Go to your nearest Electrical Wholesaler and ask about 'Door Intercoms' I
fitted quite a few but they are a pain in the neck if fitted anywhere near a
damp situation. These are ideal for door entry within an Apartment complex
where they are well and truly in the dry of a reception hall.
Said to be 'waterproof', 'weatherproof' etc even to certain grades of water
ingress, but stand by for trouble :-((
Get yourself a peep hole in the door.

I think we should be able to ask who is at the door before opening it, I
remember, and that could be a first for me, remembering that is, there
used
to be gadgets you put outside with a speaker and a microphone in, so if
someone rang the bell you could ask who it was before opening the door,
but
I have no idea where one would go for such a gadget.
So, which store do I ask at first?
