The Eufy Video Doorbell E340 is a wireless smart doorbell camera designed to give you a clear view of who’s at your door, wherever you are. With 2K-capable resolution, night vision and two-way audio, it’s built to handle everyday home security without much fuss.
Eufy has a strong reputation for no‑nonsense, app‑driven home security, and this model follows that formula. It’s a compact, weatherproof unit that pairs with your phone and the included chime, so you do not need to be near the door to answer it.
Backed by a user rating of 4.2 out of 5 from dozens of reviews, it’s clearly doing a good job for most owners, combining solid image quality with easy wireless installation at a sensible price for a smart doorbell.
The Eufy Video Doorbell E340 suits anyone who wants to add smart security to their front door without paying high-end prices or dealing with professional installation. If you like the idea of seeing and speaking to visitors from your phone, but do not want a complicated system, this is a good fit.
It’s ideal for typical UK houses and flats where you want a clear view of visitors and parcels. The 160‑degree field of view and 2K-capable resolution mean you can see faces and packages clearly, even if people stand to one side of the door.
If you travel a lot, work irregular hours or get regular deliveries, the combination of remote live view, night vision and two-way audio makes it especially useful. You can tell the courier where to leave a parcel or check who’s knocking, even when you are miles away.
Tech‑savvy users will appreciate that it works with both iOS and Android, but it’s also suitable for first‑time smart home buyers who just want a straightforward wireless doorbell with an app and chime that simply works.
The big win here is image quality. The doorbell supports up to 2K Ultra HD (1536p) video, which is sharper than standard 1080p models and makes it easier to recognise faces and details at the door.
Night vision is built in, so you get usable footage around the clock, not just during the day. For many homes, that is crucial for spotting late‑night callers or keeping an eye on the doorstep over winter evenings.
Wireless connectivity and a cordless design make installation more flexible. You are not tied to existing doorbell wiring, and the included wall mount and screws keep setup fairly straightforward.
Two-way audio, with both a built-in microphone and speaker, means you can chat to visitors or couriers through your phone. It’s practical for directing deliveries, reassuring guests you’re on your way, or deterring unwanted callers.
The weatherproof build and slim, unobtrusive black design mean it should cope well on an exposed front door without standing out too much visually.
The manufacturer warranty is only 1 year, which feels a little short for an outdoor security product that is expected to be in use 24/7.
While resolution goes up to 1536p, the core specification is still positioned around 1080p, and there’s no mention of advanced extras such as person detection zones or package detection that some premium rivals offer.
There’s an 8GB drive size referenced, which suggests limited on‑device storage. For households wanting to keep a long history of recordings, you may find you need to manage clips more actively or rely on any additional storage options Eufy offers.
Finally, as with most smart doorbells, it relies entirely on a stable Wi‑Fi connection. If your router is far from the front door or your signal is patchy, you may need to improve your wireless coverage to get the best from it.
Day to day, the Eufy Video Doorbell E340 is designed to stay out of your way until you need it. Once mounted on the wall using the supplied bracket and screws, it becomes a discreet fixture by the front door, ready to ping your phone when someone presses the bell or steps into view.
The wireless, cordless setup keeps the entryway tidy, with just the compact doorbell unit outside and the chime indoors. There’s no need for drilling through walls for data cables, just power and Wi‑Fi.
Interacting with visitors is straightforward: open the app, see the live feed and speak through the two‑way audio. The built‑in microphone and speaker are there to make short doorstep conversations feel natural, whether you are upstairs or out and about.
Because it’s weatherproof and purpose‑built for outdoor use, you can leave it to handle rain and cold without fuss. Night vision support means the experience does not change much after dark – you still get a clear view when the doorbell rings in the evening.
For core performance, the Eufy Video Doorbell E340 delivers crisp video with support for up to 2K Ultra HD (1536p) resolution, alongside 1080p. That extra sharpness helps when you need to identify someone at a glance or check what’s been left on the mat.
The 160‑degree horizontal field of view is generous for a doorbell camera. It captures a wide slice of your doorstep area, which is particularly handy if visitors stand to one side, or if parcels get left off‑centre.
Night vision is a key feature here, letting the camera maintain usable footage in low light. Whether it’s winter afternoons or late‑night knockers, you do not have to rely on porch lighting alone to see what’s going on.
Two-way audio is fully supported with a built‑in microphone and speaker, so you can listen and respond directly through your phone. That makes the doorbell more than just a passive camera; it becomes a communication point for anywhere you are connected.
On the smart side, compatibility with both iOS and Android means most households are covered, and wireless connectivity with Wi‑Fi keeps the setup clean. The weatherproof, wall‑mounted design and cordless operation round things off as a focused, no‑frills feature set that prioritises the essentials of video quality, coverage and simple communication.
At this price, the Eufy Video Doorbell E340 sits in the competitive mid‑range of smart doorbells, offering more than basic budget models without straying into premium territory.
You’re getting sharp 2K‑capable video, a wide field of view, night vision, two‑way audio and a weatherproof, wireless design – all the key features most buyers need for day‑to‑day home security at the front door.
The 4.2 out of 5 user rating suggests owners generally feel they’re getting good value, with a majority of reviewers happy with image quality and convenience. The relatively short 1‑year warranty takes a little of the shine off, but for many homes this will still represent a solid balance between features and cost.
Overall, if you want reliable smart doorbell essentials without paying over the odds for extra bells and whistles, the E340 offers a fair feature set for the money.
The Eufy Video Doorbell E340 is a well‑rounded smart doorbell that focuses on the basics: clear video, dependable night vision, a wide viewing angle and straightforward two‑way audio. It’s easy to live with, looks discreet by the front door and plays nicely with both iOS and Android phones.
Its limitations are mostly in the finer details – a modest 1‑year warranty and a relatively simple feature set compared with the most advanced models on the market. If you’re chasing cutting‑edge smart analytics or extra‑long warranties, you may want to look higher up the range.
For most households, though, this is a sensible, good‑quality choice. If you want to see who’s at the door, chat to visitors and keep an eye on deliveries without making things complicated or expensive, the Eufy Video Doorbell E340 is well worth shortlisting.
