The Eufy Video Doorbell E340 is a strong choice for package visibility and local recording. Its front-facing camera focuses on people, its downward-facing camera covers the floor near the entrance, and its built-in 8GB storage avoids a required subscription.
The E340 Kit also includes an extra 6,500 mAh rechargeable battery. That gives you a choice between battery operation and a suitable wired power setup, but it only supports 2.4G Wi-Fi and does not work with Apple HomeKit.
What does the Eufy Video Doorbell E340 do well?
The Eufy Video Doorbell E340 does best when your main concern is seeing both visitors and deliveries. A single camera aimed at face height can miss a parcel below the frame, while the E340's downward-facing camera is designed to cover that lower area.
The front-facing camera focuses on people, and the downward-facing camera captures the floor in front of the door. That two-camera layout suits entrances where packages are commonly left close to the threshold.
The E340 provides 2K FHD video. More detail can help you inspect a visitor or delivery area, although final clarity still depends on lighting, camera placement, motion and the condition of the lens.
Its built-in 8GB eMMC storage supports local recording without a required subscription. That keeps the storage method simple, but you should still review how long recordings remain available and save important clips when needed.

Eufy Video Doorbell E340 review: key features
The E340 combines dual cameras, 2K FHD video, local storage and rechargeable battery power in one outdoor doorbell. It is a better fit for an entrance-focused camera than for broad yard monitoring.
eufy Security Video Doorbell E340 Kit: Best for package visibility
- Dual cameras
- 2K FHD
- Built-in 8GB storage
- Extra 6,500 mAh rechargeable battery
- Color night vision
A dual-camera doorbell for households that want a people-focused view plus coverage of the floor near the entrance. The kit includes an extra 6,500 mAh rechargeable battery and built-in 8GB storage.
Pros
- Downward camera helps show the floor near the door
- Built-in 8GB local storage
- 2K FHD video
- Works with selected eufy chimes, Alexa and Google Assistant devices
Cons
- Only supports 2.4G Wi-Fi
- Not compatible with Apple HomeKit
- Battery operation needs a charging routine
The extra quick-release rechargeable battery is useful if you want to keep a spare ready while another battery is charging. The kit's product information describes the extra battery as 6,500 mAh, so battery planning should focus on charging access and how often the doorbell records or responds to motion.
The doorbell uses wireless connectivity and supports 2.4G Wi-Fi. Check your network layout before installation, especially if the entrance is far from the router or separated by dense walls.
The E340 can connect with an existing mechanical chime. It can also pair with eufy HomeBase 2, eufy HomeBase 3, eufy Minibase Chime models T8023 and T8024, Alexa devices and Google Voice Assistant devices.
The product information excludes the original eufy Wi-Fi Chime T8020, eufy Chime T8740 and T8742, and Apple HomeKit. Those compatibility details matter more than general smart-home branding, so check your exact chime before installation.

