eufy Floodlight Cam E340 Review: 24/7 Recording, No Subscription

Every no-subscription camera on this site answers the same two questions: where the footage goes, and where the power comes from. Battery and solar cameras avoid wiring but record events only, while plug-in and PoE cameras record more at the cost of a tether. The eufy Floodlight Camera E340 takes a fourth path. It hardwires into a junction box in place of an ordinary outdoor light, which gives it unlimited power for true 24/7 continuous recording, and it saves that footage to a microSD card or an optional HomeBase rather than a paid cloud. On top of that sits the feature no other camera format on this site carries: a 2,000-lumen floodlight that turns the fixture into active deterrence. For a homeowner who wants a wired-in camera that watches everything, all the time, and bills nothing monthly, the E340 is the most complete answer in the floodlight category.

This review reads the Floodlight Cam E340 against eufy's published specifications and the realities of a hardwired installation. The no-fee recording claim gets examined first, then the dual-camera system, the tracking, the light, and the wiring requirement stated plainly.

Two cameras on one mount

The E340's head carries two lenses instead of one. A 3K wide-angle camera holds the broad scene, and a 2K telephoto camera sits beside it, and according to eufy's specifications the two work together to provide 3× optical zoom and up to 8× digital zoom. That pairing matters because optical zoom preserves detail where digital cropping enlarges blur: when the wide camera spots a person at the edge of a driveway, the telephoto can close in for a face-level view instead of stretching a smear of pixels. It is the same dual-camera idea eufy uses on the SoloCam S340, brought here to a wired floodlight body, and it is what separates the E340 from the single-lens 1080p floodlight cameras that dominate the category.

360 degrees of coverage, with AI that follows

The cameras ride a pan-and-tilt head that sweeps 360 degrees horizontally and tilts 120 degrees vertically, so a single fixture can watch a front yard, a driveway, and the path between them with no blind spot behind the mount. On-device AI detection sorts motion into people, vehicles, and pets, subject lock and tracking let the head follow a target as it crosses the property, and an out-of-view detection mode reacts to movement outside the frame the camera is currently watching. For routine coverage, up to four preset positions can be saved and patrolled on a schedule, so the camera cycles through the areas that matter instead of staring at one fixed view. It is the closest thing to a guard slowly sweeping the yard, and per eufy's published details it all runs on the device rather than behind a paid plan.

A 2,000-lumen floodlight that earns its name

Many products called floodlight cameras are cameras with a token LED attached. The E340 is closer to the reverse: two panels output up to 2,000 lumens of dimmable 4,000K light, enough to wash a driveway or a side yard in genuine working light. The illumination can run as motion-activated security lighting or as scheduled ambient light at a chosen brightness, so the fixture does everyday porch-light duty between events. When motion is detected at night, the floodlight snapping on also feeds the camera's color night vision, so nighttime footage keeps the color detail that identifies clothing and vehicles rather than dropping to monochrome. A siren rated up to 100 dB and two-way audio complete the active response: the E340 can light an intruder up, address them, and sound an alarm, not just film them.

One honest hardware note: the light panels are not replaceable. eufy rates them for a lifespan of more than 100,000 hours, which is years of ordinary use, but a buyer should know the LEDs are a fixed part of the unit rather than swappable bulbs.

24/7 recording, no monthly fee

This is the claim that earns the E340 its place on this site, and eufy's specifications back it. With a microSD card up to 128GB in the camera, or a HomeBase S380 connected, the E340 records continuously around the clock — not motion clips, a full timeline that can be scrubbed back to any minute. eufy's own FAQ puts a 128GB card at up to 144 hours, roughly six days, of continuous footage at the highest resolution before the oldest video is overwritten, and a HomeBase S380 expands local storage to as much as 16TB. Viewing, playback, and the AI detection carry no monthly fee, which is the whole point: the saved history that subscription floodlight cameras bill for every month is a line item that simply does not exist here.

One small caveat, disclosed in eufy's own footnotes, is worth repeating. If push notifications with thumbnail previews are enabled, the thumbnail images are temporarily stored in the cloud to deliver them. The video itself stays local; the thumbnail is the exception, and a buyer who wants everything on-device can turn thumbnail previews off.

Installation: hardwired means hardwired

The E340's power is also its price of admission, and it deserves plain language. The camera runs on AC 100 to 240 volts and, per eufy's installation guidance, must be wired into a UL-listed junction box on a wall or under an eave — the same electrical connection an ordinary floodlight uses. There is no battery option and no plug-in adapter; a small 5V/1A input exists for app setup before the unit goes up, but in every power sense that matters this camera is not wireless. For a home that already has a wired floodlight or an exterior junction box, installation is a like-for-like swap: breaker off, three wires across, bracket on. eufy's FAQ advises checking local regulations before installation, and states that outside North America the wiring must be performed by a licensed electrician. A buyer who is not comfortable working on household wiring should plan for an electrician in any case, because this camera cannot go up without real electrical work.

Who should buy it

The E340 is the right camera for a homeowner replacing an existing wired floodlight, or adding one at a junction box, who wants true 24/7 recording without a subscription. It suits wide, wraparound areas — a corner of the house that needs to watch two sides of the property — where the pan-and-tilt head and dual cameras replace what would otherwise take two fixed cameras, and it suits anyone who wants the fixture to deter with light and sound rather than merely record.

Who should skip it

Renters, and anyone whose intended mount has no junction box or exterior wiring, should choose a battery-and-solar camera instead; the E340 cannot go where wiring cannot. Buyers who only want event clips rather than a continuous timeline will find a wire-free camera simpler to place. Apple HomeKit households should note the E340 works with Alexa and Google Assistant but not HomeKit. And anyone who wants weeks of retained footage on the camera alone should plan on adding the HomeBase, since the microSD slot tops out at 128GB.

How it compares

Against the eufy SoloCam S340, the E340 shares the dual 3K-and-2K camera idea and the no-fee storage, but the SoloCam is solar-powered and records events only, while the E340's hardwired power buys true 24/7 recording and a floodlight a battery camera cannot drive — at the cost of the wiring project. Against the eufyCam S3 Pro, the split is resolution versus coverage: the S3 Pro shoots 4K from a battery body that mounts almost anywhere and pairs with a HomeBase for expandable storage, but it records events rather than a continuous timeline, where the E340 watches a wider area all day from its fixed wired mount. And against the Lorex 4K Spotlight, the Lorex is a plug-in spotlight camera that is far easier to power where an outdoor outlet exists, but it looks one fixed direction and offers no panning patrol, no subject tracking, and a spotlight rather than a genuine floodlight. The E340 is the pick when the goal is one wired-in fixture that covers everything, lights the scene, and never stops recording.

Verdict

The eufy Floodlight Camera E340 is the anti-subscription floodlight: a hardwired, dual-camera fixture that records continuously to storage the owner controls and charges nothing monthly for any of it. The 3K and 2K cameras give it real zoom, the pan-and-tilt head and on-device AI give it genuine 360-degree coverage, and the 2,000-lumen light and 100 dB siren make it a deterrent rather than a silent witness. The compromises are inherent to the format — junction-box wiring that some buyers will hand to an electrician, a 128GB microSD ceiling without a HomeBase, non-replaceable light panels, and no HomeKit — and none of them undermines the core promise. For a homeowner with a wired floodlight location and a wide area to watch, it is the strongest no-fee floodlight camera on the site.

Frequently asked questions

Does the eufy Floodlight Cam E340 need a subscription?

No. It records to a microSD card up to 128GB or an optional HomeBase S380, and viewing, playback, and AI detection carry no monthly fee.
