How to Build a VoIP-Based Baby Monitor

February 17th, 2011 by cmatthieu

Two members of the Phono/Tropo team, and soon a third member, have recently added new babies to their families. Congratulations Mark, Justin, and John!

All of this excitement got the hacker in me thinking…  What would a modern Baby Monitor look like today?  Armed with the Phono and Tropo APIs, I started hacking and 2 hours later had the following example application to share with you!  Here’s the link to the demo.  Let us know what you think! http://phonophone.heroku.com/babymonitor.html

Phono, the jQuery WebPhone from the Tropo team, runs in the web browser to monitor activity in the room where it is running.  Tropo is used to manage the baby monitor’s conference room (based on the access code) and the dial-in numbers to listen to the baby monitor via PSTN, Skype, SIP, or iNum.  The Phono side of the conference is unmuted so you can hear activity while the Tropo side of the conference is muted.  You can have many people (Mom, Dad, Grandparents, etc.) dialed in listening to the same baby monitor using any combination of the access channels listed above.

Check out the Phono Blog to learn more about this demo and see the source code!
