Wireless Web Cam Broadcasting

How (what technology) would I go about setting up a
wireless webcam on the roof of a building so I can
transmit video of construction progress of an adjacent
building to the internet??

Need:
1) internet service (cable, DSL, dialup, satellite, etc.)
2) modem for your internet service, usually is provided
3) wireless router to interface between your cam and modem
4) wireless webcam
