The IS150 Series Camclosure integrated camera system mounts only into a wall or ceiling.

The IS150 Series offers support for unshielded twisted pair (UTP). The UTP video output signal is 1 Vp-p 
differential into a 100-ohm load. At a minimum, UTP requires Cat5, 100-ohm twisted pair cable.

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. Cut a hole 3.5 inches (9 cm) in diameter in the ceiling or wall. Use the adapter plate (supplied) as 

a template.

2. Pull the video and power wires through the ceiling or wall.

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 C).

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. For a nonconcrete ceiling/wall, use 6-32 toggle bolts to attach the surface mount ring and back box 

to the mounting surface. For a concrete ceiling/wall, use 8-32 mounting hardware. Mounting 
hardware is not supplied.
