I am connecting the camera to an IP Server box (Small black box with 4
video inputs that sits on your lan. I took another camera and connected it
into the port of the IP Server and the port worked.

Its a head scratcher all right

Are you using the old power supply from the old camera, or did the new one
have a different one (the new camera sounds as if it has a BNC connector
from you description, this normally means it is a professional type camera
not a domestic one - (The professional ones usually require 12v DC or 24V
AC)

Your wiring sounds fine to me, my cameras are powered with alarm type cable
from multiple PSU's, with the video signals on separate cables back to the
multiplexer, so the power ground (0v) and the video ground are separate on
my install too.

Can you connect the video to a monitor or TV's AV socket to see if that
works?

Sparks...
