Municipalities across the nation are deploying IP-based 802.11 wireless mesh networks for city-wide services, including cameras and microphones for police monitoring, and remote audio broadcasting. Once deployed, the standards-based nature of these networks make it easy for cash-strapped cities to use them for all manner of other IP-based services too.
In this presentation we examine a deployed and operational municipal mesh network designed by LeverageIS using Firetide hardware and Firetide's proprietary Firetide Mesh (formerly "Automesh") wireless mesh protocol. In the process, we decode the previously undocumented mesh protocol enough to (1) "tune in" to live feeds from the various cameras positioned across the city, just like we were in police headquarters, and (2) inject arbitrary video into these streams. There's a demo site for you to see the municipal camera streams for yourself, and our code is included. We'll cover wireless mesh networks and other basic theory, so no prior technical knowledge is required.
