20. RFI is an unavoidable nuisances for wireless alarm syst |
|
|
I showed that RFI is an unavoidable nuisances for wireless alarm
systems in several posts.
I had a case who muzzled my wireless alarm system for
more than 1 year before i discovered it by accident, no warning.
By measuring i found the original source of RFI, my wireless
headphone;
Notice that there was no warning and that pro's confirm, 20+ years of
theyre experience = no RFI warning.
I also have explained how wireless alarm system radio data is send
from sensors to the receiver and how it is jeopardized by collisions
and interferences.
I mentioned too that the frequencies used by wireless alarm systems
are authority interference unprotected ones and of free use by anybody
(you, car keys, light dimmers, headphones (the worst) and more).
I DON'T SELL any alarm system but can't admit, like i was induced in
error, that owners and future owners are mislead on the subject by low
level mechanics who have not the most elementary clue on radio
communication.
The only reaction where insults.. but coming from low level hammer
and cleaning cloth handlers, it will mot muzzle me.
WHY do manufacturers not provide any specification on theyre wireless
data communication loop; its the only thing who is different in
comparisons to wired systems.
Why do they not specify wireless receiver and transmitter data on
theyre wireless goodies or is it junk?

No. You didn't 'show'... you said. Very different thing. By the way, you're
stupid :-)
