4S DEEP ELECTRICAL BOX
NOTE: You should install the camera module into the back box before installing the back box into the
surface. When installing the back box into the surface, rotate the camera module to access the mounting
holes (refer to Camera Module on page 12 for more information).
1. Attach the supplied adapter plate to the 4S box with two 8-32 x 0.75-inch Phillips flat head screws
(supplied).
2. Pull the video and power wires to the ceiling tile.
3. Connect the video cable and wires:
• BNC: Connect the BNC connector from the unit to a mating BNC connector.
• UTP: Connect the blue wire to Video +; connect the gray wire to Video -.
4. Connect the power wires (refer to Table E).
AC operation only: If you are wiring more than one Camclosure to the same transformer, connect one
side of the transformer to the red wire on all units; connect the other side of the transformer to the
black wire on all units.
NOTE: Failure to connect all AC powered units the same way will cause the cameras to be out of
phase with each other, which may produce a vertical roll when switching between cameras.
5. Attach the back box to the adapter plate with four 8-32 x 0.375-inch Phillips flat head screws
(supplied).
