Isn't there anything that will transmit small data to the cloud via the cell network? That would be ideal.
Do you have an old smart phone laying around? Find an app called Alfred and put it on your phone, your mom's phone, and the old phone. You can configure the app on each phone as either a camera or a monitor, and you can access the camera phone to configure it from anywhere on the planet; turn the light on/off, talk through the speaker, record video, set motion detection, use night sight, the works.
It is ad-based, but free, and probably of very questionable privacy, but as long as the camera phone is on, you can completely control the configuration from your app on your phone even if you're vacationing in Japan.
I had two old cell phones that I had set up as cameras and my phone as the monitor. The only reason I switched to Wyze cameras is that they were on sale and I had no real means of "mounting" the cell phone anywhere and they constantly fell over.
This, of course, would require the old cell phone to either be connected to her wifi, or be an activated phone ($$$) to use a cell network. You should be able to see her wifi configuration info next time you link up. Then you could mimic her AP at your home, set up the smart phone, and send it to her with the instructions of "plug in, turn on, put on a shelf."
You MIGHT be able to do the same thing with Wyze. They could at least be tricked into connecting to her wifi, but the real pairing comes from scanning the QR code on the phone that is setting it up. It's possible you could mimic her wifi and connect them to your phone, then send her the cameras and share the feeds with her. I do that in the spring with my mother. She loves watching bird nests, so when the finches build a nest on my back patio, I turn the camera to see their nest and share the link with her. The only downside I see to that is that you'll have to find some way of getting the Wyze app on your mom's phone. She can view it in a browser, but it's not ideal.
