Hello everyone,  
I have already reduced the size of the various alarm areas and activated only human detection, no animals or cars. However, the cam detects my dog and the passage of car. Should I lower the sensitivity? Now in my 3 set areas it is at 90.

I think so, too. E.g. I use 40% for persons and 60% for cars. And by correct settings of the inner and the outer size of each dimension box.

The object detection box for persons seem to be too large. Maybe the initial area. Think about the fact, how large can be a person near to your camera? Guess that for adults and children. The inner box is for the minimal height or dimension for a person, the outer box for the largest.
