I and a few other media artists use the "elmo" PTC100, its cheaper than the canon's I was looking at the time.
With Canon you had to agree to a licence to even get the protocol, elmo just leaves it out there. They are a pretty good company also (meaning they have not pissed me off like others).
You can't do a slow pan with these cameras (despite the protocol sheet).
They also say the life is about 10,000 movements, but I've done probably a 1,000,000 and still going strong.
I have an abstraction in the CVS for controlling it (uses comport and py to do the parsing/communications) Works with the USB-rs232 adapter I used.
If you end up getting the Sony it would be great to add an object to the ptz-camera collection. The infrastructure is there to give any command, and get back messages from any of 4 in a daisy chain, just not ll the details are implemented.
anyhow just letting you know.

I'm looking at the specs for a Sony PTZ cam which uses Sony's ViSCA protocol. The manual gives the commands for communicating with the cam, but I'm not sure if it would work with an existing Pd external or not. The control machine will be running OSX so a USB-RS232 adapter would figure into the equation. I know very little about serial port programming and need a little help determining if the cam is an option or not.

I've worked with a VISCA cam a few years ago. It just uses 9600 baud RS232 serial, so [comport] can handle it. The harder part is parsing incoming messages.
