Eufy E340 Wired Security Camera: In-Depth Review

With rising concerns over property safety, having a reliable and intelligent surveillance system can make all the difference. In this review, we’ll dive deep into the Eufy E340 Wired Security Camera’s performance, features, and real-world user feedback to help you decide if this is the right security upgrade for your home or business.

This camera offers a dual-lens system—an unusual and welcome upgrade in this price range. The 3K wide-angle lens captures expansive views, while the 2K telephoto lens zeroes in on faces and license plates. Its AI tracking works with the pan feature to follow intruders and record in greater detail.

The 2,000-lumen floodlight is among the brightest in its class, while the 95dB siren adds an audible deterrent. Compatibility with Wi-Fi 6 ensures seamless connectivity on both 2.4GHz and 5GHz networks.

Performance

Video Quality

Perhaps the most impressive feature of the E340 is its dual-lens clarity. The 3K wide-angle lens captures wide, crisp views with vivid colors in daylight. The 2K telephoto lens complements it with sharp detail that remains consistent even at 50 feet.

At night, infrared and floodlight-enhanced footage make this camera stand out. Even in low light, the image quality is sharp enough to capture facial details, logos on clothing, or numbers on vehicles—rare for outdoor cameras at this price point.

Motion Detection and AI Tracking

Motion detection on the E340 is more refined than in many competitors. The camera distinguishes between humans, vehicles, and pets, reducing false alarms from passing shadows or rustling trees. Once it detects a person, the camera smoothly pans to follow them, recording the entire interaction with a level of precision typically reserved for high-end PTZ (pan-tilt-zoom) cameras.

The auto-patrol feature allows you to schedule panoramic sweeps of your property. This makes it harder for someone to avoid the camera’s field of view, and it adds a layer of active surveillance rather than just passive monitoring.

Lighting and Siren

The 2,000-lumen floodlight provides serious illumination, enough to light up driveways, yards, or side alleys. You can adjust brightness levels based on time of day or motion activity, which conserves energy without sacrificing deterrence.

The built-in 95dB siren is loud enough to startle trespassers and alert neighbors. When combined with motion detection, it can act as an effective intruder deterrent.

Storage and App Integration

You have two options for video storage:

1. microSD Card (up to 128 GB) for local storage
2. HomeBase S380 integration for encrypted video storage and smarter AI (like facial recognition)

The Eufy Security app is responsive, easy to use, and offers real-time alerts, video playback, scheduling, and manual controls. Push notifications are fast, and the camera connects in under two seconds on strong Wi-Fi.

Customer Feedback

Customer reviews from various platforms highlight the real-world strengths and drawbacks of the E340. Here’s a synthesis of what users are saying:

Feedback Category	Summary
Video Quality	“Crystal-clear both day and night”
Motion Tracking	“Very accurate and responsive”
Lighting	“Extremely bright, illuminates the entire yard”
Installation	“Straightforward if you’re replacing an existing floodlight”
App and Connectivity	“Smooth and intuitive app; Wi-Fi 6 makes a big difference”
Build Quality	Mixed; some say “very robust”, others feel it’s “a bit plasticky”
Customer Support	Generally positive; responsive and helpful
Value for Money	“No subscription fees is a huge plus”

One recurring praise is the lack of monthly fees—a significant cost-saving over time. Users also appreciate the quick setup process, especially if replacing an older wired floodlight. The dual-band Wi-Fi receives praise for maintaining a strong connection without dropouts.

However, a few users have reported concerns about plastic construction feeling “less premium” than expected, particularly for a device exposed to weather. Others wanted better HomeKit integration, though the HomeBase S380 adds some smart home features.

Pros and Cons

To summarize the strengths and limitations of the Eufy E340:

Pros

• High-Quality Dual Cameras with hybrid zoom
• Panoramic 360° View with AI tracking
• Powerful 2,000-lumen Floodlight

Final Verdict

The Eufy E340 Wired Security Camera strikes an excellent balance between cutting-edge features, reliability, and long-term value. Its dual-camera system with AI-powered motion tracking, 360° panning, and ultra-bright lighting places it well above most consumer-grade outdoor cameras in terms of capability.
