eufy Security Video Doorbell E340 Review: Dual cameras and no subscription, but not totally flawless

I’ve been running the eufy Security Video Doorbell E340 on my front door for a few weeks now, swapping it in for an older Ring doorbell. The main reason I bought it was simple: I was tired of paying a monthly fee just to see recorded clips. This one stores video locally and doesn’t lock basic features behind a subscription, which is what pushed me to actually try it.

In day-to-day use, the big difference compared to my old single‑camera doorbell is that dual camera setup. One lens looks straight ahead at whoever is at the door, the other points down at the doorstep to watch parcels. On paper it sounds like a gimmick, but in practice it solves a real problem: I can finally see where the delivery guy actually dropped the parcel without guessing.

I’ve used it mostly on battery power, connected to 2.4 GHz Wi‑Fi, with motion detection and human detection turned on. I also linked it to my phone and an Alexa speaker so I still hear a chime indoors. During this test, it dealt with the usual stuff: grocery deliveries, Amazon parcels, neighbours dropping by, and a couple of late‑night visitors.

Overall, it’s a pretty solid doorbell with a few rough edges. The video quality is good, the night vision is better than what I had before, and the lack of subscription feels like a relief. But the app isn’t perfect, the AI sometimes gets it wrong, and battery life depends heavily on how aggressive your settings are. If you expect perfection out of the box, you’ll be annoyed. If you just want a decent, no‑subscription doorbell with strong features, it does the job.

In terms of value, the E340 sits in an interesting spot. It’s not the cheapest video doorbell on the market, but when you consider what’s included—dual cameras, 2K resolution, colour night vision, AI detection, local storage, and no mandatory subscription—the price starts to look pretty fair. Compared to something like a Ring doorbell, the upfront cost is similar or slightly higher depending on deals, but the difference is that here you’re not signing up for a monthly bill just to keep your recordings and smart alerts.

Where you do need to be realistic is with the extras. There’s no chime in the box, so if you don’t already have a compatible mechanical chime or a HomeBase / Alexa device, you might end up spending a bit more. Also, if you want the most convenient experience, a spare battery is almost a must, which adds to the total cost. So the value is strongest if you already have some of the ecosystem pieces or don’t mind using your phone and smart speakers as chimes.

On the positive side, you’re not paying for cloud storage every month. Over a couple of years, that alone can make this doorbell cheaper than a subscription‑based one, even if the initial price is slightly higher. The features you get—package detection, dual view, flexible motion zones—are usually reserved for pricier or subscription‑locked models. The app isn’t as polished as some competitors, and the AI can be a bit hit‑and‑miss, which does take a bit of shine off the value equation.

So, from a straight “is it worth it?” point of view: yes, for most people who want a capable, no‑subscription doorbell, it’s good value for money. It’s not the bargain of the century, and there are cheaper basic options if you just want a camera and a button. But if you care about parcel visibility and avoiding recurring fees, it hits a nice balance between features and long‑term cost.

Design‑wise, the E340 is taller and a bit bulkier than many basic video doorbells, mostly because it needs to fit two cameras and the battery. The dimensions are around 15 x 5.2 x 2.8 cm, so it’s not tiny, but it doesn’t look ridiculous either. On my door frame it takes up a fair chunk of vertical space, so if you’ve got a very narrow frame or an awkward spot, measure first. The front is a simple black panel: top camera, bottom camera, status LED, and the button with a light ring around it.

The look is pretty neutral: no chrome, no weird curves. It just looks like a modern gadget. I like that it doesn’t scream “expensive security system” from a distance; it blends in enough that visitors notice the button but don’t stare at it. At night, the button ring is bright enough to show where to press without lighting up the whole street. If you hate glowing LEDs, you might find it a bit much, but I’d rather that than people knocking randomly on the door frame.

Installation on the wall is straightforward. The mounting bracket snaps on nicely and feels secure. The included 15° wedge is useful if your door is slightly recessed or if the default angle points at a wall or a hedge. On my setup, I used the wedge to angle it a bit away from the street to avoid constant motion alerts from passing cars. Once it’s clipped into the bracket, it doesn’t wobble, and you need the supplied pin to detach it, which adds a bit of theft resistance. Not bulletproof, but not trivial to yank off either.

Overall, I’d describe the design as practical rather than pretty. It’s not something you’ll admire, but it gets the job done: visible button, clear camera placement, and a form factor that fits most door frames. If you’re obsessed with ultra‑minimal design, you’ll probably think it’s a bit chunky. For everyone else, it’s fine and clearly built around function first.

The E340 uses a 6500 mAh removable battery, and how long it lasts really depends on how many features you turn on and how busy your front door is. In my case, with motion detection on, human detection enabled, colour night vision active, and around 15–20 events a day, the battery dropped roughly a bit over 10% per week. So you’re looking at several weeks between charges in a normal suburban environment. If you live on a busy street with constant motion or crank every setting to max, expect to recharge more often.

Charging is done via USB‑C, which is a relief compared to older micro‑USB stuff. You have two options: either unclip the whole doorbell from the mount and bring it inside, or just remove the battery pack if your setup lets you. A full charge takes a few hours depending on your charger. If downtime bugs you, you can buy a spare quick‑release battery and swap it, which honestly makes life easier than having to rush the charging process.

