• Power Source: Wired (requires an existing doorbell wiring setup).
• Cloud Storage: 3 months of free cloud storage with an option for more.

Now, let’s get into the pros and cons.

The Pros: Why We’re Impressed

1. Dual Camera Clarity

The most standout feature of the Eufy E340 is its dual-camera setup. The top camera provides the traditional view you’d expect from a video doorbell, but the second camera captures a low-angle shot of your porch area. This is a game-changer for porch piracy—the low-angle camera lets you see packages and even catch thieves in the act with razor-sharp clarity.

In terms of video quality, the 2K resolution is crystal clear. Whether you’re checking in on a delivery or reviewing footage of an incident, you’ll have a much clearer image than you would with standard HD cameras. This dual setup gives you 360-degree coverage of your doorstep.

2. Advanced Motion Detection

Eufy’s person detection technology is a standout feature. It uses AI to distinguish between humans, animals, and other moving objects, reducing the number of false alerts you get. When a person approaches your door, you’ll get an alert, but you won’t be bothered by every car or leaf blowing by. This is a much-needed feature for anyone sick of constant notifications from their video doorbell.

3. Two-Way Audio with Crystal Clear Sound

We tested the two-way audio by having a conversation with a delivery driver, and the sound quality was surprisingly good. The speaker is loud enough for clear communication, and the microphone picks up voices without distortion. Whether you're asking the delivery person to leave a package in a different spot or talking to a visitor, the interaction feels natural and not muffled.

4. Great Cloud Storage and Local Backup Options

Eufy provides 3 months of free cloud storage, which is perfect for storing important footage without paying extra fees. If you prefer, the Eufy E340 also supports local storage via a microSD card, offering another layer of security and peace of mind.

The Cons: What Needs Work

1. Setup Quirks

While the Eufy E340 is generally easy to install, we encountered some minor setup quirks that were frustrating. The doorbell requires an existing wired doorbell system, so if you’re installing it in a home without a wired setup, you’ll need to purchase an additional adapter (which isn’t included). Once we got it hooked up, the connection process via the Eufy Security app was a bit finicky, requiring multiple attempts to sync the device.

In addition, the initial app setup took longer than expected, especially when connecting it to smart home assistants like Google Assistant and Alexa.

2. Wired Only

The Eufy E340 is a wired-only doorbell, which might be a dealbreaker for renters or anyone without an existing doorbell wiring setup. While this ensures continuous power (no need for battery changes), the lack of a battery option limits its flexibility. If you're looking for a more portable solution, this might not be your best choice.

3. Smart Features Could Be Smarter

Although the Eufy Security Video Doorbell has a decent set of features, there are some areas where the smart functionality feels a bit behind. For example, the person detection works well, but it can still be triggered by passing vehicles or other small movements. We also wish there were more customizable motion zones for greater control over what areas trigger alerts. Additionally, while the integration with Google Assistant and Alexa is solid, there could be more in-depth smart features like automation or event-based triggers.

Real Test: Caught a Porch Pirate in the Act!

We decided to really put the Eufy E340 to the test during a porch pirate situation. Sure enough, a few days after installing the doorbell, we had a package stolen from our doorstep. Fortunately, the dual-camera clarity caught everything in great detail.

The footage was clear enough to make out the thief's face, and the motion detection feature helped us pinpoint the exact moment the package was taken. The video quality was sharp enough that even small details, like the thief's shoes and the vehicle they drove off in, were visible. The two-way audio allowed us to speak to a neighbor who witnessed the incident, helping us gather more details.

We were able to download the footage and share it with the police, who were able to act on the information.
