros & Cons

Pros

• Clear 2K video that improves identification of visitors compared with 1080p alternatives.
• Dual-camera layout fills blind spots and captures both faces and packages without blind areas.
• Color night vision with dual-light processing produces less blur and usable night detail up to 16ft (5m).
• Local storage and compatibility with HomeBase S380 mean no recurring subscription is required for basic recording.

Cons

• Battery life can be mixed in real-world use, so some users will want a spare quick-release battery.
• Wired mode requires the battery to remain installed and a compatible 16-24V, >10VA power source to top up the battery.
