Eufy E340 Doorbell Review 2026: Worth Buying?

Your front door sees more traffic than any other part of your home. Delivery drivers drop packages there. Neighbors knock. Strangers ring at odd hours. A cheap doorbell camera shows you a blurry head and nothing else.

The Eufy Security Video Doorbell E340 tries to fix that problem with two cameras instead of one, and it does it without asking for a monthly fee.

I mounted this doorbell on a busy front porch and used it as my only entry camera. I watched it in bright afternoon sun, in heavy rain, and at midnight with zero streetlight. I charged the battery, drained it, and charged it again. I let couriers leave boxes on the mat to see if the bottom camera noticed.

In a Nutshell:

• Two cameras beat one. The top lens shoots 2K at 2048 x 1536 pixels. The bottom lens shoots 1600 x 1200 pixels and watches your doormat. Together they give a true head to toe view, so you see faces and feet in the same clip.
• Zero subscription cost. The doorbell stores video on 8GB of built in memory. That holds roughly a month of clips for an average home. No card fees, no cloud plan, no locked features.
• Night video is genuinely strong. Dual spotlights produce usable color footage close to the door. Infrared mode looks sharper at distance than the color mode does.
• Battery life lands near one to two months. Eufy quotes far longer. Heavy foot traffic and nightly spotlight use cut that figure hard. Hardwiring solves it completely.
• Real weaknesses exist. There is no Apple Home support, no 5GHz WiFi, no radar detection, and motion alerts arrive a few seconds later than Ring or Nest alerts.
• Best fit: owners and renters who hate monthly fees and want detailed package coverage for around $120 to $160.

The E340 sits in the middle of Eufy’s doorbell lineup, and it is the one most people should look at first. Earlier dual camera models such as the S330 needed a HomeBase hub to work. This model does not. Everything runs from the doorbell itself, which drops the entry price by a large amount.

The headline spec is the camera pair. The upper camera handles the classic doorbell view at 2K resolution with HDR. The lower camera points down at your doorstep at 1600 x 1200. Eufy stitches both feeds into one vertical clip, so a single recording shows a visitor’s face and the parcel near their shoes.

Power is flexible. A 6500mAh quick release battery slides into the back for a screw and go install. Existing doorbell wiring also works, and the wires trickle charge the battery while ringing your indoor chime.

Other core features include two way audio, color night vision, facial recognition, human detection, package detection, activity zones, and canned voice replies. Alexa and Google Assistant both work for voice commands and smart display streaming.

The base package does not include an indoor chime. Eufy sells a kit version that bundles one, and that bundle is worth the small extra spend if you plan to run on battery power.

Unboxing Experience: What Arrives at Your Door

The retail box is small, white, and lighter than expected. Nothing inside feels padded out with filler. Eufy keeps the packaging tidy, with the doorbell resting in a molded tray and accessories tucked underneath in a flat card compartment.

Lift the doorbell out and the first surprise is the size. It stands roughly 150mm tall and only 28mm thick, so it looks like a slim black bar rather than a bulky puck. It feels dense in the hand, mostly because the battery already sits inside.

Under the tray you get two mounting plates. One is flat for a standard door frame. The second is an angled wedge, which aims the lens away from a neighbor’s property or a reflective wall. Eufy also supplies a mounting template sticker, a bag of screws and wall anchors, a masonry drill bit, a screwdriver for the security screw, a short USB C charging cable, and wire nuts for hardwired setups.

The little details land well. The drill bit matters because brick porches are common, and most rivals leave it out. The paper template lines up at the right height with printed guidance.

What is missing is any chime in the standard box, and no charging brick is included either. The cable expects a plug you already own. Setup took me under fifteen minutes from cutting the tape to seeing a live feed.

Design and Build Quality

The E340 wears a matte black shell with a glossy strip running down the front face. The top lens sits above a small spotlight. The button occupies the middle and glows with a soft ring when pressed. The lower lens and second spotlight finish the bottom section.

Fingerprints show on the glossy strip. That is the main cosmetic gripe. A quick wipe clears it, but a fully matte finish would have aged better on a porch.

The tall and narrow shape is a practical win. Wide doorbells like the Ring Battery Doorbell Pro struggle on slim uPVC frames. The E340 slides onto narrow trim without overhanging the edge. Only one color option exists, so a white or light frame shows a hard contrast.

