The eufy Video Doorbell E340 is our pick for best video doorbellfor one concrete reason: it has a second camera aimed straight down at the step. So it shows the parcel as clearly as the person, it records locally with no plan, and it runs wired or on battery. Everything below follows from those three facts — including the one place the design bites back.

The second camera is the whole argument

A normal doorbell has one lens, mounted at button height and aimed out at face level. It sees a visitor from the chest up and it misses the ground — which means it misses the parcel on the step, the note taped below the handle, and the small dog at the door. The usual workaround is a taller frame that drags the ground into the bottom of a wide-angle shot, where the lens distortion is worst and the pixels are most stretched.

The E340 does something different: a dedicated second camera pointed down at the doorstep, separate from the forward camera on the visitor. The result is a properly framed, properly exposed image of what is on the ground, rather than the smeared corner of a fisheye. If package deliveries are the actual reason you are shopping for a doorbell — and for a lot of people they are — this is the feature that earns its money, and almost nothing else in the category does it with a real second lens. The only listing that matches it is the same doorbell sold as the E340 + HomeBase 3 bundle, which adds a base station in the box.

Wired or battery: the same doorbell, two different products

The E340 will run either way, and the choice changes the doorbell more than people expect.

Wired, into an existing doorbell transformer, it has a constant supply. It can stay awake, it can drive an existing mechanical chime, and there is no cell to recharge. This is the E340 at its best, and it is why it heads our main video doorbell rankingrather than the battery one. A wired install does carry the whole transformer question: a video doorbell draws power continuously, where a mechanical bell drew it for half a second, so the transformer has to meet eufy's published minimum voltage and capacity. An old, small transformer that rang a bell for thirty years can sit below that floor, and the symptom is not a dead doorbell but an intermittent one that reboots mid-call. Check the figure on eufy's support page against what is printed on your transformer before ordering.

On battery, it ignores your wiring entirely, which makes it an option for a rented door or a house with no transformer. But a battery doorbell sleeps until its motion sensor fires, so you lose the continuous standby recording a wired unit can hold, and — the part that catches people — in battery mode there is no circuit to ring an indoor chime. More on that below, because it is the single most important thing to understand before you buy this doorbell to run on a cell. If battery is your plan and an audible indoor bell matters, the bundle with a HomeBase 3 included is usually the better buy; the full field is on the battery doorbell roundup.

What keeps working with no plan, and where the video lives

The E340 records locally with full playback and no subscription. Depending on how you set it up, that is either on-device storage in the doorbell or a paired eufy HomeBase indoors, and either way the footage is yours — there is no monthly fee to keep it, to play it back, or to get alerts. That is the entire commercial difference between this and a cloud-only doorbell, where the recording lives on the manufacturer's server and the bill continues for as long as you own the hardware. The general version of that argument is in local storage vs cloud security cameras, and the doorbells that pass the no-subscription test are indexed at best video doorbells without a subscription.

If you already own a eufy HomeBase, the E340 is the cheaper way into the dual-camera design, because it can record to the base you already have rather than making you buy another one. If you do not own a HomeBase and you want the base station included, that is precisely what the E340 + HomeBase 3 bundle is. The head-to-head between eufy's local-storage approach and Ring's cloud one is at Ring vs eufy, which is the cleanest statement of the two positions in this category.

The chime catch in battery mode

This is the E340's one genuine weakness, and it is worth stating loudly because the product photography does not. A wired doorbell can ring the mechanical bell already in your house. The E340 wired can do that too. But the E340 on batteryhas no chime circuit, and eufy does not put a plug-in chime in the box — so in battery mode an audible indoor bell is not part of the package. You get app notifications and the sound from the doorbell's own speaker, and that is all, unless you add a compatible eufy indoor device to chime through.

For a household of two with phones in hand, that is livable. For a family, for a home office at the back of the house, or for anyone who puts their phone on silent in the evening, it is a real gap — the doorbell rings and nobody hears it. This is exactly the problem the HomeBase 3 bundle solves, because a paired HomeBase is one of the devices eufy lists as a chime for this doorbell, and it is why a battery-first buyer is often better served there. If you want a battery doorbell that simply includes a plug-in chime, the Tapo does, and it records to a microSD card with no plan as well.

