So as was posted by other users before, the privacy zones lacks basic features. 

1- The smaller size is to big

2- The shape is limited to rectangular or square, should have several points to move so we could use hexagonal, octagonal or other geometrical shapes when needed

3- We should be able to rotate the defined privacy zones (it really is necessary)

4- The privacy zone MUST be associated with a defined view point, otherwise when you have several view points (which is my case) that you schedule the camera to rotate to in certain hours, the privacy earlier defined for the former view blocks parts of the image you actually want to see! Its ridiculous in these 360º (or any other automated moving camera) for this to be limited this way, on a fixed one is understandable but on these its just absurd.
