This eufy doorbells on a whole different level compared to my previous system (from a very popular brand that shall remain unnamed, iykyk). This one is way more intuitive, easier to manage, and just feels smarter overall. Super easy for a non-tech savvy gal like me. First of all the video quality? Perf. The nighttime looks like daytime. I was not expecting it to be that clear without blasting a spotlight everywhere, but here we are. Bonus points that I can toggle on and off basically EVERYTHING woth these cameras, something my old system severely lacked on. It’s crisp and you can actually see what’s going on instead of grainy blobs. The motion detection is also much better. I’m not getting spammed every time my windchimes moves, which is such a relief. No monthly fees is the straight up cherry on top, i got SO sick of paying monthly fees on... the other brand. Local storage, expandable options, easy app control it just works. Setup was smooth, everything feels premium, and I finally feel like my home security is actually secure instead of hoping for the best. Couldn’t be happier with my experience as a whole. There is a tiny lag when opening an event but its so miniscule it does not bother me, plus it is recording the whole time so no capturing worries. It is fully compatible with my other eufy system pieces so it feels like a seamless add on.

I bought the eufy E340 doorbell a few months ago for a new house. It mounted very easily, the angle works great. I did have to drill, but there are kits you can get that use stick-on tape. I bought some extra angled shims in case I needed to get a better angle, but I didn't need them. My install is wireless since the old doorbell was also wireless, there isn't a power wire. I'm using the Amazon Echo Show as the chime, it works great; if you don't have the Echo set to fairly loud and/or in a spot where you can hear it, this might not work for you. However, it was super easy- once the doorbell was connected in the Eufy app on my phone, the Alexa app automatically saw it. Then you could just set it in the app to use the Echo Show as the chime. So: ==== VIDEO- the video from both cameras is SUPER clear, especially compared to many other security/doorbell cameras. Let me say, even though it isn't perfect, the night video is FAR FAR better than most other cameras I've tried. At night it has a fairly short range of clear vision, no more than 10 feet or so. Beyond that you can see that there's a person, but the face isn't clear. Still- much better than most cameras. ==== ALERTS- these have been great. By default, it alerts if there is a person in range, and if a package has been either delivered or picked up- it can tell the difference. The alert timing isn't perfect, several times the person would be on the front steps before the alert arrived. But it hasn't been a problem, most of the time as I'm leaving the house, when I step off the porch the alert goes off on my phone. ==== 2-WAY TALK: this has worked great. The person outside can hear me, and they are clear enough for me to hear them. ==== WIFI: I have both 2.4 and 5ghz, the doorbell connected to the 2.4 without issue and hasn't dropped off once. The router is downstairs one floor but there has been no problem with the Wifi. ==== APP: this has also been great. It can access the video live, or play saved clips, there's an Events tab showing when something was detected. ==== BATTERY: This is the one area that I think could be improved on. It does have a pretty large battery in it, but I can't get more than 2 months battery life. They claim 4 months in the user guide, but even with very little use (I check it once a day if I haven't had any alerts) it has not lasted very long. They do sell extra batteries so you can easily swap in a new one, but the hassle of taking the doorbell down & replacing it is just a pain. However, everything else about this doorbell makes it worth it, so a little pain once every 2 months is not a bad tradeoff. ==== MOTION SENSING: Works great, better than almost all other cameras I've tried (which is a lot). I've had one time (in 3 months) where it alerted and saved video, but I couldn't see anything moving. It was at night, so I'm chalking that up to a moth or similar. Other than that, it has not failed to detect a person coming up to the porch- day or night, and it also can tell when they drop off or pick up a package. The motion detection is so good you can really rely on it. You can set the area to restrict motion detection, so dog walkers, moving bushes, animals or trees won't trigger it. ==== CONCLUSION: This isn't the cheapest video doorbell, but for what you get I think it's worth the price. Since I set it up I have not had to do anything with it, it has stayed connected to Wifi, it has stored all the video, the alerts have worked great, the motion detection is superior, app is great, the sound is great, etc etc. So far this is the best one I've found. You really don't have to worry about it except for the battery. Yes, I would buy it again.

Easy enough to install and replace a previous hardwired doorbell. The 15 degree mounting bracket add-on came in very handy, not only to make sure I had the right view for the front door, but also provide a little extra storage space for the wire caps for the extension cables. Definitely use the positioning tape/guide to make it easy to see where the mounting brackets and screws need to be. Battery took 3-5 hours to fully charge before installing and using. Sound quality is spot on, and easy to customize and is compatible with Homebase 3 and Eufy app for alerts; some older doorbell chimes may not work alongside this though, and Homebase alert sounds are limited. Would be nice to be able to customize your own alert sound. You do need to adjust the detection settings as it was picking up every little motion and cars all the way on the street. Lots of features in the app, mostly AI-based to alert you of when a package is delivered, if someone messes with a delivery after, and whether a delivery was forgotten after a certain time you can set. Concerns: I've read there are concerns with the battery charge while hardwired, but it appears the battery will deplete until <90% then start charging back up. Mine has hovered between 88-90% without the chime jumper cables, but I have installed those to see if that changes anything. Transformer already met requirements. At night, there is a slight flicker around the package camera edges, but it's not the actual light causing it; during the day the video is fine. Most likely due to ground/surface surroundings and the infrared light, but isn't affecting the main area of the video feed. Main camera during the day and night is great quality.
