this is a comparison of a v4 I have mounted inside a window, lower and just to the left of where the Floodlight pro is mounted.
I wanted to share, so that you could see the difference in the field of view of each:
V4: Field of View: 115.8° diagonal, 98.5º horizontal, 53.1º vertical
Flood light Pro: Field of View: 180° (camera points down enough to get the sidewalk up against the house):
