You can trigger a phone call on the Gigaset. The phone call could trigger action on LinuxMCE.
I hate to be a pest but I just don't understand. What do you mean by trigger a phone call? So someone says something in the room...anything, Or the baby starts crying and that will trigger the Gigaset to place a phone call? What then, I set the phone to call an extension in the house? That extension receiving a phone call triggers the lighting and video alerts I want? Please break it down for me, i'm interested but i'm having a hard time following you.
Maybe you could install a security camera and make a small microphone to infrared LED VU meter?
If you have a cheap VU meter like this: velleman.eu distributor/products/view/?id=352812 (MK146 on google)
and remove all the LEDs, you can take some infrared led and solder it in the required spot. Then place the device in view of the camera and make a camera trigger.
Because the cheap CCD and CMOS cameras are extremely sensitive to infrared light, the LED will turn bright white in the image. This should be able to trigger a movement alarm.
Maybe a camera is a bit more useful in a nursery than a phone and is definitely cheaper than any 'Siemens Gigaset'.
Interesting! This sounds great in theory, also there are VU meters with mics built in for fairly cheap. I'd consider it if someone can confirm that a bright light will trigger a movement alarm. I know the camera in my Droid can see the IR signals from my remotes so in theory I don't see why this wouldn't work. I don't know if it would be bright enough though, plus I haven't used my soldering iron in years. Can someone confirm if lights can trigger an alarm? Especially in the daytime, I think this is where this idea will definitely fail.
There are many projects out there that can create an event from sound, maybe you can work up a dce device, it would also be a start for control by sound. The sound can come from any device, but a well placed microphone like the Solo might be best for baby monitoring.
here is a sample project i found, since i have 2 grand baby's now, i was interested in this also.http://audiotrigger.sourceforge.net/
I LOVE this idea. Unfortunately that software is for windows, I don't suppose WINE is compatible with LMCE? I don't want to have a windows box setup just for this. I'll have more time next week to play with this so i'll search for a Linux alternative. Then I can setup an MD in the nursery, install an app like this and get it married or duct taped to Lmce.
