You can check out a company called Pelco (www.pelco.com).  They design
cameras and mountings for security systems with PTZ capabilities and
all sorts of other goodies.  We're using them for a site security
project.  I don't know if they have serial control specifically, but
I'm fairly certain they have network-controlled devices that could
work out for you.
