Does it make any sense at all for my case? If that was possible i would have /dev/bktr1stCam -> /dev/bktr0, /dev/bktr2ndCam -> /dev/bktr0, /dev/bktr3rdCam -> /dev/bktr0, /dev/bktr4thCam -> /dev/bktr0, so that zoneminder would run 4 instances of zmc, which i can deal with, and effectively solve my problem, (although not in a fancy way). What do you say? > > --Mark Tinguely. -- Achilleas Mantzios
