excellent camera doorbell. it does everything it promises. to avoid writing too much, I will only say that the essential difference from xiaomi is that it does not disconnect. and. it has immediate response which is the most important feature for this product

Excellent product, easy to install, includes everything needed in the package which from the beginning gives you a sense of quality. The doorbell functions as a Home Base where the camera is paired. Very long signal range, flawless operation. Highly recommended without hesitation!!!

Recognizes movements and records videos. In poor lighting or if there is contrast, however, the video is not of good quality.
Overall, if someone just wants to record movement and be notified if someone is outside the door, it is good.
Beyond that, the rest of the functions either malfunction or the experience is below expectations, someone should go for something more expensive

Owner of the product for about 2 months, on the front door, and I have to say the following:

POSITIVES

+ Very good image, although it's 1080p. The wide-angle lens helps a lot in seeing what's happening better.
+ Great customization through the Eufy app. You can adjust the doorbell sound, quick remote responses, the sensitivity of the detection, how notifications come to you, and much more.
+ Very fast notifications, which is crucial when it comes to your security.
+ Good night mode.
+ You can trigger a short alarm through the provided transmitter, which also has a speaker with moderate sound, to scare someone if you want.

NEGATIVES
- Battery. The settings and activity play a role, but in NO case does the battery last 6-8 months as they claim. For me, it lasts about 20 days, not that it's a big hassle for me to charge it every now and then, but it may bother someone.
- False detection. Many times when "detect all motion" is enabled, it detects the moving air as a notification and sends it to you, I don't know exactly why. In human only mode, it is much more reliable.
- Missed detection. Sometimes someone may pass by and simply not be detected as motion. Fortunately, this happens very few times.
- Price. It is a bit expensive compared to the competition, as it is also somewhat bulky, although sturdy.

Conclusion: I consider it a reliable solution for someone who wants to see what's happening outside their home. It is very important that the notifications come instantly, and you can have live communication with the area. I hope in the future the reliability in this aspect is not lost, and the battery doesn't fail. Recommended as a product!

UPDATE: 24/4/2023
After 1 year + of operation, everything works perfectly, image, sound, battery. Reliable product, with notifications that come on time!

UPDATE: 25/11/2023
After some experimentation with the settings, my battery easily lasts around 40 days, which is more than enough. There are no false detections, and the notifications still come on time! Nice work eufy!
