I've installed a number of Spectra IIIs, they're good units; I hear the
Spectra IVs are a good step up, but I've not used one yet.

I'd suggest running a single piece of Cat5e to the camera and using
baluns to run control, video AND power over a single line -
http://www.nvt.com/applications/vpptz_218.html for example. If you're
using PTZ systems that use Coaxitron protocol (control signal is fed
over the coax) you can use a solution like this:

It costs a little more this way, but it's a hulluva lot simpler than
pulling multiple wires of different types... plus, you then already have
Cat5e in place if you ever upgrade to IP cameras later.
