Re: [Motion-user] Motion capture on GPIO trigger on Raspberry PI

[Greg B. <gwb...@gm...>]

Oh, and I forgot to add that originally I was using the 'Motion' package
along with a Logitech 960 (?) USB camera for motion detection and I wanted
to trigger the Raspberry Pi camera if the door opened but I liked the
'trigger motion via the IR sensor' method so much I dumped the USB camera
and Motion (which is an excellent package, by the way) in favor of sshfs,
Python and the IR sensor.  Eventually the door and window inputs will be
monitored from Z-Wave.. but that's down the road (once Amazon sends my USB
Z-Wave thingy that is).
