For anyone interested in purchasing it, I inform you from the beginning that the application is YCC365 Plus from the Playstore. The camera's app is OK for the money. It follows the classic connection process where you give location permission to the app, create an account, and connect it to your WIFI. Then, when the QR code appears, you bring it close to the camera to hear the sound, press next, and wait for the pairing to complete.
ATTENTION 1) !!! When you put it in the lamp socket, DO NOT tighten it too much, it is completely fake and it broke for me and got stuck inside. So, I unscrewed the screws from the plastic and luckily managed to remove it with a small pair of pliers, but it broke and I ordered another one! Make sure it is properly inserted and keep it in one place without changing it regularly because you will damage it 100%.
ATTENTION 2) !!! The app may not work immediately after the above pairing process. It initially showed that the camera was not working. It takes a little time, go to the camera settings and activate the "Device switch". At least for me, this helped unlock it.
It has night vision with lighting sensors for the night, it has a microphone, it has an alarm tone that is not automatic, meaning you activate it manually (for example, if you see someone in your space and want to warn them that you saw them), it has intelligent tracking that follows the movement in the space (don't expect it to work perfectly, you have to move like a turtle for it to move on its own and only for a short time, not anywhere it goes because it loses the movement), it has image rollover of 180 degrees if for some reason you want to adjust it to capture the image upside down.
As for the negatives: It does not have manual screen quality, which is generally mediocre to poor for many. With a 100 Mbps internet connection, the camera's response is slow, so you should know what to expect... and with the arrows that you use to direct it, the direction change button does not always respond and may require prolonged pressing with very slow and small rotation movement.
However, in conclusion, with mediocre to poor build quality, average image quality, but a decent app that works with a basic set of options for the camera without displaying errors or delays, it is a decent choice for an amateur user who wants to monitor their indoor or outdoor space (of course, it should be waterproof).
Update December 2023: I ordered another one and it came defective with a faulty reset button and flash, so I returned it. Generally, if the flashlight is defective, it will not pair with the QR code no matter what.
