We are getting a little worried about late night callers, and
I wondered about fitting a communication system, which I'm sure
I've seen, one which enables you to takl to the callers before
opening the door.

I've just had a look in a local DIY store but couldn't see
anything like this, plenty of door chimes which is not exactly
what I'm looking for.

So, where will I find such a gadget?

A web search for things called "Audio Door Entry Systems" should give you
loads to look through.
