Goodbye Ring, Hello Eufy
Oh, the saga of my doorstep security! It’s a tale that takes us from the clutches of subscription fees to the land of eufy enlightenment. Let me regale you with the story of how I swapped out my Ring doorbell for the majestic eufy Security Video Doorbell E340—and why it’s the best home upgrade decision I’ve ever made. Once upon a time, I was a loyal subject of the Ring kingdom. But as their subscription fees soared like a dragon over the land—42% increase, my fellow villagers!—I knew it was time to seek a new guardian for my realm. Enter the eufy E340, a beacon of hope in the dark night of expensive subscriptions. Why is the eufy E340 the crown jewel of doorbells, you ask? Let’s start with the video quality. If my old Ring was a muddy peasant, then eufy is the crystal-clear prince. Watching my front porch in Full HD is like having a front-row seat at a theatre where the daily drama of deliveries and doorstep visitors unfolds in Oscar-worthy clarity. And the night vision? A revelation! It turns night into day, revealing all the nocturnal critters and late-night pizza deliveries in stunning detail. It’s like being bestowed with the gift of sight by a benevolent wizard. But perhaps the most enchanting feature is the lack of subscription fees. Yes, my friends, the eufy E340 offers all its glory without demanding tribute. Every feature, every notification, every magical moment caught on camera is mine without additional cost. It’s like finding a treasure chest in your backyard that never empties. Installation was a breeze, a fairy tale of simplicity. I half expected woodland creatures to come and assist, so smooth and easy was the process. And the eufy app? A loyal squire at your side, making setup and daily use as easy as waving a wand. Now, let us not forget the two-way audio feature, a feature so crisp and clear that it rivals the town crier. Conversations with visitors are now less “What did you say?” and more “Ah, yes, delightful weather we’re having.” In closing, the eufy Security Video Doorbell E340 has not just replaced my Ring; it has utterly dethroned it. Everything about this doorbell is superior. The increase in Ring’s subscription fee was the push I needed to discover this gem, and oh, what a gem it is. So, to those standing at the crossroads of doorbell dilemmas, wondering which path to take, let me guide you to the eufy E340. It’s not just a step up—it’s an ascension to the throne of doorstep security. Five stars? No, this doorbell deserves a crown.

Sorry Amazon, but WAY BETTER than a RING.. and no subscription!
We had a RING (like most people I guess, after recommendations from others). Bought the kit with video doorbell, internal sounder, spare battery, and internal sounder / extender.. all in all just under £200, but then we discover you have to pay another £50 a year to actually be able to use it properly! Super-stroppy RING customer services when I called up to ask about this too, so not impressed. Anyway, it started off ok and yes it is a novelty having a new video doorbell, but after a few months we were changing the battery almost every 3 weeks (and this was after tuning off a lot of the 'battery draining' notification features). In the winter we were lucky to get 10-14 days out of the battery, and our front door is recessed to not totally exposed to the elements. We put up with it but then came across the Eufy system at a friends house. Very impressed, works a treat, and has a home hub system for storing video and clips etc.. so no 'taking the pi*s' subscription. (FYI they do offer a subscription if you want that as a backup, but it is optional, not required for your system to function, and costs way less than RING). So far batteries are lasting a decent time (maybe 5-6weeks between changes). Ours has a dual camera for both human visitors and a lower viewpoint for parcels.... or delivery drivers that try to crawl up to your door without being seen :-( ?? The lower camera can detect parcels left at your door and let you now.. and will also ping you when the parcel has been taken. Install is straight forward, and literally guides you through it (the devises actually speak to you telling you what to do). There is the usual masking features, sensitivity settings, people / pet / car detections etc.. and an AI face detection feature too but I haven't set that up yet. Notification are good and the hub works a treat. It does take a few seconds to view a video clip when your phone pings, but we found no real difference in time between that the the RING cloud service (when it worked). Seems very well built, the tech works a treat, the home hub is a great idea and can even be extended by adding another drive if needed. The hub can connect / control other Eufy devices such as CCFTV, robot vacuums etc.. Would I recommend over a RING? For sure. Way better.

