I have my computer hooked up to the console of my DSC burglar alarm though several feet of doorbell wire. It's connected to the parallel printer port which is still on modern motherboards even though no one owns a printer with a parallel port any more. The port can easily be used as inputs through a C library. I wrote a simple daemon that starts motion when the alarm is turned on and kills it when the alarm is turned off. |