Build quality feels solid. Panel gaps are tight and the housing does not flex under pressure. The unit carries an IP65 weather rating, and mine handled two weeks of storms with no fogging or water intrusion.

A security screw at the base locks the doorbell to its plate. Removal needs the supplied tool, which slows a casual thief. Eufy also runs an anti theft replacement policy in most regions.

One design choice frustrates battery users. The USB C port sits on the battery itself, inside the body. Charging means unscrewing and removing the whole doorbell. A removable battery that slides out from the base would have been friendlier.

Installation and Setup Process

Setup starts in the Eufy Security app. You create an account, tap add device, scan the QR code on the back, and connect the doorbell to your network. Only 2.4GHz WiFi works here, so a dual band router sometimes needs a separate 2.4GHz network name to avoid connection failures.

Battery installation is the easy path. Hold the template at roughly 1.2 metres above the ground, mark two holes, drill, push in the anchors, screw the plate on, then click the doorbell into place. Renters can use the adhesive option on smooth frames, though screws hold far better in cold weather.

Hardwired installation takes longer but pays off. Switch off the breaker, remove your old doorbell, connect the two low voltage wires to the terminals on the back, and mount as normal. The transformer needs to supply 8V to 24V AC. The wires keep the battery topped up rather than powering the unit directly, which is why the doorbell keeps running during short outages.

The app then walks through chime settings, motion sensitivity, and firmware updates. The first update took about four minutes on mine.

Positioning matters more than people expect. Mount it too high and the bottom camera loses your doormat. Mount it too low and faces get cut. The angled wedge fixed a bad view angle on my porch in two minutes.

Aqara Smart Doorbell Camera G410 with Chime

Video Quality in Daylight and at Night

Daytime footage is the E340’s strongest card. The 2K top camera captures clean detail with accurate exposure, even on a south facing door where backlight usually ruins a shot. I could read a delivery label held up at the door and identify a face from around six metres away.

Colors run slightly flat. Greens and yellows darken a little compared with the actual scene. This never affected identification, but the picture looks less punchy than footage from Eufy’s 3K floodlight cameras.

The bottom camera does its job without pretending to be sharp. It shows shoes, parcels, pets, and porch clutter clearly enough. Where the two views overlap, approaching visitors get comically long legs. It looks odd for a second and then stops mattering.

Night performance splits into two modes. Color night vision fires both spotlights and produces genuinely useful color video near the door. Detail fades at the back of the frame, so a car on the street becomes a shape rather than a readable plate.

Infrared mode surprised me. The black and white footage reads sharper at distance than the color mode does. Eufy quotes a 16 foot night range, and usable images stretched a little past that.

My recommendation is simple. Use color mode if your porch is enclosed. Use infrared if you need to see further down a driveway.

Delivery Guard and Package Detection

Delivery Guard is the reason the second camera exists. The doorbell watches the ground near your door and tells you when a parcel arrives, when one still sits outside at a set hour, and when someone walks too close to it.

Package Guarding plays a recorded warning if a person lingers near a box. It feels slightly theatrical, yet it does make a porch pirate hesitate. Uncollected Package Alert pings at a chosen time, with 8pm as the default, and it saved me from leaving a box out overnight twice.

Detection accuracy depends on parcel size. Large boxes, roughly 10 inches or more on each side, register reliably. Padded envelopes and slim book mailers often slip past. Placement matters too. A courier who drops a box to the side of the mat frequently escapes detection.

Here is my honest take. Treat Delivery Guard as a helpful bonus, not a guarantee. It caught most of my deliveries, missed several small ones, and never produced a false package alert.

The bigger everyday benefit is the view itself. Even without an alert, I could open the app and see exactly what sat on my doorstep. A single camera doorbell forces you to guess.

Motion Alerts and Facial Recognition

Motion detection uses a standard passive infrared sensor rather than the radar found on the pricier S330. Eufy gives you a sensitivity slider, a people only mode, and activity zones drawn with a six point shape for the top camera plus a separate zone for the bottom camera.

Zone control is excellent. I removed the pavement and my neighbor’s driveway from the frame, and pointless alerts dropped to almost zero. Person detection stayed accurate out to about six metres in my testing.

Alert speed is the weak spot. Notifications landed a few seconds behind what a Ring or Nest doorbell delivers. On a battery setup, the camera also needs a moment to wake and start streaming. Someone who rings and immediately turns away sometimes appears only from behind.

