eufy Floodlight Camera E340 Review: Dual Cam, 360° PTZ

The eufy Floodlight Camera E340 is one of the most capable hardwired floodlight cameras available without a subscription. It combines a dual-camera setup (3K wide-angle and 2K telephoto), full 360° pan/tilt with AI subject tracking, 2000 lumens of adjustable floodlight output, and free local storage via microSD or HomeBase. For a driveway, shed, or backyard installation where continuous recording and broad coverage matter, it’s a compelling package. The main caveat is that installation requires a hardwired junction box, and the dual-camera system has some resolution trade-offs in tracking mode worth understanding before buying.

The eufy Floodlight Camera E340 is available on Amazon.

Design and Installation

The E340 has a clean, purposeful design with two large adjustable LED panels flanking a central motorized camera module. The white finish holds up well outdoors against most siding and trim colors. The camera module sits on a motorized pan/tilt assembly that can rotate 360° horizontally and 120° vertically, covering a full property perimeter from a single mount point. Build quality is solid and the IP65 rating means it handles rain, dust, and temperature swings without issue.

Installation requires hardwiring into a standard outdoor junction box, replacing an existing fixture or running new wiring. The process is straightforward for anyone comfortable with basic electrical work and takes 30 to 45 minutes. eufy includes mounting hardware and clear instructions. The camera connects to your network during app setup, which guides you through the process step by step.

Dual Camera System and Video Quality

The dual-camera setup is the E340’s most distinctive feature. The 3K wide-angle lens captures a 130° field of view covering the full scene, while the 2K telephoto lens provides 3x optical zoom for pulling in detail from up to 50 feet away. The two feeds can be viewed simultaneously in split-screen mode within the eufy Security app, or you can switch between them independently. The 8x hybrid zoom combines the optical and digital ranges for impressive reach when identifying a face or license plate at distance.

There is one important resolution caveat worth knowing. When AI tracking mode is active or when using dual-view simultaneously, the maximum resolution drops to 2K rather than the full 3K. This is an architectural limitation of how the dual-camera system processes and streams footage in real time. In practice the difference is not dramatic, but it’s worth knowing that 3K is only available in single-camera mode without tracking active.

Daytime footage is sharp and detailed with accurate color reproduction. Night vision is one of the E340’s stronger areas. When the 2000-lumen floodlights activate on motion detection, the camera captures full-color footage with strong clarity across the illuminated area. Without the floodlights, infrared night vision takes over and delivers a clear black and white image at close to medium range.

360° Pan/Tilt and AI Tracking

The motorized pan/tilt system is smooth and responsive. In AI tracking mode, the camera identifies a detected person, vehicle, or animal and follows them across the frame as they move through the scene. This works reliably at distances up to around 20 feet and handles subjects moving at normal walking pace without losing track. The tracking is especially useful on a driveway or in a backyard where subjects move laterally across the camera’s field.

Auto-patrol mode lets you set up to four preset positions and have the camera rotate through them on a schedule. This is useful for monitoring multiple areas from a single mount point without manual intervention. You can also control pan/tilt manually from the eufy Security app at any time for a full live scan of the surrounding area.

AI detection covers people, vehicles, and animals with free alerts requiring no subscription. Activity zones let you define up to two specific areas of the frame using a precise 6-point shape, which significantly reduces false alerts from movement outside the areas you care about. Motion alerts are fast and consistent in testing.

Floodlight and Siren

The 2000 lumens output is strong enough to illuminate a full driveway or large backyard. Brightness is adjustable in the eufy app, and the lights can be set to motion-activated, always-on during nighttime hours, or ambient lighting mode for continuous low-level illumination. The two panels can be aimed independently to direct light where it’s most needed without being locked to the camera’s direction.

The built-in 95dB siren is triggered manually from the app or automatically on motion detection when the system is configured for active deterrence. Two-way audio lets you speak through the camera to anyone in range, and the speaker is loud enough to be heard across a driveway.

Storage and Subscription

This is one of the E340’s strongest selling points. Local microSD storage up to 128GB enables 24/7 continuous recording with no subscription required. AI detection alerts, activity zones, and all core camera features are completely free. A 128GB card at highest resolution stores up to 144 hours of continuous footage before overwriting from the oldest clips.

For expanded storage, the eufy HomeBase S380 supports up to 16TB via an external drive and connects all compatible eufy devices through a single hub. This is optional but worth considering for multi-camera setups or anyone who wants longer retention.

How It Compares

The E340’s closest direct competitor is the Ring Floodlight Cam Pro. Ring offers 2K HDR video, radar-powered 3D Motion Detection, and Bird’s Eye View, but requires a subscription for any video storage and has no local storage option. The E340’s dual-camera system, free local storage, and 360° coverage give it a meaningful edge for buyers who want to avoid ongoing fees. The Ring ecosystem integration with Alexa is deeper, but for standalone value the E340 wins on paper. For a broader comparison of floodlight cameras see our best floodlight cameras roundup.

The E340’s 360° pan/tilt and dual-camera zoom make it particularly well suited for driveway installations where you need to cover both the near approach and the far end of a long driveway. For mounting tips and placement advice specific to driveways, see our driveway security camera guide.

Frequently Asked Questions

Does the eufy E340 require a subscription?

No. All core features including AI detection, activity zones, and local recording are completely free. A microSD card (up to 128GB) or eufy HomeBase S380 is required to enable continuous recording, but there is no monthly subscription fee.

Does the eufy E340 work without a HomeBase?

Yes. The E340 operates independently with a microSD card for local storage. The eufy HomeBase S380 is optional and adds expanded storage capacity up to 16TB and integration with other eufy devices, but is not required for the camera to function.

Does the eufy E340 support Apple HomeKit?

No. The E340 works with Amazon Alexa and Google Assistant for smart display streaming and voice commands, but does not support Apple HomeKit or Google Home.

Why does resolution drop in tracking mode?

When AI tracking is active or dual-view mode is in use, the E340’s maximum resolution is 2K rather than 3K. This is a processing limitation of running both cameras and the tracking algorithm simultaneously. Single-camera mode without active tracking delivers full 3K resolution.

How bright is 2000 lumens?

2000 lumens is comparable to a standard outdoor floodlight fixture and is bright enough to fully illuminate a driveway or large backyard. The two panels can be independently aimed to spread light across a wider area, and brightness is adjustable in the eufy Security app.
