Must be a translation/proof-reading error. A camera 1m above people's heads would be perfect for capturing faces.

I think they mean surveillance cameras run at an angle that makes automated facial recognition impossible.

Today’s state of the art facial recogition systems work with close to +/- 90 degrees of head pan and tilt. It’s really quite impressive.

Yes, but this is in an article about people being captured by facial recognition surveillance. It appears to contradict itself. Maybe it's a typo?

That seems unlikely.

Catch faces?

Hit heads perhaps?

As in, “Ouch! I caught that camera with my face.”
