Does anyone know where to get a data extender for a Clarity system? The part number is 70049. Can't get any response from the company to order it. Or, does anyone know who manufacturers this for Checkpoint? Thanks a ton!

I'm in the process of designing an IP system for a multi building application. Each building will be going back to the control room via fiber (Separate network). Each building has about 20 cameras, mainly PTZ. How many fiber strands are needed for this? Is there a such animal as a simplified calculator? Thanks.
