Jones chucked a long fat bit into the drill and put a hole all the way through the reinforced door, then fed the little webcam’s USB cable through. Using a web of zip ties, duct tape, and drywall screws, he mounted the little eyeball to the inside surface of the door up near the top. Meanwhile Sharjeel had zip-tied the cable and its extension down the length of the RV’s central corridor to its kitchen table and plugged it into the laptop. A long adjustment procedure ensued in which Jones would close the door, leaving Zula alone in the room, and walk up to view the camera’s output on the laptop, then tromp back and open the door and wiggle the camera this way and that, getting the angle just right so that (Zula supposed) it could see all parts of the room.
