eufy Security Video Doorbell Camera E340 Review: dual cameras and no subscription, but not totally perfect

I picked up the eufy Security Video Doorbell Camera E340 mainly because I was tired of paying a monthly fee for my old Ring. I wanted something that could record locally, show me packages clearly, and not nag me for a subscription every time I opened the app. On paper, this E340 checks a lot of boxes: dual cameras, color night vision, 2K video, local storage, and it can run on battery or be wired. That’s basically my checklist in one device.

I’ve been using it for a bit now on a typical suburban house setup: front door with a small step, average Wi‑Fi, and a mix of daytime deliveries and random evening visitors. I swapped it in place of my old doorbell and used the included Chime 2 inside the house. No fancy smart home hub, just the app on my phone and a standard router with both 2.4 and 5 GHz Wi‑Fi.

Right away, the thing that stood out is how focused the product is on being practical rather than flashy. The dual camera setup isn’t just a gimmick; the bottom camera really helps with seeing packages on the ground. Compared to my old single‑lens doorbell, I don’t have to guess if the parcel is actually there or if the courier dropped it slightly off to the side.

It’s not perfect though. Some small things annoyed me: the app could be a bit more intuitive, the battery life depends a lot on how busy your door is, and the 8 GB internal storage is fine but not huge if you get a lot of motion events. Still, for someone who just wants a solid, no‑subscription doorbell that shows who’s there and what’s on the ground, it gets the job done pretty well.

From a value angle, the big selling point is clearly the no monthly fee and the 8 GB built‑in local storage. You don’t have to sign up for any subscription to see recordings, which over a couple of years can save quite a bit compared to Ring or similar services. If you hate ongoing costs for basic features like I do, that alone makes this doorbell worth a serious look. The 8 GB isn’t endless, but for most households it’s enough for a rotation of clips without babysitting it.

On top of that, you’re getting dual cameras, Delivery Guard features, 2K resolution, and color night vision all bundled in. If you compare it to other doorbells with similar specs, especially those with package‑detection features, the E340 comes out looking like good value for money, especially when you factor in the lack of subscription. The included Chime 2 is another plus; you don’t have to buy a separate chime or rely only on your phone for alerts inside the house.

Where the value is a bit less exciting is around the extras. If you need a spare battery for quick swaps, that’s an extra cost. If your transformer isn’t strong enough and you want wired mode, that might be another expense. Also, 8 GB of storage is fine, but if you live in a high‑traffic area, it will overwrite clips faster, and you don’t have the built‑in option to easily expand that storage like with some systems that use microSD or a separate hub.

Overall, though, I’d say the price‑to‑features ratio is pretty solid. You’re paying for a mid‑range device that gives you most of the features of higher‑priced competitors without locking you into a monthly bill. If you just want something that records locally, shows you your packages, and works well day‑to‑day, the E340 offers good value. If you’re chasing the absolute cheapest option or need very advanced smart home integrations, you might find better fits elsewhere.

The design is more about function than style. It’s a tall, rectangular unit with the two lenses stacked vertically and a ring button at the bottom. It’s not something you’ll stare at and admire, but it looks modern enough and doesn’t feel cheap. On my door frame it blends in okay, it’s clearly a tech device, but not over the top. If you’re expecting some fancy designer look, this isn’t that, but it’s fine for a normal house.

The biggest design win is the dual camera layout. The top camera handles the usual face and body view, and the bottom one covers the ground near your door. In real life, that means when a courier drops a package, you actually see it on the ground instead of half‑cut off at the bottom of the frame. On my small front step, it catches everything from small envelopes to bigger boxes without me having to tilt the camera or mount it weirdly.

The button is big and clearly lit, so visitors know where to press. At night, the LED ring is easy to see, and people don’t fumble around looking for it. That sounds minor, but with some other doorbells I’ve seen, the button is tiny or badly lit, and people end up knocking instead. The E340 avoids that. The unit also has a secure mounting bracket with a release pin, so you don’t feel like someone will just yank it off easily, although of course if someone really wants to steal it, any doorbell is at risk.

On the downside, the body is on the chunky side. If you have a very narrow door frame or a tight corner, you’ll want to measure first. Also, there’s only one general color tone, so you don’t really get to match it to your door or trim. But in daily use, the design is practical, clear, and focused on showing you what matters rather than trying to look fancy.

The E340 uses a 6500 mAh rechargeable battery, and the way it’s set up is a bit different from some other brands. Even in wired mode, the battery stays inside and the wired power basically keeps it topped up. So you’re not running it directly off the transformer only; it’s more like a hybrid system. That’s good in the sense that short power cuts don’t kill the doorbell right away.

On pure battery mode, how long it lasts depends heavily on how busy your front door is and how aggressive your motion settings are. With moderate traffic (a few deliveries a week and some family going in and out), and with reasonable motion sensitivity, you’re probably looking at a few weeks to a couple of months between charges. If you crank up sensitivity or have a lot of street movement in frame, it will drain faster. The product suggests you can keep a spare quick‑release battery for fast swaps, which is a good idea if you hate downtime, but that’s an extra purchase.

