As far as remote pan/tilt cameras go, the best fit for your scenario would probably be
Sony BRC300 camera, with controller(s), such as the RM-BR300. Parkervision is also a contender with their Cameraman series of cameras.
If you are determined to record each camera and edit later, you can either record to DV tape, or will need to get into some kind of hard drive DV recording scenario, such as
Videonics' FireStore. Then you can download the video onto a computer loaded with
Sony Vegas / DVD Architect, edit, and create DVDs or streaming video or whatever. Recording each camera on a seperate device (called iso-cam) and editing later can be very time intensive; I recommend live switching the video, in which case you will need a video switcher. Since the Sony BRC-300 accepts genlock, you choose to use a genlock or non-genlock sync switcher by Sony, Panasonic, Videonics, DataVideo, etc.
Audio would come from a mixing console output or dedicated audio mixer.
I recommend contacting a dealer or paying a consultant to design the system and draw up estimates based on different scenarios of recording on tape or hard drive, switching live or iso-cam, etc.
