Well, after more testing it seems it may need Neural as you said, I’ll try it as soon as I can in a real environment and also do the proper performance testing to check the kind of hardware we would need.
My idea in this test was detecting a ball hitting some targets set in the wall, so I don’t know if the Plane Detection sample could help, my plan b was using the Custom Detector , but it seems it requieres a bit more of time and learning a technology I’m not familiarised to, so I’ll save tha card on my sleeve at the moment.
There are more depth testing I wanted to do, so maybe I’ll write another post soon with some questions I have if I’m not able to get what I’m looking for 
Thanks a lot for your help @JPlou !
