I am looking for a video doorbell type device that does NOT require the use of a smartphone. This is for my 90 year old mother who does not have and cannot operate a smartphone, and needs something SIMPLE. She DOES have WiFi in the house however. If there was a device that used wifi but somehow used fixed monitoring, that would be ideal. Do not suggest a tablet --still requires selecting apps and recharging--not acceptable. A separate product she could also use is the RING floodlight cam, which can be powered from the electrical boxes that house her current conventional floodlights. But again, monitoring is the issue, because although they operate from wifi, they require a smartphone or tablet.
