call home to listen to outdoor mic?

[clemslay@xxxxxxxxx]

I would like to be able to call home, enter some code,
and be able to listen to a outdoor mic.
(rioting nearby in street, no point coming home
until it ends) (no law, don't bother going there)

A camera or two might be nice, maybe later,
but a mic kept dry would be the most important.
I didn't want to use an answering machine,
so that rules out the room monitor with external
mic.

Any ideas?  Anyone make a "box" for this?

Thanks.
