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. Pull the video and power wires to the ceiling tile.

2. Mount the unit to the ceiling tile (refer to Figure 3):

a.

Remove the ceiling tile from the ceiling.

b.

Cut a hole 3.5 inches (9 cm) in diameter in the ceiling tile. Use the adapter plate (supplied) as 
a template. Punch four screw holes in the ceiling tile.

c.

Attach the back box to the ceiling tile and adapter plate with four 8-32 x 1.25-inch Phillips flat 
head screws (supplied).

d.

Reinstall the ceiling tile with the unit.

Figure 3. Ceiling Tile Installation

3. Remove an adjacent ceiling tile.

4. 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 -.

5. Connect the power wires (refer to Table D).

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.
