    • Excellent dual-camera doorbell with impressive clarity!
Style: Battery/Wired Doorbell + Extra Battery
This eufy E340 kit is an outstanding video doorbell. The dual-camera setup is a game-changer—having one camera for face-level view and a second camera pointing down completely eliminates blind spots and lets you see packages clearly at your doorstep. Highlights: Crisp Image Quality: The 2K FHD resolution delivers sharp, clear video during the day and excellent night vision. Smart & Fast Detection: Motion tracking is fast and accurate, capturing events instantly without missing key moments. Built-in Storage & Removable Battery: Having built-in 8GB storage is great for local recording right out of the box without hidden fees, and the removable battery makes recharging super convenient. If you are looking for a reliable, feature-packed doorbell with great clarity and zero fuss, this one is worth every penny! ... show more

I’ve been very happy with this Eufy Video Doorbell E340 Kit. The video quality is clear day and night, and the dual cameras provide a great view of both visitors and packages.

    • Excellent Security Video Doorbell But Not Alexa Compatible
Style: Battery/Wired Doorbell + Extra Battery
Eufy security cameras, including doorbells, are quite a step up from Ring. All features on Eufy cameras are fully accessible, without any fees and videos are stored locally. No privacy invasion. Storage can be upgraded, can be installed on the device itself or the homebase, videos stored can be shared if desired and are encrypted. The option to store in the cloud and for professional monitoring are available. I keep Eufy running in the background on my phone and notifications are instantaneous. With Ring, if anything was detected, it was gone, before I would get a notification. Only very basic features are available without fees with Ring and one is basically forced into paying for professional monitoring in order to get all the features. With Ring, I didn't install indoor cameras. The Eufy cameras far exceed Ring in features available and clarity/tracking of the camera events. Ring cameras would notify of squirrels, cats and flying plastic bags/leaves. Eufy has options for what one is wanting to detect. I have mine set for vehicles and humans. Not once have I received a notification or alarm for squirrels, cats or flying plastic bags/leaves. I have many of all around here. I am able with Eufy to have the cameras alarm, outside at the unit with sound and lights as well as a very audible alarm inside, when set to alarm mode. It works, as it did alarm one evening with good cause. Didn't have that with Ring nor would I have been confident with Ring only picking up a vehicle or human. Of course, you can manually set off the Eufy alarm also. The Eufy doorbell has not missed one person at the door, a package being dropped off or me picking the package up. With Ring, it was hit and miss with mostly miss. Another Eufy feature I very much like, is the option to tailor alarm modes, Home/Away/Off/Disarmed/Customized, down to each specific device/sensor. I am very impressed and satisfied with all the Eufy products I have purchased. It is advertised as being compatible with Alexa, but I disagree. The problem is not Eufy, but Alexa. I enabled the Eufy Security skill, but the echo devices would not announce Eufy notifications. It was a constant enable/disable/ re-enable/reboot to finally get an announcement. It was short lived and right back to enable/disable, etc. Seems to be a problem for many I noticed as I was troubleshooting on the internet. Very recently I received a notice from Alexa stating it had disabled the Eufy skill and directed me to re-enable. I wasn't able to do that as I would not grant Alexa permission to control my cameras. That's what that cab is all about. If I had a smart light bulb, it wouldn't be an issue. I bought the cameras for the privacy of local storage, and now Alexa wants to control those cameras, which means it has access to them. NO. They were advertised as Alexa compatible so the echo devices should be able to make Eufy announcements without the need for Alexa to have access to the cameras themselves. I don't want the echo devices to show me the view of the cameras, just make the Eufy announcements. It wouldn't even do that before, and now Alexa wants more permissions, to do what?? Alexa has gotten as bad as Ring. Putting those two aside, Eufy is an excellent security system on its own, all the way around. As for Alexa and its skills, no more Alexa compatible devices. ... show more

    • Great plug and play video doorbell. App is somewhat difficult to use.
Style: Battery/Wired Doorbell + Extra Battery
The Eufy E340 video doorbell is a fantastic product. It is completely plug and play out of the box. I turned it on and it worked remarkably well in its default configuration. I have some problems with the UI of the app. It is somewhat non-intuitive. Also, although the battery works wonderfully, I advise new users of this type of product not to judge its performance after initial install. The doorbell is so much fun that the battery's first charge likely will not last the full three months. I expect that subsequent charges will last much longer after the initial novelty has worn off. ... show more

