difference if you're using telephone lines and cellular, ......... which one
you make primary ......... as long as you supervise each method via the other?

i am all with you on this one...
been sending my alarm signal over ethernet for a year now and i didnt had
one single issue yet...
but i can say the same for my land line..and i know that one day i will have
some trouble ..from the land line or from the ethernet connection...nothings
perfect!
the only problem i see about sending signal with both the internet and land
line is if you use the same copper wire for both..(adsl and telephone coming
in by the same wire..)
that would be totally useless to prevent the lost of communication in case
someone cut the copper..
unless the ethernet communication is supervised...but its not all the
internet modules or panels that use bi-directionnal communication..... and
you have to set up properly the routing device locally if this connection is
used for something else(most likely)
i have a router here....(linksys) on an ups...its pretty stable..but it was
not the same before the ups...was freezing every few weeks...
so all in all this is about the same thing as a cell backup...just need to
learn something new...