Pro’s and cons
I am currently on a quest to reduce my subscriptions a lot of which are getting out of hand due to their exorbitant rising costs. It may seem a little strange then that I have laid out even more money to purchase yet another door bell camera when I already own one that on the whole is giving me goid service. The fact remains at its current price the subscription free Eufy will pay for itself in 18 months. This is my main attraction for the purchase. The features included in the purchase price have impressed me and I am now thinking I may extend my quest to include my current wireless CCTV camera package that too has a sting in the tail with its rising subscriptions. The doorbell is easy to install and comes with the necessary fixings and brackets. It is recommended that the doorbell should be positioned at 1.2m for optimum positioning. Mine is slightly higher by choice. A USB A-C charge lead for the battery and a couple of wires to connect to an existing indoor chime, should you have an existing one fitted? Like a lot of electronics these days the doorbell relies heavily on an app for its setup and usage. The battery that’s included had some charge but requires a full charge before use. If that is your sole power supply I would recommend a spare as the charge time is lengthy. Changing the battery is straightforward. A pointed, pin like token is provided and inserted into the top of the bell. This in turn releases it from its backplate. Once installed the installation process I found easy. There were no issues connecting to my Wi-Fi network and in no time I had two, clear split images. Impressive in the daytime, equally impressive at night especially if the built in light is used transforming the image into colour. The app is feature rich with some features only available with an additional base station or with a subscription. The only concern being that without these additions the saved images are on the bell push itself and would be unattainable should the unit be stolen. There is one disappointment I have relating to the E340 and that is not having an indoor chime included I am reliant on my phone if someone comes to the door. A separate chime is available at cost but if I think back to purchasing a conventional doorbell it would be unheard of purchasing a push without a chime included at one time. My younger self would laugh at the idea of such things. As there is an Alexa skill I was expecting to be able to receive a chime through my smart speakers and although this is possible it’s only possible with an additional home base.

Great bit of kit!
I’m the biggest sceptic when it comes to ‘security door bells’! Having a few of the security including ring, most of them have been pretty rubbish. Ring was ok but costly! However, I have to say it Eufy have ticked all the boxes. It works and does what it says on the tin. It’s a great little security camera, angled, picks up and sends alerts to my phone to which I have a conversation if necessary. Excellent picture including night time camera. So far 10/10. Best one ever! I probably would look any further and defo worth the price!

Wanted this to be good to upgrade from Ring, but it promises much but fails to reliably deliver
I wanted this to be great, to get away from the Ring annual subscription, reviews said it was, but it isn’t. The good - it’s a digital doorbell with all the functions your would expect, but also has a separate camera facing the floor to spot left parcels and will alert you about them and keep an eye on them. Plus it stores video locally on the doorbells internal memory so no subscription needed. Swappable battery, though you do need to buy another one as the swappable spare. The bad - there is a problem with this doorbell which seems to be something deep down in its hardware or software, it doesn’t always pick up motion. I’ve had random days when it’s failed to detect any motion at the door, including residents leaving and returning, along with a number of different postal deliveries it them missed throughout the day. This despite it having a setting switched on to inform of motion detection and this being set to specifically alert to humans and set to maximum sensitivity and the doorbell provided a specific activity zone to monitor, I.e. the path in front of the door all as recommended by their customer service team. As it cannot be relied on to do half of its job then it’s not very secure to my mind. They provide a little sticker for you to pop in to your window showing that you are “protected by an EUFY security device”, It should say “you are protected if I feel like working on this occasion!” I also bought a spare battery to swap out the battery, as the built in battery and having to lose my doorbell when placing it on charge, was one of my biggest hates on my old Ring 2nd gen unit. The doorbell was going through a battery in less than a week on any off high quality settings, if lowered to less than maximum performance then it lasts a bit longer, may get a week or so, but in my experience you will spend you life and your electric bill constantly charging and changing the battery. There customer service statesmen it should last about 6 months on recommended settings, it in my experience it doesn’t. The Amazon integration works when it’s feels like it, but the required Alexa EUFY security skill has a rating of just 1.5 stars of 5, with many reviewers moaning that the motion alerts supposed to come l through their Alexa devices not working. I experienced this also, having 5 echo dots around the house and with the app set to announce motion and door bell presses at each device, sometimes a motion if, detected at all by the doorbell, would activate only on the EUFY app but with all Alexa devices remaining silent on the matter, sometimes a motion would activate only a single echo device and other times (less often) motion would announce as intended on the app and all echo devices, but not often enough sadly. I think there is a deeper fault for this device, there seems to be a fault at a core or software level and I wonder why they are not bothering to fix it via a software / firmware upgrade and fix the shocking poorly rated Alexa app integration, seems like they don’t care. I speak from the experience of having thoroughly tested 2 brand new units, as the EUfY customer service team were kind enough to send me a brand new replacement when I first contacted them with concerns over the original device not functioning correctly and burning through batteries. They sent me a brand new unit, which functioned as intended a few days before the same problems affected that new replacement device too. Got to hand it to EUFY, their customer service team were willing to send me yet another (third) replacement, but I think it’s a deeper problem as 2 brand new units have had exactly the same issue, so I would avoid this unit until EUFY sort their act out, as in my opinion this unit is not fit for purpose currently and I am returning now and heading back to the safety of a new Ring device with a swappable battery and will have to suffer Ring’s awful subscription plan, as I tried to get away and switch to EUFY, but sadly EUFY have really let me down with their seemingly flawed E340 doorbell. Great promises and intent, poor execution and delivery. One final note is the “locking” device of this doorbell, it’s rubbish. The doorbell clips in to a plastic holder/mount which is nicely screwed in, all good so far, but the unlocking device to release the doorbell from this screwed in mount is a small hole at the top and EUFY provide you with a long pin to stick in this hole to unlock and remove device or replace the battery. The device can be also unlocked by pressing the end of a paper clip in the hole or a cocktail stick or anything long and thin really. There are suggestions of finding a suitable screw and screwing that in to the hole online, but it makes you wonder why the manufacturer can’t think of that or make their device more secure. If you are not using the additional Homebase device for additional storage, then the video storage is held in the internal memory directly on the doorbell, a doorbell that can be stolen very easily if you can find something to pop in the release catch hole, like the end of a paper clip. Not overly secure to my mind and another big floor.

