Visible crew/equipment: When Trevor is uncovering the ECTO-1, you can see the camera's shadow on the left of screen and even briefly on the car front.
Visible crew/equipment: When Gary opens the trap next to the 2 school buses, he is wearing a cable attached to an earpiece on the right side of his head. The kind of cable actors wear to receive instructions from the crew. There's no reason plot-wise for him to be wearing it (he isn't receiving any instructions from the kids, who are right next to him).