If you can hardwire it (8–24V, >10VA), I’d recommend it. Even in wired mode, the battery has to stay inside, but the wiring keeps it topped up. That gives you the benefits of a battery backup if the power goes out, plus you don’t have to care about charging cycles. It’s a bit weird at first that “wired mode” still uses the battery, but in practice it works fine and you don’t notice it after setup.

Overall, I’d rate the battery as good but not magic. It’s not one of those devices you charge once every six months unless you barely get any visitors. It’s more realistic to think in terms of weeks, not months, especially if you like all the smart features turned on. For most people that’s acceptable, but if you hate the idea of ever recharging, plan on wiring it in or keeping a spare battery ready.

The E340 is listed as waterproof, and so far it has handled typical UK‑style weather: rain, wind, and some cold mornings. I’ve had it mounted outside without any extra cover, and there have been no leaks, fogging inside the lens, or weird condensation issues. The front glass over the cameras wipes clean easily with a cloth; it doesn’t seem to scratch super easily, but I also haven’t abused it. I’d still avoid scrubbing it with anything rough.

The housing feels solid enough for a plastic‑and‑metal consumer device. It’s not a tank, but it doesn’t feel cheap or hollow either. The mounting bracket locks the doorbell in place with a decent click, and you need the supplied pin to release it. Could someone determined still get it off? Probably, with tools or enough force. But for casual tampering or kids yanking at it, it feels secure enough. After repeated removals for charging and testing, the clip mechanism still feels tight, not loose.

One thing I paid attention to was how it handled temperature changes. On colder nights, I didn’t notice major lag or reboots, and the battery performance dropped a little as expected but nothing dramatic. The Wi‑Fi connection stayed stable, no random disconnects due to weather. The unit is light (about 0.52 pounds), so it doesn’t strain the screws or wall mount over time.

Long‑term durability is always a bit of a question mark with smart devices, especially with software updates and support. The listing says guaranteed software updates until “unknown”, which basically means there’s no clear promise. That’s the part that worries me more than the hardware. Physically, I don’t see obvious weak points for normal home use. So in short: hardware feels reliable enough, weather resistance seems fine, but like any connected gadget, you’re partly relying on the brand not abandoning it too early on the software side.

On the video side, the 2K resolution is genuinely useful. Faces are clear enough to recognise people easily, and you can zoom in a bit on recordings without the image turning into a pixel mess. The dual camera setup works as advertised: the top camera shows the full person and surroundings, the bottom one covers parcels and the doorstep. For deliveries, this is honestly the best part. I can see exactly where a box is, even if it’s tucked against the wall or partly behind a plant pot.

Daytime image quality is sharp, colours are decent, and you can clearly read logos on jackets or parcels at normal door distance. At night, colour night vision kicks in if you have enough ambient light or let the built‑in light system help. Compared to older black‑and‑white IR footage, this is far more usable. Faces are still recognisable, and you can usually spot the colour of clothes or parcels. The trade‑off is that using colour night vision and lights hits the battery harder, so if you’re fully on battery, you might want to tweak those settings.

Motion and AI detection are where things are good but not perfect. Human detection is mostly accurate: it usually ignores cars and trees, but every now and then it will trigger outside the defined zone, just like one of the Amazon reviews mentioned. The activity zone tool is actually quite flexible; you can pull polygon points around to shape the detection area and even mask out sensitive spots like a neighbour’s window. Despite that, the AI still occasionally flags motion just outside the zone, which can be irritating if your door faces a busy street. The package detection works reasonably well: it spots when something is dropped off and when it’s picked up, and you get alerts about it.

The app is usable but not perfect. It’s fairly quick to open live view on a decent Wi‑Fi or 4G connection, and I haven’t had major connection drops. However, some menus are a bit clunky, translations can be off in some languages, and there are occasional minor bugs. Nothing that breaks the product, but you can feel that the software isn’t as polished as the biggest competitors. Overall, performance is strong enough for everyday security, but if you’re picky about flawless AI and a super slick app, you’ll notice the rough edges.

The eufy E340 is a 2K video doorbell with dual cameras: one normal front camera for faces and one downward‑facing camera for parcels and the floor area. It can run either on battery or be hardwired, but even in wired mode the battery has to stay inside, and the wiring just keeps that battery topped up. It connects over 2.4 GHz Wi‑Fi only, no 5 GHz, which is pretty standard but good to know if your router splits bands weirdly.

In the box you get the doorbell unit, a 6500 mAh removable battery pack, a USB‑C cable for charging, the mounting bracket, a 15° wedge, screws, a couple of extension cables, and a pin to detach the unit from the bracket. There’s also a quick start guide and a small warning sticker. No chime is included by default, so you either hook it to your existing mechanical chime or pair it with a compatible eufy HomeBase / Minibase or an Alexa device. That part is slightly annoying if you expected an all‑in‑one kit, but it’s clearly mentioned.

Feature‑wise, the headliners are: 2K resolution, colour night vision, dual‑light system, AI human detection, package detection (Delivery Guard), and local storage without mandatory cloud fees. You can store footage onboard (depending on the exact version or if you link it to a HomeBase with storage). Once the storage is full, it overwrites the oldest clips, so you don’t have to babysit it. Notifications can be tuned to motion, humans only, or just button presses.

In daily use, the E340 feels like a doorbell built for people who want more control and less subscription nonsense. It’s not the slickest ecosystem in the world, and the app has some quirks, but the core idea is clear: you pay once, you get your basic security features, and that’s it. If you’re coming from Ring, the absence of a paywall for recordings and smart detection is honestly the main selling point.