Charging isn’t hard, but it’s still a bit of a hassle: you either take the whole doorbell off and bring it inside or, if you have it wired, you basically never worry about it because the transformer keeps it charged. For me, wired + battery is the best mix. It means I installed it once and I’m not thinking about it again. Just keep in mind the note: wired mode needs 8–24V and more than 10VA. If your existing doorbell transformer is too weak, you might see weird behavior or slow charging.

Overall, I’d say the battery situation is decent but not magical. It’s not the longest‑lasting thing ever, but it’s fine for a regular household. If your front door is super busy or you live on a main road, expect to recharge more often or plan for wired mode. The hybrid approach makes sense, but it does mean you should check your wiring and transformer before assuming you’ll never touch the battery again.

From a durability point of view, the E340 feels solid enough for everyday use. The housing is rigid, there are no creaky parts when you press the button, and the lens areas are well recessed so you’re not constantly wiping fingerprints off the glass. I installed mine in a spot where it gets some rain and direct sun a few hours a day, and so far there’s no sign of warping or obvious issues. It feels on par with other mid‑to‑high‑range smart doorbells I’ve tried.

The mounting system uses a plate that you screw into the wall or door frame, and the doorbell slides onto it and locks with a small security pin at the bottom. Once it’s locked, it doesn’t wobble or rattle when you press the button, which gives a better feeling of quality. That being said, like most consumer doorbells, it’s not theft‑proof. If someone really wants to rip it off, they probably can, but that’s true for pretty much all of them unless you go for some heavy metal housing.

Weather resistance seems fine so far. It’s designed for outdoor use, and typical rain and dust don’t bother it. I haven’t had it through multiple winters yet, so I can’t say how it holds up to extreme cold or heat long‑term, but based on the build, I’d expect it to handle normal seasons without falling apart. The only thing I’d watch out for is direct, harsh sun all day every day, which can fade plastics over time on any brand.

In short, durability feels adequate for the price and target audience. It doesn’t feel like a toy, but it also doesn’t feel like industrial hardware. For a regular house or apartment entry, I’d be comfortable relying on it. If you’re putting it in a very rough environment or somewhere people might try to tamper with it, you might want extra physical protection, but for normal use it’s fine.

In terms of performance, the 2K video quality is genuinely useful. Faces are clear, you can easily tell who’s at the door, and text on shirts or boxes is usually readable if they’re reasonably close. Compared to my old 1080p Ring, there’s a noticeable step up in detail. The live view loads in a few seconds on 5 GHz Wi‑Fi, maybe a bit slower on 2.4 GHz, but nothing crazy. There’s the usual small delay you get with any Wi‑Fi video doorbell, but it’s within normal limits.

The color night vision is one of the things that stands out. It uses a dual‑light system and some software processing. In practice, that means at night, you don’t just get a grainy black‑and‑white blob; you can actually see colors and clearer shapes up to around the claimed 5 meters (16 ft). For my front path and driveway edge, it’s enough. When someone walks up at night, I can see clothing colors and their face well enough to recognize them, which is what I care about. There is still some noise and blur if they move fast, but it’s better than older night vision I’ve seen.

Motion detection and alerts are fairly reliable. You can tweak the zones and sensitivity in the app so you don’t get pinged every time a car passes in the street. The doorbell focuses mainly on people, which cuts down on false alerts from trees or shadows. The dual camera also helps with the Delivery Guard feature: it can spot when a package is left and when someone approaches it. In practice, it’s not magic, but it did correctly tag most deliveries and let me know when a person walked up near the package later.

On the downside, there are occasional delays or missed events if your Wi‑Fi is weak or congested, so the “Stable Dual‑Band Connection” depends a lot on your router situation. Also, if you have a very busy front area with constant movement, you may need to spend time dialing in the motion settings to avoid too many notifications. But overall, for a normal home, the performance is solid and reliable enough for day‑to‑day security and package watching.

In the box you get the E340 doorbell unit, the Chime 2, mounting hardware, and the usual paperwork. No surprises there. The doorbell itself has the two cameras built in: one facing straight out for people, one looking down for packages. There’s also the 6500 mAh rechargeable battery already part of the design, even if you plan to wire it. The chime is a small plug‑in box that goes into a power outlet and connects over Wi‑Fi/Bluetooth to the doorbell.

Setup is pretty straightforward. You install the eufy Security app, hold the doorbell near your router, and it uses Bluetooth auto‑pairing to find your network. The auto‑discovery actually worked for me on the first try, which is not always the case with smart devices. I had it on my Wi‑Fi and sending notifications within about 10–15 minutes. I tried both 2.4 GHz and 5 GHz on my router; it handled both, and I ended up leaving it on 5 GHz for slightly faster live view loading.

Mounting is simple if you go battery‑only. You just screw the plate into the wall and clip the doorbell on. If you want to use existing doorbell wires, it’s a bit more fiddly, but still doable if you’re comfortable turning off your breaker and handling low‑voltage wires. Important detail: even in wired mode, the battery has to be installed, and your transformer needs to be between 8–24V and more than 10VA. If your house is older, that might mean checking or upgrading the transformer, which is an extra cost some people won’t expect.

Overall, in practice, the presentation and setup are pretty solid. It feels like a consumer product, not a DIY science project. That said, if you’ve never touched a drill or don’t want to deal with wires at all, I’d stick to battery mode. For most people, it’s a 30–45 minute job from opening the box to having it working, assuming your Wi‑Fi isn’t a mess.
