Key Features and Capabilities

The eufy Video Doorbell E340 stands out through its pioneering innovations and comprehensive feature set:

Dual Camera Setup Eliminates Blind Spots

The E340 introduces an industry-first dual-camera setup to eliminate blind spots that exist with traditional video doorbells. 

It contains two cameras:

1. 2K Front-Facing Camera: Captures visitors clearly in high 2560×1600 resolution

2. 1080p Downward-Facing Camera: Monitors packages placed at your doorstep

Together, these cameras cover the entire entry area without any gaps from door to floor. They overcome the limitations of even tall head-to-toe doorbell cameras that cannot view areas directly underneath.

So you’ll always have eyes on visitors as well as delivered packages before they enter your home.

Human and Package Detection with AI

Sophisticated artificial intelligence automatically distinguishes between human visitors and packages.

The E340 sends instant alerts showing you whether a known person, stranger, or delivery has arrived. This smart detection prevents unnecessary notifications.

You even get alerts if a delivered package gets taken by a porch pirate. The doorbell’s two-way talk lets you communicate warnings in such scenarios.

Color Night Vision for Optimal Low Light Imaging

Standard night vision doorbells use infrared illumination which results in black-and-white fuzzy imagery.

The eufy E340 introduces color night vision capability through an industry-first dual lighting system containing warm LEDs in both top and bottom portions.

This adjustable dual lighting paired with advanced image processing algorithms enables the E340 to capture color video even in dark conditions.

It provides remarkably clear facial details up to an impressive distance of 16 feet away from your door. The color night vision ensures optimal visibility at all times.

Hybrid Power for Hardwired or Battery Operation

The eufy E340 offers two installation methods to suit any home:

1. Hardwired: Connect the doorbell wires directly to the existing doorbell wiring to enable 24/7 power. This eliminates charging needs.

2. Battery-powered: Run entirely on a built-in rechargeable battery pack without needing wires. This enables versatile placement anywhere.

The smart hybrid system uses wired power when available, but automatically fails over to battery when electricity goes out. So wired setups also get backup coverage during power outages.

The removable battery also makes charging convenient. Keep spare packs for quick hot swapping!

Local Storage without Subscription Fees

The E340 comes with 8GB of onboard storage to store video recordings locally. This removes the need for any monthly cloud storage subscriptions. With the E340 video doorbell without a subscription, you can avoid ongoing fees and still enjoy smart doorbell features.

If 8GB feels limiting, simply insert a microSD card up to 128GB for tremendous expanded capacity. All videos remain encrypted and securely accessible through the eufy app.

You get full functionality like notifications, and instant video playback, without incurring hidden subscription costs. This makes eufy an extremely cost-effective and transparent connected device platform. 

Quick and Easy Setup

Installing the eufy Video Doorbell E340 is straightforward for both wired and battery-powered configurations.
