Questions about verified response / guard

That doesn’t answer his questions about the camera verification.
Doea a guard still get sent to the house if it is visually verified by the owner of the home via camera ???

To add on to this…

Who is this guard that comes to the house?

Who employs them?

How far away is this guard?

How can they verify a fire if it has not yet reached the external parts of the structure?

These are questions that I find ring has been unable to answer. If ring is imposing a $75 fee for such guard, it would be nice to have some answers.
