Choose Floodlight E30 for a straightforward lit area with tracking and continuous recording; choose E340 when the extra camera and closer-view options are useful. Both require a real wired installation. We would settle the mounting point, power and Wi-Fi first, then pay for E340 only when its viewing tools answer a question the simpler arrangement would miss.
What changes beyond the floodlights?
What changes in daily use
| Decision | Floodlight E30 | Floodlight E340 |
|---|---|---|
| Cameras | Number of Camera: Single Camera | Dual 2K / 3K Cameras |
| Headline light output | Lighting Brightness: Up to 2,000 Lumens (2 Panels) | 2,000-Lumen Light |
| Continuous storage route | Floodlight Cam E30 requires a microSD card (up to 128GB) or a connection to HomeBase™ S380 for continuous recording. | Floodlight Cam E340 requires a microSD card (up to 128GB) or connection to HomeBase™ S380 to enable continuous recording |
| Installation | It must be mounted on a wall or under a cornice with a UL-listed junction box. | Floodlight Cam E340 requires hardwired installation with AC 100V - 240V. It must be mounted on a wall or under a cornice with a UL-listed junction box. |
E30 already provides pan-and-tilt tracking for humans and vehicles. E340's notable addition is the dual-camera arrangement and its documented zoom workflow. That is a reason to consider it for a driveway where you regularly want to inspect an area farther from the mounting position.
It is not a measured guarantee of readable faces or plates. Distance, camera angle and lighting determine how useful the scene is. We would buy the extra viewing option for a defined task, not infer a detection winner from resolution alone.
Does a higher model number buy brighter lighting?
The compared pages both list the same headline maximum light output. E340's purchase case therefore should not be built around an assumed increase in brightness. Decide whether its additional camera perspective or network options matter to the installation.
For the lighting itself, plan where the panels will point. The useful goal is to light the area you need without directing glare toward a window or the camera's intended subject. A camera upgrade does not fix an awkwardly placed junction box by itself.
E340 also lists dual-band Wi-Fi. That gives another connection option where the home network supports it, but the practical test is the signal at the finished mounting point. A band name is not a substitute for checking the actual wall, distance and router position.
Do you need a base for continuous recording?
Both official FAQs give a standalone microSD route as well as compatible base storage. If your immediate requirement is a local continuous timeline from a single floodlight, the card arrangement may be enough. Add central storage because you need its capacity or management benefits, rather than assuming it is mandatory for every recording setup.
Card capacity and video settings determine how much history remains. Do not treat a quoted maximum number of days as a permanent archive. Save footage you need to retain, and check a sample recording after installation so an empty card or incorrect mode does not go unnoticed.
Both units also need continuing electrical power for the job. Wi-Fi describes their network connection; it does not make these battery-operated cameras. The mounting and wiring requirements belong in the purchase comparison before the camera is ordered.
What makes this upgrade worthwhile for an owner?
E30 and E340 both call for hardwired installation and a suitable listed junction box. Existing floodlight wiring may make either practical, but an unsuitable location can add installation work that matters more than a difference in hardware price. Use the manufacturer's installation instructions for the exact unit.
Keep a functioning E30 if its recorded view already answers your questions. Consider E340 when you repeatedly want a closer view or its network choice solves an identified connection issue. A complete replacement is a larger expense than the price difference seen by someone buying new.
If Apple Home is essential, do not assume the E340 supports it: the checked FAQ excludes HomeKit. Resolve that platform requirement before choosing either camera on the strength of a feature table. This comparison uses published documentation; tracking speed, night detail and illumination quality were not independently evaluated.
What are the checked package prices?
The checked eufy US standard single floodlight-camera listings are $149.99 for E30 and $219.99 for E340. The listed difference is $70.00. These offers exclude the separately offered AC cable and hub bundles. Pay for E340 when the additional lens and documented functions serve your view, and include any installation work separately. Checkout totals may change with tax, shipping and promotions.
A routine driveway view with suitable wiring
Start with E30 when tracking, a lit scene and local continuous recording cover the task. Spend the remaining budget on correct installation and storage.
Closer inspection is a recurring need
Choose E340 for the documented dual-camera and zoom arrangement. Its value is the extra viewing task, not an assumption that the floodlights themselves are brighter.
Frequently asked questions
Can either floodlight operate from a battery?
These compared models require hardwired power. Their official installation instructions also specify a suitable junction box. Treat the wiring and mounting location as part of the purchase, rather than assuming Wi-Fi means a wire-free installation.
Does E30 need a base to record continuously?
Its FAQ gives a microSD card route as an alternative to a compatible base. That can suit a single-camera setup. Central storage is a separate expansion decision, and its compatibility and capacity still need to match the camera.
Does E340 provide stronger floodlighting?
Both checked pages list the same maximum headline output. E340 is more compelling for its dual-camera viewing tools and connection options. The actual lighting result also depends on how the panels are aimed and where the unit is mounted.
Should an E30 owner upgrade immediately?
Keep it if the current footage and connection serve the driveway. Upgrade when a documented E340 feature solves a recurring problem, such as closer viewing. Replacing a working unit involves the full purchase and installation effort, not just a shelf-price gap.
