I bought this camera in January 2023, a bit skeptical about whether it would meet its specifications, and it turned out to be much better than my expectations. In fact, after a month and a half of use, I bought a second one, and now I can see my entire garden.
It charges very quickly, even in cloudy weather. Throughout the day, the battery indicator is at 100%, and even if I have it on and open at night (not just stationary in one spot, but rotating it through the app), the lowest I've seen it go is 96%.
The clarity is very good both during the day and at night.
The rotation from left to right, up and down, is very fast and has a wide range.
It is indeed waterproof.
It has motion detection and takes photos directly (if you want) and sends them straight to your phone.
Otherwise, you can access the files and view them whenever you want. Especially if you add an SD card, it can store many photos.
Installing the camera and the app on my phone was very easy and took 5-10 minutes.
It has a fairly powerful speaker for cases when you speak through the app to be heard in the surrounding area (fortunately, you can adjust the volume as much as you want), unlike its slightly weak microphone. So, you don't hear everything clearly from the outside (I'm not talking about loud sounds, of course).
It has a very loud siren and lights in case of emergency.

If I have something negative to say, it's that the app has frozen twice in six months. The first time was for about five minutes (it couldn't see the cameras as if they were offline), and the second time was for about three hours. It fixed itself on its own.

However, after six months, I'm seriously considering buying a third camera.
