Yes, the DNS settings are accessible through the camera web page. I think there are multiple ways of doing it, and it vary based on the model of the camera. I have typically taken the name from auto to manual, entered in axis-camera, and switched it back to auto and saved. I have seen Mark lead people to the Bonjour settings. To test this, use a web browser or command line to test that "axis-camera.local" works in the same way as the IP address would. So you can ping from the command line, or enter the name into the URL of the browser and it works the same.

As for the custom DB comment. I was not paying attention and was thinking that you were using the default DB. For that, you have the source and building a custom DB gives you the opportunity to probe and debug a bit. Though the code gets deep fast.
My guess for the SmartDashboard is that you add a camera display widget and edit its properties. I'm not sure if you enter cam0 for the address or the robot's IP where the server will be running. You may want to check back with screen steps later and see if it has more explicit documentation.
