Security or Stickup Camera with 4G LTE capability

I would really like to see a Ring Stickup or Security camera model with 4g LTE connectivity. I have many Ring devices already, but I’ve had to switch to other systems to get security cameras with 4G LTE capability. I’d really like to stay in the Ring universe, but you just don’t offer what I need in this regard.

My first need is a remote solar powered security camera where there is no power, no internet, no WIFI, no anything of civilization except for 4G LTE cellular service. My second need is a solar powered security camera for use in an RV storage facility where my only connectivity is 4G LTE cellular service.
