If you like to purchase a home alarm system go WIRED.
WIRELESS alarm systems are UNRELIABLE when there is a "low power"
Transmitters in the vicinity operating:
- ON the wireless frequency, SATURATING the receiver, provoking
INTERMODULATION, having HARMONICS, OPERATING beside but in the
receiver bandpass, ON the IF frequency
- and more...
In essence the problems caused can be defined as a "Radio Frequency
Interference (RFI)" and is the fact that by no way two (or more)
systems can use simultaneously the same receiver input.
THIS RFI muzzle and jeopardize completely the normal operation you
expect from an alarm system.
Several pro's admit now that RFI exist and can't be avoided.
In the same post they say that:
- in "modern" systems RFI is detected..
- they had no warning since 20+ Years (they call that experience).
Question:
Are those "modern" systems with that marvelous RFI detection
circuit existing since 20+ years?
WHAT CAN BE CONCLUDED OUT OF THAT?
1. The UNPROVEN and manufacturer UNSUPPORTED RFI detection system
is inefficient or don't exist;
OR
2. RFI is muzzle the system and owner/monitoring station is
NOT ALARMED/WARNED, in that case its easy to say that
they had no warning since 20+ Years.
This last item (2.) proof that RFI is NOT WARNED at all.
"So called pro's"(???) in the alarm business obviously don't possess
the meager intellectual capacity required to understand the basic
concepts of wireless data exchange principles.
Don't overestimate "so called pro's" talent to judge others either.

Wireless won't work in Belgium because Belgium doesn't exist.

Belgium is a "virtual" country. It only exists until you shut the computer
off... :)
