Can you identify by model number(s)?

I suspect that the fact that they're using wireless sensors is part of 
why it works.  I suspect most of the issues with other security systems 
is with horrific wired inputs to a central control unit (Pin One issues 
and non-existent bandwidth limiting), and their failure to tell their 
installers to use twisted pair.
