eufy Security E340 2K Dual-Camera Video Doorbell, Model E8214

Dual-Camera E8214: The eufy Security E340 video doorbell pairs a claimed 2K view with two cameras, battery or wired power, and local recording support. It may suit buyers who want coverage toward the doorstep and can supply separate storage, but the listing conflicts on model identifiers and whether a chime is included.

At a glance

Two-camera design is described as front-facing and downward-facing, with the latter aimed at the area near the doorstep.
Listing claims color night vision with a viewing distance of up to 16 feet.
Local recordings require a separately purchased microSD card, with support claimed up to 512GB. The listing also describes HomeBase storage as an option.
Battery operation is offered, while wired mode still requires the battery to be installed.

What to know before buying

A microSD card is not included. The listing says event recording requires a microSD card or a HomeBase.
For wired operation, the listing says the battery must remain installed and power must be connected.

Listing details to confirm

Listing details are inconsistent or unconfirmed: the title calls this E340 and the details give model E8214, while other fields identify T8214. The title says Chime Kit and the built-in-media list names a chime, but the explicit package inventory is empty. Check the selected listing for the exact doorbell and chime contents. The listing calls the video both 2K and 1440 pixels, and describes wired power as 16 to 24V in one place and 16-24V, 30VA elsewhere. Confirm the applicable resolution and transformer requirements before buying.

Who is it for?

A good fit for

Buyers seeking two camera viewpoints, including a downward view of the area directly in front of the door.
Households that prefer local recording and are willing to provide a microSD card or compatible HomeBase.
Installations where battery operation or a wired power arrangement is preferred.

Less suited to

Buyers who require a confirmed chime in the selected package without checking the listing contents.
Buyers who need Apple HomeKit support. The listing explicitly says HomeKit is not supported.
Buyers who expect local recordings to work without separately supplied storage or a HomeBase.

The available aggregate ratings lean positive, with five- and four-star categories represented and no lower-star categories shown. The sample is small and contains no written feedback, so it cannot establish why customers rated the doorbell that way or how it performs. For buyers considering the dual-camera layout and local-storage setup, these ratings do not resolve the listing's package, model, or power-detail uncertainties.

Frequently asked questions

Does this listing confirm that a chime is included?

No. The title and built-in-media field mention a chime, but there is no explicit package inventory. Confirm the contents for the selected listing.

Can it save recordings without a subscription?

The listing claims no monthly subscription for local storage, but recordings require a separately purchased microSD card or a compatible HomeBase.

Can it run on battery or wired power?

Both are claimed. The listing says wired operation still requires the battery to be installed and a connected power source. It gives differing transformer details, so verify requirements before wiring.

Does it work with Apple HomeKit?

No. The listing says it supports Amazon Alexa and Google Assistant but not Apple HomeKit.
