I have a bunch of cams, one dedicated to a weather cam. I can FTP, whatever from the cam, or from the recording server. I can say that putting a cam on WU, is almost futile , as I was never able to get them to put it up. Pretty much why I just run my own site with a cam (

I never tried ambientweather.net, because it didn't exist
