System Overview

The AD32 System is an economical video security

management system. This matrix-switched CCTV

(closed circuit television) surveillance system is capable

of controlling up to 32 video inputs (SpeedDome

cameras) and up to five video outputs (video

monitors/VCRs). The system’s operator uses video

control stations (Enhanced T

OUCH TRACKER controllers

to program and control the cameras. Only SpeedDome-

type cameras can be programmed.

The AD32 System (Figure 1-1) consists of a Video

Matrix Switcher (VMS), 1 to 5 video monitors/VCRs, 1

to 32 video cameras, and 1 or 2 T

OUCH TRACKER

controllers. Each SpeedDome provides four alarm inputs

and four switched outputs. The AD32 VMS provides

video switching, 8 alarm inputs, 1 relay output, text-

overlaid camera titles, and timed events. SensorNet, a 2-

wire communications protocol, provides the data path

for passing control information between the system

components. This information originates at the T

OUCH

TRACKER controllers, passes through the EIMs, and

along the SensorNet cable to the attached domes, J-

boxes, and VMS. Video data from each dome connects

directly to the VMS via a dedicated coaxial cable.

The user operates the AD32 System through the primary

or optional secondary T

OUCH TRACKER controller. The

controllers provide the user interface, control logic, and

dome buffer storage. The primary T

OUCH TRACKER is

responsible for SensorNet polling and alarm processing.

Both T

OUCH TRACKERs connect to the VMS through its

RS232 ports.

System Components

This section describes the major components of the

AD32 System.

SpeedDome and SpeedDome Ultra

The SpeedDome and SpeedDome Ultra camera domes

are part of a programmable camera network. These

devices let security personnel remotely track a target,

near or far, even in low light. The domes, which are

small and unobtrusive, are designed for use in retail

stores, casinos, manufacturing facilities, hotels,

hospitals, and locations where appearance is important.

Video Matrix Switcher

The Video Matrix Switcher (VMS) provides switching

of all cameras to all monitors. The heart of the system is

a full cross-point video matrix switch. Switching is

performed in response to operator requests from the

T

OUCH TRACKER controllers or by automatic action by

preprogrammed sequences, alarms, or timed events. The

VMS also provides the system’s time and date clock, an

event timer, and stores the camera title text.

External Interconnect Module (EIM)

This is an interconnect junction that lets the TOUCH

TRACKER controllers operate from a single cable. The

EIM’s DB9 connector provides a standard RS232

connection to the VMS.

Video Monitor

The system supports up to five monochrome or color

monitors.

Enhanced TOUCH TRACKER Controller

The Enhanced TOUCH TRACKER Controller (Figure 1-2)

is the main input control interface for the AD32 System.

The T

OUCH TRACKER receives input from the operator

through its keypad, Tracker Ball, and zoom and focus

buttons. Each T

OUCH TRACKER provides audio-visual

outputs such as beeps and messages. The messages are

displayed on the T

OUCH TRACKER’s LCD screen.

The Tracker Ball provides variable speed control of a

camera’s pan and tilt.

Zoom and focus buttons let you control a camera’s zoom

and focus.

The keypad lets you select video from individual

cameras and control their pre-programmed movement. It

also provides iris control, auxiliary control, monitor

selection, and clear alarms.

The LCD screen displays status information, the

selected camera and monitor numbers, numbers entered

from the keypad, and system prompts and messages.

Introduction

This chapter describes how to install and configure the

AD32 System.

The design team determines the SensorNet network

topology (daisy-chain, backbone, or star) and how

devices will attach to the network. These decisions

determine the SensorNet data cable routing between the

SensorNet devices and the AD32 Video Matrix

Switcher (VMS), and which devices require

termination. One- and six-position SensorNet J-Boxes

(if required) are available, providing power for one or

six domes, respectively. Additional domes can be

attached to either model, but each dome must be

externally powered.

AD32 SYSTEM

Planning the Installation

After completing the system design and ordering the

required components, your first step in installing a

AD32 System is to develop a detailed system layout.

This results in a marked-up facility floor plan showing

the precise locations of all domes and cameras,

monitors, VCRs, T

OUCH TRACKER controllers, and the

AD32 VMS.

After you have a count of the number of devices that

will be attached, you need to design the SensorNet

network. See the sections SensorNet Network Design

Guidelines and Designing the SensorNet Network.

After completing the network design, mark on the floor

plan the location of all J-Boxes (if required) and show

cable routing to connect cameras, domes, J-Boxes, and

AD32 System components. When you complete the

floor plan, tour the facility again to note any special

considerations, such as plenum ceilings, fire walls,

physical barriers, etc. that could affect component

placement, cable routing, or other installation activities.

To provide flexibility for future dome expansion,

leave one connector unused in each J-Box.

After deciding on component placement and cable

routing, measure and order the required cables. If

schedules permit, order cables to arrive one to two

weeks before the AD32 System components, so you can

run them before the AD32 installation.

You can order pre-cut cables for most

requirements. Always use this capability instead of

cutting bulk cable to length at the customer's site.

For guidance on measuring, specifying, and

ordering cables, see the SensorVision Cable Survey

and Ordering Instructions (8000-1526-01).

Also specify the electrical service requirements and

recommend its installation be completed before delivery

of the AD32 System components. Here are some

general planning guidelines.

1. Each J-Box requires an electrical outlet.

2. SpeedDome and SpeedDome Ultra can receive

power through the composite cable from the J-Box.

If not connected to a J-Box, each dome requires a

transformer or a power cable from a central source.

3. Each fixed camera requires electrical power. This

can be supplied by a local transformer or by a

power cable from a central source.

4. Electrical outlets are required at the AD32 location

for the VMS, each monitor, each VCR, and each

EIM transformer or power supply.

5. When using outlet-mounted transformers, note that

many require a mounting space greater than one

outlet. Specify outlet spacing and quantities to

accommodate this requirement.

When the first cables or equipment arrives, meet with

the Facility and Loss Prevention Managers to review the

layout and installation plans. This will ensure everyone

is in agreement with the installation activities that

follow.

SensorNet Network Design

Guidelines

Understanding the SensorNet network is very important

for a successful installation. This understanding will

help you and the site manager plan an efficient, reliable,

and flexible network that will meet the long-term needs

of the facility. This section provides basic guidelines for

selecting a suitable topology and installing the network

devices.

Distances and device counts in this section assume

AWG24 or 22 unshielded twisted-pair cable.

Shielding adds capacitance, causing the SensorNet

signal level to decline more rapidly as devices are

attached or cable length increased.

SensorNet devices will operate satisfactorily at

signal levels between 5V and 1V (differential peak-

to-peak, measured with a scope). A SensorNet J-

Box can be attached as the signal reaches 1-2V, to

amplify the signal back to 5V. This will extend the

network's distance and allow additional devices to

be added.

Network Design Considerations

A SensorNet network consists of one or more network

"links". Each link includes a twisted-pair cable, a

SensorNet driver, and one to 32 SensorNet devices. A

SensorNet link's maximum cable length is 1km (3,281

ft). Devices can attach anywhere along the cable.

For proper operation, you must terminate both ends of

each SensorNet link. This prevents signals reaching the

end of the line from being echoed or reflected back

along the line. All SensorNet devices and drivers have a

termination switch or jumper for this purpose. When in
