as far as i remember, geo control ctr supports 64 cameras across from mutisites, and per ctr can support up to 4 monitors if graphic card itself permits. can't wait to see it...
once visited taipei secu show, some small factories are making some fancy dvr... by fancy, they look futuristic like starwars... but, i have to say, customers consider that as toys.
agreed with thomas, it's a human factor, lots of customers are using PDP to display many many partitions per monitor... that's crazy since in fact, for the really important one, they still have to buy geo loop card for looping video to a single lcd panel...
