Corner Mounting Cameras - What Angle Should I Use?

Corner mounting a camera to monitor a whole room comes up fairly often. How wide should you go?

Here is an answer based on comparisons from our Camera Calculator:

Notice 90° is actually too narrow for the full room, missing some of the sides and the bottom. By contrast, a 120° shot gets that missing area.

I suspect this is one of the reason you see a lot of HD cameras having 100°+ AoVs.
