This is a very Hacker News answer, in that you wrote three dense paragraphs that are all technically correct, yet also completely divorced from our practical reality that has smart home cameras in it. What is the obvious implementation out there? They just have both. They have the cheap 8-bit microcontroller from 2 decades ago transmitting on the low-bandwidth home automation network, and when it is decided that the camera should stream, it wakes up the beefy Ambarella or Socionext SoC to send its video feed over classic WiFi to the vendor cloud, and whoever wants to receive it just gets a stream URL back.
