Installation
You can install the IS90 Series Camclosure integrated camera system as follows:
• Mount to the surface of a ceiling/wall (refer to Surface Installation: Ceiling/Wall on page10).
• Install in a suspended ceiling (refer to In-Ceiling Installation: Suspended Ceiling on page12).
• Install in a fixed ceiling/wall (refer to In-Ceiling Installation: Fixed Ceiling/Wall on page14).
• Mount to the surface of a 4S standard electrical box (refer to Surface Installation: 4S Standard
Electrical Box on page15).
• Install in a 4S deep electrical box (refer to In-Ceiling Installation: 4S Deep Electrical Box on page16).

UNSHIELDED TWISTED PAIR (UTP) VIDEO

The IS90 Series offers support for unshielded twisted pair (UTP). The UTP video output signal is
1Vp-p differential into a 100-ohm load. At a minimum, UTP requires Cat5, 100-ohm twisted pair cable.

SURFACE INSTALLATION: CEILING/WALL

1. Using the supplied template, mark the holes on the ceiling/wall for mounting the camera system
and for installing the wiring, and then drill the holes (refer to Figure3 and Figure 4 on page 11).
2. Pull the video and power wires through the ceiling/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 TableA).
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 (not supplied) to attach the surface mount ring
and back box to the mounting surface (refer to Figure3 on page 11). For a concrete ceiling/wall, use
8-32 mounting hardware (not supplied; refer to Figure4 on page 11).
