[kwlug-disc] Cabling for video

We (church) are bringing in projectors, screens etc. (We already have 
sound.) We want to run the signal over ethernet cable. We have about 
1000ft of Cat 6 courtesy of Cedric. (Don't worry, I have other uses 
planned for it.)

Anyways the manufacturer has stated the following: If you do not use our 
cable products, you will not get any support. When asked if we could 
test our plan with their devices, they said go ahead, but if you have 
problems we will not take them back. (ie we damaged them.)

This is the manufacturer's spec for cable.
Kramer's BC−DGKat7a23 is a shielded twisted pair (STP) cable designed as 
the ideal companion to Kramer's twisted pair digital 
transmitter−receiver sets to provide optimum range and performance. The 
cable is optimized for the new 10GBASE−T applications as defined in IEEE 
802.3an and for PoE+.

I have a few questions:
1. This cable is shielded. The longest runs we are talking about are 
going to video monitors up to 150ft. (The projector runs will be less 
than 50'.)
2. This cable requires soldering the shields to the metal outside of a 
special RJ45 connector.

Needless to say, this cable and its connectors are expensive. My baloney 
detector is going strong right now. To me the additional cost of this 
specialty cable far out-ways the benefits.

I believe we will bite the bullet on this one, as we cannot live without 
the warranty. But just for my sanity, what do people think?

I feel that it is a lot to do about nothing.