How useful is the E340's downward camera?
The downward camera is the E340's clearest advantage for package visibility. It is aimed at the floor near the door, which is the area a face-level camera may not show well.
A delivery may be placed to one side, below the main camera or close to the threshold. The second view gives you a better chance of seeing that location, but the final result depends on the mounting angle and the area covered by your entrance.
Before mounting, stand outside and mark the likely visitor and package zones. Check that the camera position does not point mainly at a wall, railing or other nearby object.
Keep the lens clean and avoid placing the doorbell where a porch light creates glare. The downward view is most useful when the floor area is visible rather than blocked by steps, planters or a door frame.
A two-camera doorbell is still not the same as a general security camera. Our video doorbell vs security camera comparison explains when an entrance camera is enough and when you may need wider coverage.
Does local recording make the E340 easier to own?
The built-in 8GB storage makes the E340 easier to budget for because local recording does not require a subscription. It also means the doorbell's storage capacity and recording settings deserve attention.
Local storage can suit households that want recorded clips kept inside the device rather than sent to a paid cloud plan. You should still use the app to understand motion recording, clip retention and how important footage is exported.
The absence of a required subscription does not remove every maintenance task. Keep the doorbell connected to the app, check that recordings are being saved and review alerts so you know the system is working as expected.
The E340 also supports two-way talk and quick replies. Those features can help you respond when you are away, but use short, clear messages and avoid sharing personal details with unknown visitors.
Battery or wired power: which E340 setup fits?
Choose the battery setup if you want a simpler installation and have practical access to the rechargeable battery. Choose a wired setup if constant power matters and your entrance has a safe route to a suitable transformer.
The E340 Kit includes the doorbell and an extra 6,500 mAh rechargeable battery pack. Two batteries can make charging easier to schedule because one can be ready while the other is in use, but you still need to monitor battery status.
Battery life can change with activity, settings, wireless conditions and weather. Place the doorbell where you can remove the battery without needing to dismantle nearby trim or move stored items.
For constant power, the product information describes support for a 16–24V, 30VA transformer. The E340's pre-record function is associated with constant power, and an existing chime may need to be bypassed for that setup.
The LIANSUM 24V Transformer C Wire Adapter is stated as compatible with the Eufy E340 and provides 24V / 500mA output through a 315 in / 8 m cable.
The adapter uses corded electric power and 2-pin non-polarity wires. Keep it unplugged during installation, route the cable carefully and follow the doorbell and adapter instructions.
Do not treat a long cable as permission to run wiring through unsafe locations. If the installation involves fixed household wiring or an uncertain circuit, use a qualified electrician.
What should you check before mounting the E340?
Check the entrance view, Wi-Fi signal, chime plan and power method before drilling. The E340 uses screw-in installation, and its dimensions are 5.9 x 2.03 x 1.11 inches.
Measure the mounting surface and confirm that the doorbell will not be hidden by the door swing, trim or a nearby light. Leave enough access to remove the battery if you choose battery operation.
The E340 is an outdoor device, but outdoor placement still exposes it to dirt, glare and changing weather. Use the manufacturer's instructions for the permitted installation conditions and cleaning method.
Check 2.4G Wi-Fi at the planned mounting point. A phone may show a signal where the doorbell still struggles, so confirm the connection in the app after installation.
The Best Video Doorbell Cameras guide can help you compare camera layouts, storage methods and power choices before you commit to a mounting position.
How does the E340 compare with a single-camera doorbell?
The E340 is the better fit when the area below the door matters as much as the visitor's face. A single-camera doorbell may be enough for a simple entrance where packages are placed directly in front of the lens.
The E340's two views create a more entrance-specific picture. The trade-off is that you need to think about both camera angles, keep both lens areas clear and confirm that the downward view covers the place where deliveries usually land.
The 2K FHD resolution adds detail, while color night vision is intended to keep the nighttime view clearer. The product information gives a clear nighttime viewing distance of up to 16 ft (5 m), so lighting and distance still affect what you can identify.
If you are comparing different two-camera designs, our Wyze Duo Cam Pan review covers another dual-camera approach. The Wyze Cam OG Telephoto review is also useful if you are considering a separate camera with a longer-view design instead of a doorbell.
Is the E340 suitable for an office entrance?
The E340 can suit a small office entrance when you need visitor alerts, delivery visibility and local recording. Alexa and Google Voice Assistant support may also fit an office that already uses those devices.
The lack of Apple HomeKit support can be a deciding issue for an Apple-centered setup. The E340 also supports only 2.4G Wi-Fi, so confirm that the office network offers a reliable connection on that band.
For an office, decide who can access the app and how recorded clips will be handled. Keep the camera aimed at the entrance and avoid capturing areas that do not need monitoring.
Our guide to the best video doorbell for office use compares office-focused priorities such as visitor handling, placement and shared access.
Eufy Video Doorbell E340 review: important trade-offs
The E340's strongest advantage is the combination of dual-camera package coverage and built-in local storage. It also gives you battery operation, an extra rechargeable battery and several chime and voice-assistant options.
Its main limitations are equally clear. It only supports 2.4G Wi-Fi, it does not support Apple HomeKit, and battery operation requires a charging routine unless you use a suitable constant-power setup.
The E340's built-in 8GB storage avoids a required subscription, but local storage still needs checking. Make sure alerts arrive, clips save correctly and important recordings are copied when necessary.
The video doorbell V5 batteries guide covers battery questions for another doorbell model, but battery details are model-specific. Do not use advice for a V5 as a substitute for the E340's instructions.
For official compatibility and setup information, consult eufy's support resources before installing or changing the power arrangement.
Final verdict: who should buy the E340?
The Eufy Video Doorbell E340 is a good match for package visibility, dual-camera coverage and local recording. Choose it when you want the lower area near the door shown alongside the visitor view, and when built-in 8GB storage is more appealing than a required cloud subscription.
Choose the E340 Kit if you prefer rechargeable power and want an extra 6,500 mAh battery for charging rotation. Choose the LIANSUM adapter if constant 24V power fits your installation and you can route the cable safely.
Skip the E340 if Apple HomeKit is essential or your network does not provide a reliable 2.4G connection. For the most direct alternative comparison, start with the best Eufy video doorbell guide and match the camera layout to your entrance.

Is the Eufy Video Doorbell E340 good for seeing packages?
The Eufy Video Doorbell E340 is designed for strong package visibility because it uses a front-facing camera for people and a downward-facing camera for the floor near the door.

Can the Eufy E340 use wired power?
The E340 supports constant power when connected to a suitable 16–24V, 30VA transformer, according to the product information. The LIANSUM 24V / 500mA adapter is stated as compatible with Eufy E340, but installation should follow the doorbell instructions and local electrical safety requirements.
Does the Eufy Video Doorbell E340 work with Apple HomeKit?
