I started making my house smarter by installing a few D-Link DCS-932L in my home.  At first, I installed them to look at my dog whilst working in my office, but when my daughter was born, I moved the camera to point at her cot.

I wanted to get a notification whenever she moved, so I installed Vitamin D (http://www.vitamindinc.com) video on my iMac since it had the best algorithm for discerning people vs other movement (i.e. shadows, light changes).

From Vitamin D, I set up a Rule that would take action whenever there was movement by a person inside a region that I had defined on the screen.

The action taken was that a picture of the movement was sent to IFTTT (http://www.ifttt.com) that subsequently posted the picture to a twitter account.  This allows me to view the twitter account to view any movement remotely.  

VitaminD also makes a REST call "curl -X POST  http://xxxxxxx.xxxx.com:xxxx/vitamind/amelia?announce=off".  This invokes a Java Restlet that is located at vitamind/amelia on my iMac.

The VitaminDAmeliaServer initiates a few actions.  It checks if the light level in Amelia's room is below 0.3, since I don't want to get any notifications if she is just playing around during the day.  It does this by making a call to Amelia Light Level data stream in Sen.se (http://open.sen.se).  This data stream is updated by the USB Weatherboard that is connected to my NinjaBlocks which then updates Open.Sen.se.  (I'll detail how this works some other time)  I only want to be notified if she is restless at night.

I also check that there hasn't been any notifications for the past 3 minutes since I don't want to be bombarded by notifications.  VitaminD can pick up multiple movements in one second and before I put this in, I would get 3 to 4 announcements per minute.

If the light level is below 0.3, and there hasn't been any notifications for the past 3 minutes, then the Restlet does the following:

1.  Blinks the 2 ThingM (http://www.thingm.com) Blink1 that are on my iMac blink green 5 times.

2.  Posts the value 1 with the current time to Xively (http://www.Xively.com).

3.  Posts the message "Amelia is stirring!" with timestamp to Pushover (www.pushover.net).  This pushes the message to my iPad and iPhone.
