Very good choice for replacing the doorbell with a wireless security bell. Completely satisfied with the large area coverage and very good image quality day and night. Good quality and immediate sound performance. The application offers many usage options. The only negative is the delay in notifications in "Delivery Guard" mode.

Positives:
- Image and sound quality
- Battery life
- Range of coverage area

Negatives:
- Occasional delay in notifications

Excellent product, just like all the security and surveillance systems from Eufy, which work perfectly together and are controlled with tremendous ease through an extremely user-friendly and functional ecosystem! Recommended

One of the best purchases I have made, easy installation with options to be placed flat/angled/with battery/power. It works perfectly with the rest of the Eufy system, which is ESSENTIAL to have in order for the device to function, this means it is an add-on unit. The application is really good, I receive notifications immediately when someone appears in front of the door before they reach the doorbell (although I imagine this also has to do with the quality of each person's internet connection). The image quality is very good with great clarity (2K), but where it really impresses is in detection/capture in the dark. The battery really seems to be able to last for months without worrying, and when you see (through the application) that its level has dropped at some point, you recharge it with a very simple process. Finally, it is quite noticeable and elegant, so you don't feel ashamed to have it at your door, quite the opposite.

Excellent product, it can be connected to the analog doorbell wires and charge simultaneously. To operate, it requires the Eufy Home base 2.
