A decent wireless door bell has the same advantage, in that I can take
the receiver bell unit anywhere with me. I often spend time in the
garage/ workshop remote from the house and if I'm expecting an arrival,
I can take the bell along with me.

The sounder for my doorbell plugs into a mains socket, which gets
rid of part of the battery problem.

I can just see Harry wandering around with one of those, mains lead
trailing...

However, because it is not
near the front door, and additionally the sound is produced when
the push is released, callers almost always knock as well.

I have two underdome bells, one in the downstairs hall, one at the top of
the house. Can be heard everywhere - even when listening to the radio or
whatever, and can also be heard outside the front door. The illuminated
bell push may help too - although you still sometimes get numpties who
knock on the door without trying the bell. If you ask them why, the usual
reply is doorbells often don't work. The plague of cheap wireless types.

Somebody recently remarked that it wasn't working, and I
demonstrated their error, commenting to them that I thought the
point was to put it where _I_ could hear it. The indicator light
flashes, but is clearly not trusted.
