(1) Licensees must not use multiplexing and quad recording devices for required surveillance, except that they may use:

(a) Multiplexing or quad recording devices on entrances and exits to the card room; and

(b) Quad recording devices to record the movement of drop boxes between tables and the count room.

(2) "Multiplex recording" means combining multiple video inputs into a single signal by cycling through the separate video inputs with the view rotating among different cameras in a predetermined order, recording each video input consecutively in the cycle. Multiplex recording does not provide continuous recording of each video input because the amount of time lapse in the cycle depends on the number of video inputs.

(3) "Quad recording" means four separate video inputs that record continuously and combine into a single signal displayed on one monitor with a view of each video input.
