How to remotely configure a Ring wired stick-up camera for a quarantined elder?

My moderately cognitively impaired 95-year-old mother lives on the other side of the country. She is now in quarantine, as am I. Literally no one is allowed in or out of her apartment in her independent living facility - meals, mail, etc. are delivered to her door. I want to purchase a wired stick-up camera so I can monitor her and communicate via voice without her having to take any action on her end. This camera appears to be a workable solution - except for how to get it configured and installed...If I walk her through it by phone, she is capable of opening a package, setting the camera at the proper location, and plugging it in (if the USB cord is already installed in the camera bottom and the wall plug attached), but there's not way she can scan and/or connect it to her wifi, or perform other similar technical tasks. Also, I want it connected to MY phone, not hers. I'm trying to understand if the following is possible: Can I purchase the camera and have it shipped to me; then I can connect it to a ring IOS app on my iphone. Rather than connect it to MY wifi, I want to MANUALLY enter the name and password for HER wifi (I have all this information). Then I will ship it to her, have her open up the package and set it up. Is this possible/advisable? I CANNOT get someone remotely to do any part of this setup, not to mention that my phone will never be on the same wifi as the camera. Bonus question: Is it advisable to order an optional battery for the stick-up wired camera, that is, can I charge and install the battery, then connect the power USB wire as well before sending it to her? This may not be useful since if the power to her camera is off, her wifi modem (Xfinity) is likely also offline. However, I don't know if the camera continues to operate (i.e. motion recording) even when there is no wifi available but then "catches up" by uploading the video when the wifi is restored; and/or whether the camera retains all it's settings even when unplugged (likely). Any advice or "gotchas" appreciated before I embark on this adventure. Thanks,Jerry K
