Start with the doorway, not the box count
The Video Doorbell E340 2-Pack is a straightforward proposition: two dual-camera doorbells at a catalog price of $150.00, compared with a $299.99 comparison price. But the right choice depends less on the saving and more on whether you have a second doorway that genuinely needs its own camera.
Each E340 uses a front-facing camera for people and a downward-facing camera for the floor directly in front of the door. That second view is the practical reason to consider this model at all, and it is also the reason a second unit may be more useful than it first appears. If your main entrance already has a peephole, a porch light and a clear sightline, one unit may cover the job. If you regularly use a back or side door, the 2-pack puts the same dual-camera view at both.
What each doorbell in the 2-pack gives you
- Video Doorbell E340 (2-Pack): Two cameras work together: the front-facing camera focuses on people, while the downward-facing camera fills in the gaps with a view of the floor in front of your door. This dual view is the main argument for placing an E340 at a secondary door where packages are often left out of a standard doorbell's sightline.
Video Doorbell E340 (2-Pack) - Video Doorbell E340 (2-Pack): 2K clarity reveals more details, giving clear and detailed visuals of your doorstep and anyone who drops by. If you are comparing one higher-detail camera with two cameras, 2K is the baseline each E340 unit brings to every doorway you cover.
Two doorbells only help if both doors are used
A dual doorbell setup is not automatically better. The second E340 earns its place when it answers a real question: who is at the back door, whether a delivery was left at the side entrance, or whether someone crossed a door you cannot see from the main hallway.
For two doorbell camera placement, think about where each camera's downward view will land. The front-facing camera handles faces and approaching visitors; the downward camera covers the floor in front of the door. A back door with a step, a mat or a narrow landing is a good candidate because that floor view has something useful to show. A door that opens onto a blank wall or a shared corridor may give you less to work with.
If you have only one active entrance, the second unit is better treated as a spare or a future addition than as a reason to buy the 2-pack today. The catalog does not describe a multi-camera recording requirement, so do not assume the two units must be used together.
Power choices that affect where each doorbell can go
- Video Doorbell E340 (2-Pack): Battery mode allows easy installation with the quick-release battery pack, and you can keep a spare for quick swaps and to avoid downtime due to charging. A second doorbell at a back door may not have existing doorbell wiring, so battery mode is the more flexible placement option for that unit.
- Video Doorbell E340 (2-Pack): To use wired mode, the battery must remain installed and a power source should be connected with 8 to 24V and >10VA. If you want wired operation at either door, check that the existing transformer meets this range before planning the install.
- Video Doorbell E340 (2-Pack): Wired mode also runs off the battery, the difference is the battery is kept topped up at all times. This explains why wired mode is not a battery-free setup; the battery stays in the unit either way.
Chime and hub compatibility to check before you buy two
The E340 can connect with your existing mechanical chime, or pair with eufy HomeBase S280, eufy HomeBase S380, eufy Minibase Chime (T8023), Alexa devices, and Google Voice Assistant devices. It is also compatible with HomeBase S380 with firmware version V3.3.2.6 and above.
One exclusion matters for a two-doorbell plan: the E340 is not compatible with the original eufy Wi-Fi Chime (T8020) or eufy Chime (T8740/T8742). If you already own one of those chimes and were counting on it for the second door, confirm your alternative before buying the 2-pack. The supplied information does not describe how two E340 units behave on a single chime circuit, so treat that as a setup question to resolve with the compatible hub or chime you plan to use.
Night viewing and the second doorway
- Video Doorbell E340 (2-Pack): Color Night Vision uses a dual-light system paired with a light capturing and processing algorithm, with less blur than previous iterations of night vision and a clear nighttime viewing distance of up to 16ft (5m). If your second door is darker than the front, this 16 ft (5 m) figure is the practical limit to plan around when deciding whether one camera or two makes sense.
One E340 or the 2-pack: a fit check
- Choose one Video Doorbell E340: You have a single entrance you actually use, or a second door that already has clear coverage from another camera. One unit keeps the setup simple and avoids a second battery to manage.
- Choose the Video Doorbell E340 2-Pack: You have a front and back door in regular use, especially where packages are left on the floor out of a standard doorbell's view. Two units give both doors the same dual-camera treatment, and the catalog price of $150.00 against a $299.99 comparison price makes the pair the better value if you need both.
- Check before either choice: Confirm your chime or hub is on the compatible list, and if you plan wired mode, confirm the 8 to 24V and >10VA power source. These checks apply to one unit or two.
