So they put the custom-made camera, which is one-of-a-kind, in Leila's room in order to catch Toby. Fine, got that. But what about the camera in the hallway, near the stairs? How can that camera pick up Toby???
Leila had 2 cameras in her room. One was aimed at her bed straight on, the other was to the right of her bed, and that's the one that picked up Toby when her mother and the friend were in her room. And then there's the camera in the hallway that also picked up Toby.
