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
(under linux) translates
to 8 surveillance cameras.

In the evening i'll try to boot a zoneminder-ready linux live CD to verify if
this the case with the smaller model (LMLBT44).
