I think they are multiplexed, at least the big model LMLBT44, can support up
to 4 full rate inputs or 8 multiplexed video inputs, which in zoneminder=20
(under linux) translates
to 8 surveillance cameras.
At work we have deployed the above successfully (LMLBT44 + ZM under debian =
+ 8=20
cameras) .
In the evening i'll try to boot a zoneminder-ready linux live CD to verify =
if=20
this the case with the smaller model (LMLBT44).
