Visible crew/equipment: When Neo is going to open the door to enter the Oracle's house, you can clearly see a camera on the doorknob. There's a sheet over it painted to look like the wall behind it, with a representation of Morpheus' tie too, because he's blocked by the camera. (01:07:40)
Chosen answer: The pills are the Matrix representations of computer programs. The red pill contains code designed to disrupt Neo's input/output signals, so that Morpheus' team can pinpoint his physical location in the real world. Once located, a signal of unspecified type is sent from their ship, which presumably serves to wake Neo up.
