We need to run video over some existing CAT5 cables using baluns on
either end. The existing cables are all terminated with jacks on both
ends. One end is a patch panel and on the other end they are connected
to jacks which are mounted on the baseboards. We plan to make 8 foot
cables with an RJ 45 on one end, plug it into the baseboard jack, run
the cable up the wall and then connect the other end to the balun and
then to the camera. Would it matter if this short piece of cable were
CAT3? Thanks, Lenny


Sometimes there are so many variables that the only thing to do is TRY
IT!!! There is no obvious reason it won't work, but there is also no
way to guarantee it WILL work.

Understanding theory is all well and good. Applying it properly is
another thing. In the final test, the emperical results are what
counts.

One story goes that Thomas Edison assigned a simple task to a newly
hired engineer - calculate the volume of a light bulb. The newbie
measured the bulb at the points he felt were critical and spent the
afternoon calculating the volume. Edison looked at the numbers and
said "You're off by at least 10%". Edison then took the light bulb,
drilled a little hole in it, filled it with water, then drained the
water into a graduated cylinder. And showed the engineer his numbers
were off by 10%.


But Edison measured the inside volume. The engineer calculated the
outside volume. To proof this, the engineer submerges the light bulb
and measured the water rise.
To prove his measurement he measured the force to keep it submerged.

So he proved that Edison was wrong.
The glass of the bulbs in those times was very thick.
