Hardware and Software Details
The camera (with remote pan but no tilt or audio) is an analog home surveillance model (PanDome SecurityMan) with coaxial output and requiring 120V AC power at the camera. The analog camera output is routed through a 150' coax cable, converted to digital video(DV) using an ADS PYRO A/V link, fed through a firewire cable to a Mac PowerBook G4 laptop and then captured using the free program QuickTime Broadcaster. The DV stream is broadcast to the server at 15 frames/sec with 320x240 resolution. We're using a server at the University of California, Davis in the LAWR department. The server hardware is also a Mac laptop running Mac OSX Server. It uses the program QuickTime Streaming Server configured to reflect the live video as a unicast stream to each client computer on the internet.