Excellent eufy Video Door Bell
Super Simple to install and set-up. It took about 10 minutes from opening the box to having this streaming Video to my Mobile and that includes downloading and registration on the eufy App. Great functionality and a variety of set-up customisations that make this a superb option for both a doorbell and video security deterrent. The spit camera view has the capability to set detection zones to ensure you only receive appropriate notifications. Motion detection can also be limited to human or set for all motions including cards & pets. AI extracts clear facial images for personnel identification. Highly recommended as there is NO Cloud account costs and you can also share notifications across other family / friends through the eufy App.

Not worth the upgrade from the S330 Dual Doorbell
Having had the older S330 Dual battery doorbell for a year i decided to buy this new one considering it to be an upgrade because of the LED lights, removable battery & colour nightvision. The 2K resolution 4:3 aspect ratio is the same on both but it's a pity they didn't make it 4k. On the box it says there is a pre-roll recording feature if you hardwire it but at the time of writing this there still needs to be an update to add it (ETA December 2023). The big selling point is the colour night vision which only works when the LEDs are activated either by detecting motion or ringing during the night time. Quite useful if you have no lighting at the entrance of your door. However expect a greater drain on battery life, which for me is about one month using the Optimal Surveillance setting. It will be less during the winter as lithium batteries are affected by colder temperatures. Whereas i can get two months charge with the S330 during summer & a month during winter. I have a security light at my front door anyway so the LEDs are not essential where i can get colour nightvision on my S330 by turning off the infrared. It's also worth mentioning that unlike on the S330 the LED circle around the ring button doesn't glow when it senses someone approaching, which might make it more difficult to see where to press the doorbell. The removal battery with a usb-c connection allows you to swap them out while charging to keep the doorbell in use. However there are no batteries available to buy yet so i don't know how much they will cost. (Edit) £29.99. Since i am not using the battery doorbell by itself i cannot comment on how it performs without the Homebase. I have it connected to the Homebase 3 which handles the AI for facial recognition & added an SSD hardrive. So have no use for the 8gb memory built into the doorbell (not expandable / removable). Having footage stored on the in built memory will mean you will lose that footage should the doorbell be stolen. You will also not be able to access the events if the Homebase or Doorbell loses its internet connection as the app will go offline. It requires a connection to Eufy servers (probably located in China) for it to operate, however the doorbell still records the footage & the bell will ring. I found the motion detection is better at identifying pets than the S330. The point at which it detects motion is about the same. It can vary according to light conditions & how bright the clothing. The distance of its detection isnt consistent. It can vary between 2 metres to 6 metres on a maximum 7 setting. Unlike on the S330 there is no radar detection on the E340 where you can choose the sensitivity for each angle. You can create two activity zones for both the main camera & bottom package camera but there is no red ignore zone on the E340, so i presume the AI filters them out. Also the Delivery Guard kept sending me false notifications, especially during windy weather where the camera faces a bush & a couple of plant pots. So i found it next to useless & turned it off. Eufy does not include a chime that you can plug in which you will need if you don't have an indoor chime or Homebase, but you can connect it to the Amazon Echo / Show but the footage will not automatically appear when the doorbell is pressed, you have to ask Alexa to show the live feed first which may come with a delay, however it isnt compatible with Google Hubs as far as I know. I use a 3D printed 45 degree wedge made via a third party seller on Ebay as the one included in the box is only 15 degrees. The distance between fixing holes on the backplate are the same, the E340 is just slightly smaller than the S330. The main disappointment i found with the E340 in comparison to the S330 is the poor audio. The background noise reduction Eufy has added is too aggressive & sounds like the mic is underwater. The clarity is far better on the S330. It doesn't pick up any background noise during quiet moments only when sound is loud enough, such as when cars drive past my house which sound like a rocket (see video). It can also cut out when people are speaking especially at a distance greater than 2 metres. I have been in contact with Eufy (see quote below) about the mic issue & despite a firmware update 3.0.7.3 making it quieter the sound is still terrible. They have given me a partial 15% refund as a result. If you have the S330 then i wouldn't recommend this new revision as a worthwhile upgrade unless the LED activated colour nightvision & swappable battery are more useful to you. Anker Support: "We appreciate your patience and understanding in this matter. We have analyzed your new video and observed that the audio pickup of your doorbell is functioning normally at this time. Under normal circumstances, the doorbell has a clear voice pickup distance of 2 meters. Considering the proximity of your house to the road, the latest firmware version has significantly reduced the impact of external noise on voice pickup."

