Please log in for more thread options I need some help/advice on where to get started. I am writing some software (more details on that later) that will essentially serve as another sensor in the home (intruder detection sensor). Where I am stuck is that I don't know how to "talk" to the home security alarm panel. I have USB and Firewire out of the computer, and I would absolutely just LOVE if I could simply plug in a USB cable that was wired at the other end to open/close the alarm circuit. However, I doubt that is possible. So, any advice on this is much appreciated. REgards, Greg Dameron | ||||||||||||||||

Please log in for more thread options Couldn't you just but a relay/control board, have the software fire the relay, and tie the relay to a zone on your panel? Lots of other experts here (I'm not) but....... trying to interface with your panel at a software level seems overly complicated; and for most panels, probably unlikely. | ||||||||||||||||

You should probably look for one of these panels, or are you trying to work with an existing panel? I've never seen USB or firewire directly into a panel, although a USB to serial adaptor could be used in the case of a serial interface alarm. -- Andrew Gabriel Consultant Software Engineer | ||||||||||||||||
