Re: Long distance IR beams interfaced to RS485 based alarm system

The fatal flaw with radio communication is spectrum jamming. If you
cut the phone lines the GSM radio will kick in. But if you use
http://www.phonejammer.com - there goes the GSM link.

One should try and run http://scratchpad.wikia.com/wiki/RS485 wires or
even http://scratchpad.wikia.com/wiki/DsLam twisted pair to all the
nodes and have some permanent http://scratchpad.wikia.com/wiki/MeshNetworking
Wi-Fi backup system to stream to a distant premise alarm data in real-
time. The mesh networking the wiki refers to is the http://www.locustworld.com
Ad-hoc
protocol it contains over 400 page on installing and operating an Ad-
hoc mesh. Zigbee for example uses some ad-hoc mesh protocol.

The only alternative to phonejammer on the GSM spectrum is to build
your own http://scratchpad.wikia.com/wiki/GpsAndGprs GSM modem by
hacking the patents that detect spectrum jamming.

The present alarm systems with all their cryptic input panels is a
joke. We need to use an embedded ARM processor running Linux and
Python that accepts a text file or some XML standard.
