David has a vacation home and has WiFi cameras in it to view remotely. His problem is that when the service goes down, it could be days before it gets repaired. Could he use a cellphone and TING? Leo says that cellphones can be used as a "hotspot" and they can use their data plan to reach you when you need to view it. The question is, would TING let you do that? Other mobile services do, but they charge you and cameras use a lot of bandwidth. So check to see if they only work on movement. In principle, that could work.
