Andruav and/or multiple cameras

Hi All
We are looking at a move to Andruav and away from Herelink in our current Rover build for longer range and the ability to be able to control the vehicle from a different location.
I have a few questions that someone may have come across.

Can anyone recommend a standalone system for operating multiple cameras? via LTE/4g?

From reading the Andruav docs this system is only capable of using the Mobile camera, is this still correct or is there a way to work around this?

Is there an alternative to Andruav that would allow multi-cameras?

We are currently using CUBE Orange, and Herelink for auto missions.
