Visible crew/equipment: When Elise is talking to Ted Garza over the phone, she walks into another room and the camera follows. As the camera goes through the doorway, you can see the shadow of the cameraman pass by on the wall next to doorway on the left side of the screen. True, Specs is following her, but you can see in the next shot that he's not close enough to her to have cast a shadow on the doorway yet.
Visible crew/equipment: When Elise has a vision of Gerald holding a girl captive in the basement, after he makes her drink the fluid to make her sleep, he turns and walks out of the room. As he does so, you can briefly see the tip of a boom mic dip into frame twice from above camera.
Visible crew/equipment: When Elise and Tucker open the hidden door, in the closeup of Elise, you can faintly see set-lights reflecting in her and Tucker's eyes. The the room in front of them is totally pitch-black, so there's no other light source that could be creating these light reflections.
