what we're running to each current stationary camera is:
siamese cable (coax video, 18g power)
additional power wires (for housing, to reduce DC voltage drop off)
now for a future PTZ I can just throw in a Cat5 wire and call it a day, right? the Aventura rep is now talking about Cat5, baluns, and running power through the Cat5 too, but we already have the siamese cable and power cables ready to go, I just need to know what to add into the bundle to control a future PTZ cam...
