Sound sensor

I need a sound sensor. Something that detects that a sound in a room is higher than a given level (adjustable by potmeter?) and then triggers a DS10 for example.
Is there such a thing available?
The idea is that when my little baby girl starts crying, I can have HomeSeer turn on monitors and show me her camera. That way I can see if we need to go upstairs, or it was a "false alarm".

I solved this in a cheap way, although you must have a server running in your house. With exactly the same purpose : react when the baby is crying, although in my case it's a boy
I use a cheap microphone (like this one :

it may work but risk it may not ..... you may train your baby to clap his hands ...

Oh, I really, really wish I knew more about xPL. But it seems very hard to set up...

I admit that I had a lot of trouble understanding xPL myself. Mainly because it's somewhat cumbersome and not so well documented. A good tutorial would do miracles. As for the hard setup : there is light at the end of the tunnel :

What kind of camera do you have?
There are some models that have a a/d input that you could probably use in conjunction with a electret microphone. Some webcam models have a micrphone built in.

In the end I went for the relay in post 2. Works great!
If I were to use a microphone, either analog or digital I still had to write the trigger software myself. With an analog microphone I would need a spare mic input in the vicinity of the crib. With the digital route I would have to figure out a way of of grabbing the audio stream.
If you have some tips here, I'd love to hear it! I have both analog and digital (wifi) cameras.
