Well, I would want to record each room for the whole work day in Myth,
then stop and let Motion take over ... I'm planning on streaming the
video feeds to a protected internet site for parents.
Motion wouldn't be anything other than an afterhours survellance mode...
Of course it'd be storing its video so that MythVideo would pick it up :-)

Yup.. For each Camera (or Channel), one tuner card would be used..
that is unless you wanted to stagger recording... In which this setup
wouldn't be optimal.

That's the beauty of it... You could do whatever before the 'multiplex' or
whatever afterward..
I originally planned on splitting the video feeds to the lobby to separate
tv's before this 'multiplex' idea ... But now I'm thinking that 8
cameras multiplexed together and going to a box where xawtv/other has
8 instances open, and sized just right on the nice 50" plasma in the
lobby, would be just perfect. ;-)
