Introduction PowerDome Installation Manual
1 INTRODUCTION
This manual provides step-by-step installation instructions for all PowerDome cameras, housings and
accessories.
1.1 DESCRIPTION
A PowerDome is a variable speed PTZ (pan/tilt/zoom) dome camera used in CCTV systems for discreet
surveillance of a remote area. A PowerDome’s operational features are customized and stored within its
own on-board programmable nonvolatile memory. PowerDomes are programmed using Vista
NPX/R/KDB/J3De or VPD-KBD controller keypads.
1.2 OPERATION REQUIREMENTS
The PowerDome has three built-in receivers, two for RS485, PowerDome, and Pelco D, and one for
coaxial UTC control. The dome automatically detects the current protocol. UTC control requires a Vista
Triplex Columbus hard disk recorder and a minimum of one keyboard. See Figure 1. A minimum of one
keyboard is required for RS485 control. See Figure 2.
Note: This manual does not cover Pelco D control.

Keypad (RS485 control) PowerDome
Figure 2. Basic application with RS485 control
1.3 CABLE REQUIREMENTS
For RS485 operation, PowerDomes require video, power, and data cables.
The video cable carries the video signal to the remote viewing site. If sending video via coaxial
cable, a 75 Ω coaxial cable is typically used. If sending video via twisted-pair cable, use an
unshielded, CAT5 twisted-pair cable.
6 1040647A / July 2003
PowerDome Installation Manual Introduction
The 24VAC cable powers the PowerDome and the camera. To determine cable size, refer to the
Power Cable Size and Length subsection of the Introduction.
The RS485 control cable carries commands from the keypad to the PowerDome. An RS485
compatible shielded, two-conductor, twisted-pair cable is required. Recommended cable size is 22
gauge (0.64 mm).
Note: When using the UTP interface modules Vista recommends that you use only active receivers.
For UTC control, only a video coaxial cable is required.
1.4 POWER REQUIREMENTS
CAUTION:
For optimal video performance, all PowerDomes must be powered from an isolated 24 VAC power
source—fused outputs are not adequate. Allowable voltage range is 20 to 28 V.
All domes require a 24 VAC power supply that provides isolated outputs to operate the domes’ pan/tilt
drive, camera, and heater/fan (if applicable). The total power requirement varies depending on the model
of the PowerDome.
Dome power requirements (at 24 VAC):
All domes without a heater/fan require 20 VA
7 inch domes with heater/fan require 55 VA
1.5 POWER CABLE SIZE AND LENGTH
It is important to choose the proper gauge of the cable that supplies 24 V to the PowerDome. An
inadequate gauge will cause a voltage drop resulting in improper operation.
Table 1 gives the recommended cable lengths of varying wire gauges for a PowerDome with a colour
camera. Note that the heater and fan reduces maximum cable length substantially.

Housing Installation PowerDome Installation Manual
2 HOUSING INSTALLATION
A complete PowerDome consists of an upper housing, a
pan/tilt assembly with a built-in receiver and camera, and
an acrylic dome. See Figure 3.
Upper housing
Pan/tilt assembly
Dome
Figure 3. PowerDome components
In General: The method of installation depends on
which upper housing is being used. Installation involves
securing the upper housing, making cable connections,
mounting the pan/tilt assembly, and fastening the acrylic
dome.
The Interface Module: Make all PowerDome cable
connections (video, RS485, and 24 VAC) to an interface
module. There are two types of interface modules: one is
for coaxial video, and the other is for UTP video
transmission. When you send video via coaxial cable,
make the connections to a coaxial interface module.
When you send video via unshielded twisted-pair (UTP)
cable, make connections to a UTP interface module.
Note: Vista recommends that you use only active receivers with the UTP interface modules.
CAUTION:
For safety reasons, all mechanical components used to support the PowerDome 6 inch flush-mount and
7 inch pendant-mount assembly must be able to support a 16 kg (35 lb) load.
There are separate sections for the installation procedures for each housing style.
