This is a separate issue. Your camera is probably hooked up via a switch.
This is a limitation of the Prosilica SDK; it can only enumerate cameras
with IP address on a local subnet. If the camera is not on the local IP
subnet, you can still open it, but you have to know the IP address ahead of
time. This is why we have the "How to Determine Your Camera's IP Address"
tutorial, in case the camera isn't visible to the SDK and you've forgotten
its IP address. As long as you can open the camera using the
prosilica_camera node with ~ip_address set correctly, there's nothing to
worry about.
