I rewatched your video and managed to get a good video by moving into the dark basement.
Not sure why the line of text was split like that.
Oh, and another interesting note. Using my new iPhone Xs, I got lots of mirror images of the lights that the algorithm had difficulty with (crappy lens design). I got a decent model by cropping as close as possible on all sides and fiddling a lot (even one digit at a time) with sensitivity and minimum distance settings.
Pretty impressive software, guys.
