Are these crops?  The AOV seems pretty much the same.

Yes, as we explain above it, that's an image from the 2.8mm camera, showing how the illuminator of each of them varies. So it's easy to see it narrow.

But fair point, we should put in a full field of view from each camera for clarity. We'll mark all that up better.

You’re right, you do say that, it’s clear now that I read it again.

btw, how much ambient light is present there?

do you think the beam angle would be easier to discern if it were darker?

That was outside, with the lights off, and about 0.05-0.1lx, depending on distance. The pattern might be more visible if it were darker, but it's pretty hard to find an outdoor scene that's much darker.

Those are the ones of IR, not the lens.

Since they didn't have pics of actual coverage differences between models, they wanted to make it easier to compare the other aspects I'm guessing. And use the IPVM calculator instead.
