i used 7 cams the other day
the problem is if you use the cams on a slow computer then your stream will take foreva to load also over wireless is probably causing the slow stream
used on a asus eee pc which is pretty slow, cpu usage at about 80-100 when using icam using internal cam and external Microsoft cam
4x on the quad core had no problems
1x on a 3500+ amd wireless about 50m away
all linked up using the same user and pass after a little trouble
also made sure to forward ports as this was and issue with 3g
and put your quality a little lower so the stream over wireless comes up faster
some issues with icam i have noticed is that the server is not refreshing quickly when changing password and user so takes forever to load. and if people are just using a name like e.g. fred and a crappy password its not going to be very secure make sure to use something decent not just 1234 or something like that, mate of mine using it just picked up some other user. so both of them would be looking at each other this problem should be fixed but then hooking up more that 1 pc would be affected so if you want to be secure put a better password !!!
all and all this software is ok but needs to be separated from the server like i said last time so we can just setup the program on the pc and connect straight away like dorgem...
