I came here to look for this answer. I was hoping that a license is needed only on the machine with cameras. Even the two license types differentiate by the number of cameras used. I thought I could install BI5 on a couple of other machines without licenses and periodically connect to the server with cameras. It seems illogical to require licenses for the "client" machines without cameras. Does anybody know if it's an overthought or an early "glitch", or this requirement is stated somewhere?