Facial recognition runs on the doorbell itself. You train it by tagging faces in recorded clips. After a week it labelled family members correctly day and night. Because there is no hub, the profiles start from scratch even if you already trained other Eufy cameras.

Detection covers motion, people, faces, packages, and package theft. There is no animal detection, no vehicle detection, and no sound detection. Cameras at this price from TP Link and Aqara now include some of those, which makes the gap noticeable in 2026.

Storage and Subscription Free Recording

The E340 records to 8GB of internal memory. In my use that held roughly four weeks of clips with moderate traffic, and older footage rolls off automatically once space runs out. You pay nothing, ever, to keep that working.

That single fact changes the maths against Ring and Nest. Both of those brands hide their best features behind monthly plans, and a single doorbell plan costs a few dollars every month forever. Over three years the difference easily exceeds the price of the E340 itself.

Clips live in the Events tab, filtered by date, device, and event type. Finding a specific incident takes seconds. Downloading a clip to your phone works in two taps, which matters if police or an insurer needs a copy.

The limitation is expansion. The doorbell body offers no user accessible card slot, so 8GB is your ceiling unless you add a HomeBase 3. That hub unlocks far larger local storage, cross camera face profiles, and faster processing, but it adds real cost.

Eufy does sell an optional cloud plan. You do not need it. I ran the whole review period without one and never felt restricted, apart from wishing for a bigger local buffer during a busy holiday week.

Battery Life and Charging Reality

Eufy advertises long battery figures based on light use. Real porches are messier than that. My unit ran about five weeks on a single charge with roughly twenty daily motion events and nightly spotlight recording.

Cold weather makes it worse. Winter temperatures shorten runtime noticeably, and heavy color night vision use drains the pack faster than infrared mode does. Users reporting two to three weeks are usually running high sensitivity on a busy street.

Simple settings changes stretch the life. Switching to people only alerts, trimming activity zones, shortening clip length, and choosing infrared over color night vision all help. A strong WiFi signal helps most of all, because a weak link forces the radio to work harder.

Recharging takes around five hours from empty using a standard USB C charger. The annoyance is access. You unscrew the security screw, lift the doorbell off the plate, plug in the battery, and lose coverage for the whole charge.

Hardwiring is the fix I recommend to anyone with existing doorbell wires. The trickle charge keeps the battery near full, your indoor chime rings normally, and charging days disappear. If you cannot wire it, buy the version bundled with a chime and plan on a top up every month or so.

App Experience and Smart Home Support

The Eufy Security app is clean, fast, and free of advertising. Camera tiles sit on the home screen with quick buttons for live view, events, and settings. Navigation never felt confusing, even with several devices added.

One quirk stands out. The thumbnails on the home screen are still images from the last event rather than live previews, so checking a live feed always needs an extra tap.

Settings depth is impressive for a mid priced doorbell. You control detection type, sensitivity, zones, recording length, night vision mode, spotlight brightness, notification style, and quick voice replies. Two way audio came through clearly in both directions during testing.

Smart home support is where the E340 shows its age. Alexa and Google Assistant work properly, including feed streaming to an Echo Show or Nest Hub and using smart speakers as chimes.

Everything else is absent. There is no Apple Home support, no HomeKit Secure Video, no SmartThings, no IFTTT, and no Matter. Apple households and Home Assistant tinkerers will feel that limitation immediately, and it is the single biggest reason to look at the Aqara G410 instead.

What the Eufy E340 Does Not Do Well

Honest reviews list the failures. Here are mine after extended use.

Alerts arrive late. A few seconds sounds trivial until a courier has already walked away. Radar equipped rivals answer faster and filter better.

Storage cannot grow. Eight gigabytes is fine for most homes, but there is no card slot on the doorbell, so heavy users must buy a HomeBase 3 to expand.

Small package detection misses often. Envelopes and slim boxes frequently go unnoticed, and boxes placed off to the side get ignored.

WiFi support is dated. 2.4GHz only, with no 5GHz option, which hurts on congested networks in apartment blocks.

Ecosystem support is narrow. No Apple Home, no Matter, no IFTTT, no SmartThings.

Battery access is awkward. Removing the entire doorbell to charge feels like a step backward from designs with a slide out pack.

Charging leaves a gap. Your door goes unmonitored for roughly five hours unless you hardwire.

No siren exists. Some competitors include a loud deterrent tone. The E340 relies on voice replies instead.

The chime is an extra. Battery users need either a smart speaker or a separate purchase.

