I am the guy who had the done the old 1.23.3 zoneminder port some years ago, and i am thinking of installing/testing the new 1.24.4 port, submitted by bsam@FreeBSD.org. Besides the basic functions, i am thinking of re-using some old techniques by which i controlled the home alarm via a NC/NO circuit (basically it was an enhanced door contact), driven by an old zyXel modem, which in turn was driven by a small perl program driving the com port, and which was called by a deamon reading zoneminder shared memory info directly. That way i could trigger the alarm system getting into alarm state, whenever zoneminder detected motion, in a fully controlled and programmatic way. Now i am thinking of re-doing this, a little bit more modern, if possible. I was thinking of some relay board (instead of the old modem), possibly ethernet controlled (to get rid of all the obsolete com port programming), and such. Also i will scrap the old NO/NC solution (circuit embded in the door contact), and i wil use instead a new dedicated wireless transimter i bought (same brand as the alarm system), which is also NC/NO and receives two inputs and corresponds to two zones. So i am thinking of assigning 2 cameras as two disctinct zones in the alarm system. That is the rough idea. What would you guys have to recommend (regarding the relay?). I do not plan to use this relay for power/lights on/off and such, at this stage it will function solely to drive the alarm transimtter, (which in turn will drigger an alarm to the central alarm control panel) Thanks -- Achilleas Mantzios
