Yes....just use the same secure username/password combo in both icamsources and in the iCam app. Since you'll have multiple cameras, you'll definitely want to check the "auto config router" box on each computer's icamsource, and make sure uPNP is enabled on your router. If it doesn't immediately work, try rebooting your router and computers and try again. If you still have connection issues, you'll have to set up manual port forwarding.
