I live on the fourth floor and the reception from my (audio only unidirectional) baby monitor doesn’t reach to the ground floor. So the stalker would need to be in one of the adjacent flats. Not an insurmountable barrier, but one that I feel comfortable with, since all I need protecting is baby babble.
