By instructions to set up monitoring, you mean the remote viewing via internet, correct? If so, you can see the how-to at the following link:

The delay you see while watching remotely and the refresh rate both depend heavily on the framerate and resolution the DVR is recording at , and also on the download and upload speeds of the connection at the site of the DVR and at the site of the PC you're watching it on, so it's extremely difficult to give you an exact answer to your question. Generally speaking, if you were using a 1304NET at its lowest resolution setting and had it running at 30 frames per second, even worst case scenario you can reasonably expect to see 5-7 frames per second, however I would again like to emphasize that there are a huge number of factors in play and it's impossible to guarantee any specific number without testing.
