Greetings:

I want to hookup a security system with linux.I want to have magnetic
switches at all the doors and windows and feed them into Linux to
monitor. If a window/door is opened Linux captures the signal and can
tell which window/door is opened.Then sound the alarm etc.
How can I do this??

Thanks,
Bob
