Without pulling it apart - there is no way to identify the manufacture. ADT
has done a great job of keeping customers out of the inner workings.

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.
