It would be nice to be able to have multiple WiFi networks that the cameras can connect to - preferably with a priority (i.e. connect to this one if available and if not connect to that one, etc). My specific application will be a couple cameras in my car. When the car is at home, have it connect to the house WiFi, but if not, connect to the cellular hot spot that will live in the car.
I doubt we are going to see the ability to remember multiple wifi networks on the wyzecam due to hardware limitations.
However, there is a workaround that might work for you. If you get a travel router such as this one:

You can set it up to broadcast a single SSID that the wyzecam can connect to and have it connect to and bridge multiple external SSIDs to the camera. You would, of course, need to provide power to it in your car all the time.