Fit and install: what to check before you order

This replaces the existing button, so the practical questions are physical. Measure the flat area on the frame where the doorbell will sit and check for anything that will foul a unit wider than the button it replaces: a storm door that swings across the frame, a narrow mullion, or brick that will need a masonry bit. Two eufy cameras stacked in one body make this doorbell taller than a plain single-lens unit, so the clearance check matters more here than usual.

If you are wiring it, work through the transformer check above — voltage and capacity against eufy's published minimum — and remember that doorbell wiring is a low-voltage Class 2 circuit, so the bell wire itself is not dangerous to handle, but the line-voltage side of the transformer is, and that job belongs to whoever does your electrical work. If you are running it on battery, the first thing to do after mounting is trim the motion zones so the sidewalk and road are excluded; that single adjustment is what decides whether you recharge a couple of times a year or every few weeks. Most doorbells also ship with a small angled wedge in the box — it is not packing material. If the door is set back in a recess or the frame faces slightly away from the path, that wedge is the difference between framing the visitor and framing the wall.

The honest cons

  • Dual-camera video eats more storage. Two streams take more space than one, so plan your HomeBase or on-device capacity accordingly. It is the direct cost of the feature that makes this doorbell worth buying.
  • Battery mode loses the continuous timeline. Like every battery doorbell, it sleeps until motion wakes it, so there is a brief wake-up delay and no rolling pre-roll buffer. If you specifically want a 24/7 timeline, wire it or buy a wired camera.
  • No included indoor chime on battery.Covered above — the single most common reason a battery buyer is happier with the HomeBase 3 bundle.

Who should skip it

Anyone building a eufy system from scratch on battery. If you do not already own a HomeBase and you intend to run this on a cell, the E340 + HomeBase 3 bundle gets you the base and the indoor chime for less than buying the doorbell and a HomeBase 3 separately. Buy the bare E340 when you already have a HomeBase, or when you are wiring it.

Anyone who needs a guaranteed audible bell and will not wire it. In battery mode this doorbell rings a phone, not a hallway. If a bell you can hear upstairs is non-negotiable and wiring is off the table, buy a battery doorbell with a chime in the box.

Anyone chasing the absolute lowest price. The E340 is mid-priced for the category, not the cheapest. If budget is the deciding number and you can accept a single wide lens instead of a dedicated downward camera, the cheaper options are on the battery roundup.

The thing this doorbell cannot tell you

Whether a door or window elsewhere on the house is open. A doorbell watches one approach, the front step, and reports motion in front of a lens — it has nothing to say about the back door, a ground-floor window or the garage side door, and it cannot report that a door was actually opened. A few contact sensors close that gap for a fraction of the price per opening and report a plain binary fact instead of a judgment about pixels. They are ranked at best door and window sensors, and the wider category, wired and battery, sits on the doorbells hub.

What it gets right

  • The downward lens solves the actual problem: a package on the step is invisible to a single forward-facing doorbell
  • Works wired or on battery, so a house with no doorbell transformer is not excluded
  • Records locally with full playback and no plan

What it doesn't

  • Dual-camera video takes more storage than a single stream
  • Battery mode loses continuous standby recording

What it costs to run

Wired to an existing transformer, or rechargeable battery. No subscription for recording or playback.

Skip this if…

you want it to ring an existing mechanical chime and you have no transformer. In battery mode there is no chime circuit — you get app and speaker alerts only, which is a real loss if the household relies on a chime being audible upstairs.

How this review was compiled

Products we claim to have tested: zero. We have not put this doorbell on a door, and we are not going to imply otherwise. What this review is built from is eufy's published product and support documentation, its installation guide, and the general engineering of battery-powered cameras and low-voltage doorbell circuits — every one of which is a source you can open yourself, and they are listed below. Our scoring rubric and the weightings behind it are published in full at methodology, so you can disagree with our conclusion using the same public material we used to reach it.

