Does anyone know what the range is for a ring doorbell camera, not just horizontally but vertically too?

Looking to buy a doorbell camera but need it to cover the landing below flat too which is about 7 steps down from the front door.

Our flat door is on the right (drawn in red) as you come up the stairs and would want it to pick up as soon as someone came onto the landing from the stairs on the bottom left, where I've marked the green x.

I'm not sure if these cameras would have a wide enough range of motion to pick this up or if there's a better option out there? I would be mounting it flat on the back wall directly in front of the stairs at our door.
