I found Advanced Port Scanner (freeware) to be a little more helpful than standard port scanners in cases like this. You may want to give it a shot.

Actually surprised masoko's suggestion didn't work; I refer people there all the time and this is one of the first times I heard someone not able to find a URL. You may want to see if the camera is listed under another name; I've also seen it listed as Fujikam; Vimtag is the US LLC distributor. Scanning with APS may reveal yet another name of the actual manufacturer which you can then try in ISpy again.
I'm not sure, I thought the port scanner I am using (http://www.advanced-port-scanner.com) would tell me. And I am on the same network but I don't know what "layer 3 or higher" means, I'm new to all of this.