The alternatives worth comparing

eufy Video Doorbell E340 with HomeBase 3 — if you are buying the system, not the doorbell

The same doorbell, sold with a HomeBase 3 in the box. That base is the difference: it gives you expandable local storage and an audible indoor chime without a separate purchase, which is exactly what the bare E340 lacks in battery mode. It is more expensive than the E340 alone and redundant if you already own a HomeBase, but for a battery-first buyer starting fresh it is usually the better pick, and it is why the bundle, not the bare unit, wins our battery doorbell roundup.

Tapo 2K+ Video Doorbell — if you want no plan and a chime in the box

The most forgiving install here. It runs wired or on battery, includes a plug-in chime, and records to a microSD card with person and package detection free. The compromise is the camera: a single wide lens with a tall field of view shows the doorstep, but with less detail than the E340's dedicated downward camera. If a chime in the box matters more than the best possible view of the step, the Tapo is the more honest recommendation.

Where the E340 sits between them

The HomeBase 3 bundle is the better battery buy because it includes what the bare unit gives up. The Tapo is the easier no-plan install. The bare E340 is the one to buy when you already own a HomeBase, or when you are wiring the doorbell — because wired, it keeps the second downward camera and local recording while adding a real indoor chime through your existing bell, which is the combination that makes it our overall best video doorbell. The rest of the category is indexed on the doorbells hub.

How we picked

Products we claim to have tested: 0

Everyone in this category says they tested a dozen locks on their own front door. We have not tested any, and we say so. Here is what we do instead: read the manufacturer's manual and spec sheet, record the published protocol, power and storage figures, check the published standard where one exists, compute what the device costs to keep running, and cite all of it so you can check the work. Prices come live from Amazon's API and disappear rather than go stale.

Questions

Frequently asked

Does the eufy Video Doorbell E340 work without a subscription?
Yes. It records locally with full playback and no plan — either to on-device storage or to a paired eufy HomeBase — and alerts are free too. There is no monthly fee to keep, play back, or be notified about your footage. That is the whole difference between it and a cloud-only doorbell, and it is the standard we hold hardware to across the subscription-free doorbells.
Can the eufy E340 run on battery, or does it have to be wired?
Either. It runs on a rechargeable battery with no wiring at all, which makes it an option for renters and houses with no transformer, and it also runs wired into an existing doorbell circuit if you have one. Wired is the stronger mode — a constant supply means no recharging and access to an audible chime — but battery is a genuine fallback when wiring is not available.
Will the E340 ring a chime inside the house?
Only if you wire it. Wired into an existing circuit it can drive your mechanical chime. In battery mode there is no chime circuit and no plug-in chime in the box, so you are on app notifications and the doorbell's own speaker unless you add a compatible eufy indoor device. If an audible indoor bell on battery is essential, the E340 + HomeBase 3 bundle includes a HomeBase that chimes, and the Tapo includes a plug-in chime.
What is the difference between the bare E340 and the E340 with HomeBase 3?
It is the same doorbell in both cases — the same dual-camera design with a second lens aimed at the step, wired or on battery. The difference is what is in the box. The bare E340 records to its own on-device storage or to a HomeBase you already own. The bundle ships with a HomeBase 3, which gives you expandable local storage and is one of the devices eufy lists as a chime for this doorbell. Buy the bare unit if you already own a HomeBase or intend to wire it; buy the bundle if you are starting a battery system fresh and want the base and the chime included.
What transformer does the E340 need if I wire it?
Check eufy's published minimum voltage and capacity against the rating printed on your transformer before ordering. A video doorbell draws power continuously rather than in the half-second burst a mechanical bell drew, so a small older transformer that rang a bell for years can sit below the floor, and the symptom is an intermittent doorbell that reboots mid-call rather than a dead one. If you have no transformer at all, run it on battery instead.
Does the second camera really help with packages?
That is the reason to buy this doorbell over a single-lens one. A forward-facing lens sees a visitor from the chest up and misses the ground; a tall-frame doorbell drags the step into the distorted bottom of a wide shot. The E340's dedicated downward camera returns a properly framed, properly exposed view of what is on the step. If deliveries are the main reason you are shopping, it is the feature to pay for.
