Allow smaller areas for privacy zones

Privacy zones seems like a great idea - automatically redacting my neighbor’s property for their privacy. However the implementation doesn’t work effectively. I have not been able to define black bars protecting my neighbors without also preventing me from seeing who is at the door. We need to be able to define smaller black bars for privacy zones. I need to be able to define bars small enough to cover the windows of houses across the street while usually not blocking seeing who is at the door. Currently the smallest allowed zone blocks near from seeing a huge area right in front of the doorbell so I can not see who is there