None of these are deal breakers on their own. Together they explain why the E340 is a strong value pick rather than a flawless one.

Pros and Cons

Pros

• Two cameras deliver a genuine head to toe view, so faces and parcels appear in one clip
• Sharp 2K daytime footage with clear facial detail at realistic distances
• Excellent night vision with a choice between color mode and sharper infrared mode
• Completely subscription free recording using 8GB of onboard storage
• Battery or hardwired power, so renters and owners both have an easy path
• Precise six point activity zones that cut false alerts to almost nothing
• On device facial recognition that tags familiar people accurately

• Angled mount, drill bit, and full hardware kit included in the box
• Clean, advertisement free app with fast event filtering and easy clip downloads

Cons

• Motion alerts arrive slower than Ring and Nest equivalents
• No Apple Home, Matter, SmartThings, or IFTTT support
• 2.4GHz WiFi only, which struggles on crowded networks
• Storage cannot be expanded without buying a HomeBase 3
• Small packages and off centre parcels often escape detection
• Battery charging requires removing the whole doorbell for around five hours
• No animal, vehicle, or sound detection
• No built in siren
• Indoor chime sold separately on the standard model
• Glossy front strip attracts fingerprints

Price and Value in 2026

The E340 launched at $159.99 and now trades far below that. Street prices commonly sit between $100 and $130, and sale events push it lower. The kit with a chime usually costs a small premium and is the better buy for battery installs.

At that price the value case is strong. A dual camera 2K doorbell with free local recording and facial recognition for around $120 undercuts almost every subscription based rival on total cost of ownership.

Run the three year numbers. A Ring or Nest doorbell plus a basic plan costs meaningfully more over that period, and cancelling the plan strips away features you paid for. The E340 keeps working exactly the same on day one thousand as on day one.

Competition has tightened though. TP Link and Aqara now sell 2K doorbells with free local storage, faster alerts, wider smart home support, and included chimes at similar money. The E340 answers with better overall video quality and the unique second camera.

My verdict on value is clear. Buy it on sale and it is one of the best doorbell bargains available. Pay full retail and the newer rivals deserve a serious look first.

Who Should Buy the Eufy E340?

Buy it if you refuse to pay monthly fees for your own footage. That is the core reason this doorbell exists, and it delivers on the promise without hiding features behind a paywall.

Buy it if package deliveries are your main worry. The bottom camera genuinely shows your doorstep, and no single lens doorbell matches that view.

Buy it if you have an Alexa or Google household and a narrow door frame. The integration works smoothly and the slim body fits where chunky rivals do not.

Skip it if you live inside the Apple ecosystem. No HomeKit support means no Home app tiles and no HomeKit Secure Video, and no firmware update will change that.

Skip it if split second alerts matter to you. A radar based doorbell reacts faster and filters passing traffic better.

Skip it if you need weeks of continuous archive footage without buying a hub.

For everyone else, the E340 remains a smart, honest, well built doorbell that costs nothing to run. After months on my door, it earned its place. Worth buying? Yes, especially at sale pricing.

Frequently Asked Questions

Does the Eufy E340 need a HomeBase or subscription?

No. The doorbell connects straight to WiFi and records to 8GB of internal storage at no cost. A HomeBase 3 is optional and only adds larger storage plus faster shared processing.

How long does the Eufy E340 battery actually last?

Expect roughly four to six weeks in typical use. Busy porches, cold weather, and nightly color night vision can shorten that to two or three weeks. Hardwiring keeps the battery topped up permanently.

Does the Eufy E340 work with Apple HomeKit?

No. Support covers Alexa and Google Assistant only. There is no Apple Home, Matter, SmartThings, or IFTTT integration.

Can I use the Eufy E340 with my existing doorbell chime?

Yes. Wiring the doorbell to an 8V to 24V AC transformer rings a mechanical or digital indoor chime. On battery power you can use an Alexa or Google speaker, or buy Eufy’s plug in chime.

Does the Eufy E340 support 5GHz WiFi?

No. It runs on 2.4GHz networks only. Creating a separate 2.4GHz network name often fixes pairing problems on dual band routers.

Can I expand the storage on the Eufy E340?

Not on the doorbell itself. The 8GB of onboard memory is fixed, and expansion requires connecting the doorbell to a HomeBase 3.

Is the Eufy E340 waterproof?

It carries an IP65 weather rating, which handles rain, snow, and dust. Mine survived heavy storms without water getting inside or fogging the lenses.
