I bought it for 55 euros and I can say that I was pleasantly surprised.
The package includes a USB cable, a charger (5 volts, 2 amps, 10 watts), screws with plugs, a mount to hang it on the ceiling, and a booklet with basic instructions.
I also bought a 64GB SD card (at least class 10 is required). You hold the camera and slowly rotate it upwards, and there is a slot where you insert the card. The application recognizes it and you can format it. Of course, you can also subscribe (3 euros/month for one camera or 10 euros for up to 10 cameras) through the application to have Cloud Storage.
The application allows you to connect multiple cameras and give each one a name so that you can choose what you want to see each time, for example, Living Room, Bedroom 1, Bedroom 2.
In addition to a microphone, the camera also has a speaker, which means that through the application, you can speak into your phone and be heard by the person in the room with the camera.
It detects not only motion but also distinguishes between pets and people. You can give it a command to follow wherever it goes (tracking).
You can also set a specific area, such as the couch in the living room, so that if your pet approaches, you can use a recorded voice message through the application to tell it, for example, "Jack, get down, GET OUT OF THERE!"
Although I intentionally don't have a baby, I stood behind the camera (so as not to be recognized) and played a baby crying sound from YouTube (crying detection). I immediately received a notification on my phone and it started recording.
When you connect through your phone, it also displays virtual arrows that you can move up, down, left, and right to adjust the camera's position. But it's easier to use the "360" button. As soon as you press it, the camera rotates completely so that you can see the entire room directly.
It has some preset profiles for when you are at home, when you leave home, or you can create your own.
When you set the profile that you have left home (Home away), the alarm is also activated. I set it to indicate that I had left home, walked slowly and quietly in the dark, and it detected me and the siren started sounding. It's not very loud, but it creates a noise, and at the same time, I received a notification on my phone that a person was detected in the room.
Of course, it also has night vision. As soon as I turned off the lights, it automatically activated. And the resolution is very good (one photo with the lights on, one with them off). As soon as I turned it on, it returned to normal recording.
Also, you can zoom in on the camera by using two fingers, just like zooming in on a smartphone for images.
In short, the camera and a good 64GB memory card will cost you around 70 euros, and you will be very satisfied with the many capabilities it offers.
