A couple of points to help get started with this new software:
1. Clear your browser cache if anything doesn't look right. In fact, do it before you bring up the dashboard the first time.
2. You can test your web cam feed separately in a different browser window to see that the URL is correct. If you have a problem getting the feed to work in the Apex tile, right click in the tile then select "open image in new tab". Here's a link to a web site that has the video streaming URL for a variety of cameras
https://github.com/ingenuitas/SimpleCV/wiki/List-of-IP-Camera-Stream-URLs. Note that the URL they give you assumes you plug in your camera's entire IP or hostname address and port BEFORE the video stream portion. So their example of
http:///videostream.cgi means you would actually use
http://192.168.0.101/videostream.cgi.
3. Sometimes the web cam won't work because it wants you to authenticate. See #2.
4. The panels don't dynamically resize if you move between computers with different sized displays (for example one at work and one at home). You'll need to define separate Dashboards (you have 4) for that.
5. You can position tiles over the 'Unused Tile' panel - just make sure your cursor is positioned at the far left of the tile you're dragging so the cursor doesn't go into the unused tile panel.
6. If you have a problem getting your Dashboard to display properly, first see #1. If that doesn't work, try a different browser. It's been tested on Safari, IE, Firefox and Chrome but there's all sorts of different versions out there. If the browser version is the problem, please post back here.
