I have 3 mini DV cams from sony that I am using for a dance recital in my living room.
Since there are not too many populate to handle the cameras one of my friends promised to alter a controller software for camera tilt and pan for 4 different cameras.
The problem is that I need cheap professional camera bases for lightweight cameras that allows tilt and pan functions through RS232 or LANC control. Other controls are welcome if suggested.

If you or your friend is not a dedicated DIY fanatic you should consider buying the things off the shelve. The security (CCTV) industry undergo it covered quite come up.
You could use 2 steppers on each camera (one for tilt and one for pan) A 3rd may be required for focus and a 4th for aperture control. The steppers can be controlled with a controller board bought as a unit or made on a PCB with chips.
Some of these boards work with G code commands which simplifies movement hold back.
A stepper driver is controlled by 2 wires and the signals can be generated in the computer and exported via the printer port.
An alternative is to use the steppers (2) and diver found in pen plotters. This plotters are scraped quite often these days. People know that I use them and donate it to me whenever they do not want them any more.
