About the Outdoor Housing
The ADODH outdoor housing (Figure 1) is used to
attach the DeltaDome programmable surveillance
camera to an outdoor mounting structure.
Note: This guide assumes that a mounting
structure is in place and that data and power
cables have been pulled to the installation site.
Data Cable Requirements
Table 1 shows data cable requirements for
SensorNet, RS422, and Manchester networks. For
more information about communication protocols
and cable networks, see Communication Protocols
and Cable Networks, 8000-2573-19.

Power, data, and video cables can be ordered
separately or within a composite cable that can be
ordered in various lengths. All cables must be
plenum rated for indoor installations where cable is
routed above the ceiling. Order parts through your
distribution network.
Note: If you order cable from an outside source,
wire colors may be different.
** Belden 88760 (plenum), or Belden 8760 cable (non-
plenum) cable is recommended. Plenum-rated cable
is required for indoor installations where cable is
routed above the ceiling. Order cable directly from
Belden by calling 1-800-235-3361.

Power Cable Requirements
Length of power cable between a Class 2 LPS (low
voltage) ac source, such as a J-box, and the dome
depends on the ac line voltage. See Table 2 below
for cable lengths based on worst case low line
voltages for Japan (100Vac), North America
(120vac), and Europe (240vac).

Power-Up Routine
After power is connected to the dome, the dome
performs the following homing routine.
1. After a few seconds, the camera lens tilts up
into the housing and eyeball assembly.
2. The lens tilts downs until it looks at the floor.
3. Eyeball pans slowly.
4. Lens tilts up 90° (home position).
Once the lens is in its home position, you can
then use the controller to call up the camera
and control it.
Synchronizing Domes
To prevent picture rolling when switching from
camera to camera, all domes can be synchronized
to a 50Hz or 60Hz ac source. A V-phase adjust-
ment at the control console enables the dome to
sync to any line phase.
