I pretty much use the Pelco Spectra Domes, but many are similar.  They use
either RS-RS 422 over a single twisted pair for control, or in some cases
(like Spectra Dome) they can have control over the same coax as the video.

Also, it depends on what you are integrating it with.  I use mostly
Dedicated Micros DVRs and they integrate nicely with Spectra Dome cameras
and have full control capability over twisted pair locally and by remote,
and 95% control over coaxitron.

Client software and web interface both give access to PTZ controls, but PTZ
control for this pair does not seem to be fully integrated in most of the
smart phone aps except one that is server subscription based.  I have not
fully tested the newest ap from DM as Robert Chou's Ip Cam Viewer Lite will
access DM and other brands of DVR, NVR, and IP camera making it more
flexible for many of my customers.
