We have a fully working doorbell. I really can see how you can miss it.
It's about 4'6" off the ground on the lock side of the door - exactly
where you would expect to find it.

Luckily, I work in a front room, facing the street, so I can see people
coming up the path. That way, I know they are there, because for some
reason very few people seem to know what a doorbell is for. I've just had
a guy pathetically tapping the glass which seems to be what they must
teach nowadays.

I must ask the next numpty why they didn't use the doorbell.

Only solution I have found is to use a PIR to trigger an annunciator
(and put up with false positives from birds). My old system failed, but
when I get round to it I have some new kit which I will plumb in to my
multi-bell wireless system.
