What is the real Field of View (FoV) of the SJ4000 / Wi-Fi ?

I can see that the question has been asked on the web without getting any real answer...

The official datasheet mentions a AOV diagonal of 170°. Is it really this? So what is the horizontal FoV?
How to calculate these values?

Thanks in advance for your help
