What specific software are you looking for?
The viewing software that allows viewing of multi cameras? (required logging in to open and close)
the software to locate the IP camera?
If you know the IP of the camera you can just open your browser to that IP EG:
http://192.168.0.123if you enabled port forwarding in your router and or changed the port then you'd need to add ":(port#)" to the end of the url.
