“overall im not convinced its a worthwhile upgrade coming from the S330”
“These are drop-dead perfect.”
“I just got E340 plus mini chime. Currently working on battery only it seems to be working well. I will need to tweak the view, but I think mains power will be required as the battery is down to 80% after just a few days.”
“First I was annoyed as the image quality issues with my E340 dual camera video doorbell. I was reporting via email kept asking for the same (footage, logs, settings, try this/that) which they had already asked before and I provided them the same thing already. Showed they are not reading previous emails and correspondence. Really frustrating. But then, th”
“Had mine over two years faultless”
“Therefore, it has significant limitations in my experience.”
“I got mine for two years, and has device faulty. Not recommended”
“Everything is just a tick or two behind ring. I didn't want to keep paying for ring, but I get it. I do enjoy having all my recordings local with no subscription.”
“it works perfectly!”
“Ive had my eufy cameras for about 3 years.. it sucks so bad. I need to try another brand”
“The doorbell itself offers a range of features and certainly beats my Blink doorbell in this department, although it is also larger and heavier.”
“I ditched my ring doorbell bell and bought the eufy e-340. So far it’s great.”
“Not really had that many issues with mine except the AI is way off sometimes. And the battery drain issue the last update introduced.”
“As I own one, I agree with you. The Absolute best doorbell on the market”
“I got one,very lagging”
“Replaced my Ring Pro doorbell with Eufy E340 doorbell wired in. Great doorbell, better than Ring in my opinion.”
“eufy was so laggy and the bit rate on eufy was to grainy on movement”
“no issues yet but I do know eufy software is buggy as hell. Raised more than a few issues their way to the point where I feel like I”
“I have an Eufy E340 which works well and seems really responsive. The dual camera is actually really useful.”
“I'm relatively happy with mine other than the battery life is pretty bad. This last charge didn't even last me 3 weeks.”
“Rubbish don't buy”
“Jury is still out on the E340. I have a few more weeks for the return deadline. It does some things I like, some I don”
“Having just moved from rip off Ring to Eufy myself I’m very impressed. We have gone for the E340 and the video quality is miles better than Ring. Im not paying £50 a year out too and Rings customer service after my doorbell Ring doorbell died annoyed the hell out of me.”
“My E340 Doorbell horrible and my S340 outdoor cam just junk when trying to speak to someone. They have no noise isolation when speaking and think that has a lot to do with it.”

“My doorbell is compatible with hb3, but for connection stability purposes don’t have it through my homebase and it exposes to HomeKit with the homebase 🤷🏻♂️. It does work though.”
“I purchased a Eufy E340 Video Doorbell because it claimed it could be hardwired, allowing for pre-roll recorded clips. Unfortunately, I haven’t been able to achieve this yet.”
“My E340 doorbell works fine with it though guess I just got an expensive chime left now! lol”
“The E340 doorbell records only events. It does not support 24/7 recording.”
“Well I ended up buying a Homebase 3. After adding that to the mix the doorbell now just shows the percentage and not the plug icon. I have a ticket open with Eufy and also found this thread https://community.security.eufy.com/t/eufy-e340-video-doorbell-hard-wired-issues/3969948/22 Seems like a known thing”
“With the Eufy app I get full resolution and the ability to see the different dual cams. Access to the local storage on the Homerbase. The different modes (Home/Away/Off) are easily accessible to make things different like notifications and such. With homekit I get none of that. Just the (reduced quality) video stream and notifications.”
“I really wanted to have it installed today so I said: "Screw it, I'm going to hardwire it with the battery installed and to my amazement, the app was treating the device differently. The green battery icon turned into a green power plug icon. It looks like the videos are getting 3s pre-roll in them since people appearing at the edge of the camera's frame are”
“I've had mine installed for about 1 week. It's very cold where I live, it's been -22C every night, so that would mean that it charges slower. My battery percentage after a week is 86%.”
