I wonder if there is a way to link to my alarm and only turn the web cams on when the alarm is also turned on ??? Through some sort of serial link.

I've managed to construct a rf data link to interface my burglar alarm to my cctv machine. I should then be able to remotely monitor the state of my alarm system. I can also add more transmitters and monitor extra stuff like windows and doors.

Tx on the left, Rx on the right.
