Style: Battery Only,2K
Very nice video doorbell cam. Using it right now for just an indoor cam looking out through a window until I can get it properly mounted to the outdoor wall. I upgraded so it would connect to my Homebase 3 and I like this newest model. Provides a large area of security. Very clear, even through glass window. Clear sound too. Great features, especially now that it's hooked up to the latest Homebase. Has many more options once connected to Homebase 3. Connected with the homebase and internet quickly and was ready to use in minutes. I like that it can hold a micro SD card for storage or be connected to the home base for more FREE storage. Very happy with this purchase.

This is a great doorbell cam. My favorite feature is that it charges and still has a battery. And the storage is local and built in. Its tamper resistant design works great. Only slightly problem is that we get notifications in summer during sunset that it is overheating, but so far it’s working great and is always around 90% charged. It seems like it is always running on AC and just topping off the battery but I could be wrong. The battery can also help in older houses with lower power input as supplemental power.

I had already purchased the eufy Security S330 eufyCam 3 2-Cam Kit with Homebase 3 and decided to add the Eufy Doorbell cam as well. Honestly, there's not a whole lot of detectable difference between the 2K doorbell camera and the 4K S330 camera's on my IPhone. All-in-all, the video quality in both 2 and 4K is excellent. I have not mounted the S330 camera's as of yet, they're just sitting inside the house in different locations until I figure out where they go. Since they're solar rechargeable, the way my house is situated makes that a bit more challenging than I figured. Anyway, this is about the doorbell camera. As I stated, the picture quality is excellent so 5 stars on that. Where I subtract a star, and maybe a second one going forward, is the fact that, although my doorbell camera is wired, the battery is discharging. I've had it installed for about 7 days now and I've gone down from 100% to 87% even though there hasn't been that many detection events. The battery icon alternates from continuously charging to a plug icon so I know it's wired. Plus, the mechanical doorbell is working when the doorbell button is pushed. I'm waiting to see if some kind of power management kicks in and it charges back up. The second issue for the deduction is that I was getting an error intermittently when trying to view a detection notification sent to my phone. I got an error that the video had been manually deleted or was corrupt although I had not done anything other than try to respond to the notification. Not really what you're hoping for if a baddie is on your doorstep. After it happened the first time, I removed the device and added it back. That deserves its own paragraph. I have also gotten notifications where there is no accompanying video. In the screenshot I posted, it shows one notification with the number 1 on the bottom right but when I clicked on that, there was no accompanying video of the event. This was right after a delivery. Ok, a couple design features that suck IMO. When I got an error about corrupted video, I removed the device from HomeBase and added it back. That required that I sync the device by pressing a button on the camera. So, where is the button? On the very back of the camera which means I had to unmount the camera to access the back of it. Oh, by the way, even though it's wired, it continues to lose charge. It will be interesting to see if the wired connection sustains it once the battery is depleted. I guess time will tell. If it does not work when the battery is depleted, I'll have to unmount it again to recharge the battery. Why? The charging port is also not readily accessible because it's on the back of the camera as well. The method for unmounting it is straightforward but I actually bent the key to pop it out because it was so difficult to pop the bottom out. That's kind of a good thing, I guess, unless you have to do it often. Bottom line, it would be nice if the those were accessible without having to unmount the camera. Despite these complaints, the doorbell camera integrated flawlessly with HomeBase 3 and set-up with the app is a breeze for all of their products I purchased. I added a 1TB drive to the HomeBase and I'm confident, assuming I don't have a recurring issue with events that are reported as deleted or corrupted, I'll be capturing whatever security events may arise in real-time.....for free apart from the purchase price. For now, I'm very happy with my purchase. I'll update again when I see what happens with the battery or if the event corruption becomes a recurring issue. Update: I added a third pic showing that the doorbell now indicates it's on continuous power denoted by the plug icon replacing the charging icon. After a couple of weeks I still give it 4 stars out of 5 because it's dropped from the wifi even though it's not more than 10 feet from the router. When that happened the eufy help message said to check the router to see if the device was connected but, there's no friendly name for the device on the router. It would be nice if the app, when looking at device details for each camera, would show the device's mac address so you can distinguish it in your router's device list. Yesterday, it did not notify or record a UPS delivery but it did record me picking up the package although no notification was sent. I have gotten them 99% of the time though and the wifi issue corrected itself. Still happy with the purchase and solid on the 4 stars.

I "liked" my ring, been a customer for probably 6 years. Rates kept going up. Added a 2nd one, switched to the higher tier thinking I would get video recordings on both.. nope! I get video recording on one, live access to the other.. For $100/year. Kept putting off finding alternatives, then my first gen ring battery started to croak. Took it inside to charge all night, wouldn't get past 35% charge. Looked on youtube, swapping out the battery looked pretty easy and straight forward so ordered a battery for $18 to keep it going. Took it apart, my device was not a plug that could be disconnected, it was a HARD wired surface mount connector with potting. Tried to pull it off, and of course that yanked it right off the board. That was the last straw.. Typed into chatgpt, ring like doorbell device with no subscription. Eufy came up a bunch of times. Really wish I had switched sooner. Everything records to an SD card inside that you can access from the app, there are no screws to remove the device (just a small hole in the top to unsnap it). The video quality is amazing, it connects to alexa so you don't need a chime inside the house. Super easy to install and setup. I even 3d printed a plate so I could sneak a usb-cable behind it so I can connect it to a solar panel later. I'm so happy with it, I'm going to be replacing my other ring on my garage soon.
