For the past number of years I have been a volunteer fire fighter at the Salmon Valley Volunteer Fire Hall near Prince George, BC. As with many halls, I noticed the technology options are fairly slim and the Radio communication system (Depending on your location) can be quite poor.
As a software developer, I decided to put together something that would improve the communication at our Fire Hall and provide my solution free to all other Fire Halls who desire to use it.
I have published all of the source code along with installation instructions on github located at the link below:
The solutions consists of PHP code for the server, and a few SMS providers to handle mobile notifications as well as an experimental Android app (which does not require SMS but uses the free service Google Cloud Messaging).
