I’ve had a lot of recognized faces and the feature has worked as advertised, but I use v3 cameras inside looking through a window, so I realize that isn’t as common as having a camera mounted outside.
To be fair to Wyze, I know two people with cameras with face detection from other companies. The only one that works well is a doorbell cam, but that’s mounted and angled specifically to catch faces. The other person has an outdoor camera mounted above the door and angled down. That camera doesn’t catch faces either.
My guess is that AI has a tough time detecting individual faces when the cameras mostly see the top of the head and the face itself is mostly obscured.
Still, I’m sure the systems will get better with time and enough samples.
