Long ago I played with a dlink camera and as was able to figure out a URL that would get a single frame. You might log into the https interface and look at the html on the live view page. Also check out the zoneminder wikis and similar for the access methods. I would not be surprised if you can find into for your camera on the web someplace. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
