Cover and Back Box Installation
The IS150 Series Camclosure integrated camera system mounts only into a wall or ceiling.
UNSHIELDED TWISTED PAIR (UTP) VIDEO
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.
FIXED CEILING/WALL
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/wall. Use the supplied adapter plate as
a template.
2. Pull video and power wires through the ceiling/wall.
3. Connect the video cable/wires:
• BNC: Connect the BNC connector from the unit to a mating BNC connector.
• UTP: Blue wire = Video +
Gray wire = Video -
4. Connect the power wires.
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 and may produce a vertical roll when switching between cameras.
5. For a non-concrete 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.
