Our Company has been installing IP PTZ's.  I don't have a whole lot of
contact with them as I am pretty much pigeon holed into fire alarms.

One my boss showed me had the fastest movement I have ever seen - I was
pretty impressed.

Being IP - they are controlled from a computer.

I'll see if I can rustle up some info.

I think they're POE (Power Over Ethernet) so the only wire you have to
run is a Cat-5E.

I'm not a hundred percent certain the PTZ's are POE but I think they are.
