Found a solution!
I found a post that mentioned a tablet's browser blocking username and password in a URL so I'm guessing that is the problem.
- But in another post I found a solution: https://community.hubitat.com/t/dashboard-tile-with-jpeg-image/51418
That post showed the example link of: http://mydomain.com:40027/action/snap.cgi?user=user&pwd=password
I gave that format a try (http://192.168.1.211/videostream.cgi?user=Username&pwd=Password) and it works perfect!
My understanding is that the entries after a "?" aren't standard but are whatever the server is setup to accept as parameters. So I do wonder if the variables of "user" and "pwd" are an actual standard, if they are just common so you can expect them, or if I just got lucky.
I'll take luck so I can use my less than $10 low res (low data rate) camera!
The last thing it's getting is I'm adding a cheap smartphone add on wide angle lens so I can see everything around the gate bell.
Thanks @thebearmay for the prodding! It helped me keep searching things until I found the alternative.
