Subject: RE: [ukha_d] IR
Distribution ( What Cable )
The alarm cable will be OK for short
runs
(<5m) but it sounds like you're looking at a whole house and I suggest
you
need to use a screened cable for that since the IR signals are unbalanced
and
so will pick up hum and interference over anything other than short runs.
You
should keep the IR cables well away (10cm) from mains and data
cables.
I have heard people having success
using
UTP for IR distribution but I thought twisted pairs were only good for
differential/balanced signals like 100/10 base-T. Either they got lucky or
I'm
wrong - anyone care to clarify?
