This video should have many more views than it currently has. Excellent information. Really appreciate the effort that went into its creation.

Thank you for the focal length comparison on the footage.

Wow! Thak you for your visualization. Now IEC 62676 standard gives the following numbers for D.O.R.I zones: Detection of people: 8 pixels per foot, observation 19 ppf, recognition of known people 38ppf, identification 76 ppf. For dori calculation I use jvsg lens calc. And your video gives quite a visualization of different lenses.