    • if it works its great
Style: Battery/Wired Doorbell + Extra Battery
I think it's great product. I wanted one that had local storage to avoid paying subscription. The sub option is only in case you want to save in the cloud to access remotely. I have some connection issues but I think that's my personal problem because it's my door is a bit far from the router, so I don't think it's fair to give a bad rating because that's my case. I will look for a repeater or relocate the wifi router to cover mñbetter signal to the entrance. Overall I think it's great, it's super great that it comes with two batteries and even cables in case you want to wire. I'm using the batteries and I constantly check the battery % and its very good, it takes on avarsge 5% a day. Basically is not recording at all times, but when it detects movement it saves a clip of 20-30secs (customizable). So depending on the usage it's how fast it depletes. Overall is good and I plan on buying more eufy products for other security purposes -update. changing my review from 5 to 1. This doorbell camera, just stopped working, for no reason, out of nowhere, I did absolutely nothing. It started slowly, I noticed it was not capturing movement, but it was streaming correctly all OK I had a few days where it had "no events", I thought "well maybe there's just not movement at all", then one day randomly it says "offline", I thought someone mightve stolen it, when I brought it inside it was just not being detected by the app, it was offline, though the button of the ring kept working, and it made sounds as if it was still working but it was just not being detected. I tried everything, rebooting, replacing the battery, re-install everything, rebooting to factory setting but no, it stopped detecting my wifi, I couldnt sync to any wifi anymore, so I just returned while I was still within my 30 day purchase, (I had it for 3 weeks max). So, I do believe this thing is an OK product... when it works. But Not sure if I would trust to purchase this again. ... show more

    • Eufy Doorbell “at rest” and “activated,” angle mount; Awful Battery Life
Style: Battery/Wired Doorbell + Extra Battery
Review Image by G
Review Image by G
TL;DR ... this doorbell is power flexible, uses AI effectively, has an attractive build/design, is easy to set up, and uses two good-quality cameras (in day or night). More useful details... Out of the box, this Eufy Doorbell can be installed to use its built-in battery or can be wired directly to your home. Nice. Installation, mounting, and app set up were all straightforward; took about 10 minutes. The hardest part was deciding where, and how high, to place the doorbell! (Eufy does suggest placement but YMMV.) The box came with everything you need, including a template decal that made placing and drilling a breeze; nice touch. The app is a bit clunky (dated?) but works well. Notifications to my phone have been instant. The doorbell itself has a built-in speaker; the doorbell "ding" is very loud and clear. (Another nice feature is that I will hear the doorbell ding in my AirPods if I'm wearing them.) The doorbell has two cameras, so I clearly see both the surrounding area AND the entire floor around my porch. I really like this feature. Visibility at night is good too. Setting detection zones is not intuitive but not hard to figure out. The doorbell can see VERY far in clear sunlight. Before setting up a zone, the camera flagged me at around 45 feet away. AI recognition is eerily accurate (a good thing) ... doorbell can identify animals, people, and packages. It will let you know if someone arrives, puts down a package, or picks up a package. So far, it has not misidentified anything. I haven't set up facial recognition yet; this will let the doorbell know if the person at the door is known/unknown. (Sounds like fun.) Battery: shows 4 out of 5 bars after 2 1/2 weeks of use; unfortunately, there is no percentage. (DO BETTER Eufy.) After 30 days of use (exactly), got a message from the app that the doorbell shut down due to low battery. BATTERY ONLY LAST 30 DAYS! Settings were left at default. :-( Doorbell works with the original Eufy HomeBase and HomeBase 2. The doorbell also works with Alexa and Google Assistant. I haven't use these features so don't know how well they work, or if a hub is required. No HomeKit support at this time (Again, DO BETTER Eufy!) btw ... you can always set up Homebridge or Hoobs to connect this Eufy doorbell to Apple's HomeKit; requires a bit more technical expertise. ... show more

    • High quality with no subscription required
Style: Battery/Wired Doorbell + Extra Battery
Great value and product. The upper and lower view is a great feature. Good sound and the call feature works well. It was very easy to set up. Not having to purchase a subscription is another reason I chose to go with Eufy. I recommend this video door bell system.

    • Happy I got these cameras!
Style: Battery/Wired Doorbell + Extra Battery
I now have three of these around the house after buying just one to try. Do yourself a favor and dont buy those $20 to $40 dollar versions. Been there won't do it again. These are well worth the few extra $. Very simple to set up through the app and work perfectly. Nice clear video night or day. I get about 2 months on a battery and it only takes a minute to change out with the charged spare that comes with this package. AND no subscriptions! Full featured and internal storage for videos without the monthly tariff. I have had the first one for about 3 months and the videos havent started overwriting yet plus you can download anything you want to keep. As good as Ring without the ball and chain subscription if you want to store and retrieve. Highly recommend! ... show more
