Firstly, we wish to know whether puttng us under surveillance is legal as it seems to us to be a breach of our privacy, i.e. our legal rights. If not, then there is no point in asking for it to be removed, or at least masked on our side of the porch.
We do not wish to speak to him until we know what our legal rights are.
Firstly, we wish to know what our legal rights are regarding this surveillance. There is no point in approaching him until this is clear to us. We do want this removed from our private property, or at least have the detector masked on our side of the porch.
We would consider this a clear breach of our privacy and for no reason we can think of.
