Frank Olson,
As you seems to know that much tell us WHAT is the difference in the
actual wireless systems subject receivers and Radio Frequency
Interferences (RFI) so that the readers can appreciate your immense
and marvelous knowledge.

The fact of the matter is that ANYTHING can be jammed... Even hardwired
systems can be disrupted... Given the improbability of such an attack on
either RF OR hardwired systems, your whole line of thought is moot. IF, and
this is a major IF, you find yourself in the category that such an attack
would be used against you, special installation procedures would be
dictated... In THAT case, RF devices would not be recommended. |

On wired systems RFI can be reduced by additional line input low pass
filtering, with wireless its impossible to improve.
BUT, Aegis has you seems to know that much better, explain the level
of RF power required to disturb wireless versus wired (even if no
additional filtering is used in the wired type of alarm system).
I have already mentioned that but it seems that you know better, so
give some relative required power figures...
