Little follow up .... firstly I have to thanks @
EMPIRETECANDY, he helped a lot me to solve the issue with the camera, so thanks !
The camera, during the daytime, @4K is ... fantastic , during nighttime, well, isn't a Starlight, but is much, much better than, for example, the hikvision EXIR DS-2CD2T42WD-i8, less noise and more details (to be honest, seems that the SmartIR on the hik works better, but I havent tested in deepth yet).
Now I'm a bit busy, but soon I'll post something about ....
Cheers,
jonatha