Great video doorbell with no fees!
Great video doorbell. Very clear even at night. One thing to remember though is that you do need a chime to go with it, so had to buy this separately as didn’t realise. Couldn’t get it to connect to my Echo Dot but otherwise it’s all good. Pretty easy to set up. Has internal memory so haven’t bothered with a memory card as just deleting the videos bi-daily when not needed. Presume you can download to another device but not tried this yet.

Dobry dzwonek
Dwie kamery, głośnik, AI, wytrzymała bateria i super wygląd to główne zalety. Dodatkowo braku jakichkolwiek opłat miesięcznych. Wady to niedopracowana AI bo nie zawsze rozpoznaje osoby i wykwywa ruch poza wyznaczonym obszarem co jest irytujące. Aplikacja do obsługi średniej jakości z błędnymi tłumaczeniami i błędami.

Ottimo prodotto e assistenza top!!
Il prodotto è ottimo e bisogna fare attenzione a dove posizionare il doorbell. Dopo essere stato contattato dall'assistenza, sono riuscito a risolvere. Per questo la mia valutazione di questo venditore / azienda è top. Perché non ti lasciano allo sbaraglio anzi. Inoltre è arrivato anche un aggiornamento del firmware che rende più performante il doorbell. Lo puoi posizionare sulla porta se di legno oppure accanto alla porta e fate attenzione all'altezza di posizione, non serve metterlo proprio altezza occhiello porta ma quasi centrale, tipo appena sotto il petto per intenderci, comunque è scritto anche nelle istruzioni come misurarlo, leggetele! Prodotto straconsigliato!

Diese Türklingel ist Referenzklasse!
Ich habe über zwei Jahre eine Kamera von Ring genutzt und war damit eher unzufrieden. Nun habe ich die eufy E340. Genau so sollte eine Kamera sein! Kein sep. Netzteil erforderlich wie bei Ring, ich nutze den vorhanden Klingeltrafo. Vorteil: es klingelt die App aber auch weiterhin der alte Türgong (für alle Mitbewohner, die keine eufy App haben). Die eufy Klingel hat keine Abo-Kosten!! Das Speichermedium ist enthalten. Die eufy Klingel hat eine 2. sep. Kamera für abgelegte Pakete und überwacht ebenfalls (befugte oder unbefugte) Paketentnahme. Auf Wunsch mit Sprachnachricht bei unbefugter Entnahme. Die Kamera nutzt „Local AI“ zur Gesichtserkennung. Man kann zutrittsberechtigte Personen via Foto hinterlegen. Man kann eigene Sprachnachrichten aufnehmen und als „Schnellantwort“ automatisch oder manuell abspielen. Die Kamera der eufy macht auch bei Gegenlicht sehr gute Aufnahmen. An dieser Klingel kann sich Ring eine Scheibe abschneiden. Natürlich ist die Kamera mit Alexa kompatibel und so lässt sich zum Beispiel auf allen Alexa Endgeräten mit Display jederzeit die Haustüre einblenden. Für mich ist eufy u.a. auch auf Grund des Preis-/ Leistungsverhältnises und den gebotenen Features absolute Referenzklasse. Klare Kaufempfehlung. Ich habe zusätzlich noch eine Edelstahblende (Zubehör, nicht im Lieferumfang enthalten) hinter der Klingel installiert, das wertet die Klingel nochmals auf.
