@Randy_Rands, have you ever tried to access the video streaming using the urls you mentioned in the browser directly? If it is working in the browser directly, but not in the dashboard, and you are using the Chrome browser, you may have run into the Mixed-Content issue.
You may also want to try the following URL format that I found here.
http://192.168.1.120/cgi-bin/snapshot.cgi?chn=1&u=admin&p=admin
Let me know if this helps.
