1.0 GENERAL DESCRIPTION

The 3940 iDome series is an integrated camera/
positioner unit that combines a high performance
digital signal processing camera, pan-and-tilt, and
control receiver for communications into one inte­grated package (figure 1). The 3940 is available in
two basic versions:

Analog Version: The Model 394x-x1xx has
NTSC video output and control functions are han­dled by RS-422. Firmware changes can be upload­ed via an Ethernet connection

IP Version: The Model 394x-x9xx communi

­cates via Ethernet and supplies video via Ethernet
IP video packets. On this IP version RS-422 is not
used. An IP dome is configured to connect to a hub.
Connecting it directly to a computer will require use
of a crossover cable or adapter.

Throughout this manual the entire assembly will
typically be referred to as the “iDome” or just the
“Dome.”

There will also be references to the “Analog”
version and the “IP” version when this distinction is
important.

Specifications are contained in table 1 and a
model number interpretation diagram is provided in
figure 2. This diagram can be used to interpret an
existing model number.

1.1 ELECTRICAL CHARACTERISTICS

The camera uses digital signal processing. It has
an internal source ID generator. Integration control
plus a built-in video storage card provides full color
continuous video even at very low light levels.

standard pan-preset or manual control, the iDome
can move with a pan speed of 250° per second.

This iDome will operate in temperature ranges
from -34° to +74° C and with winds of up to 90 mph.
The enclosure protects against salt, grime, dirt, and
moisture.

The integrated receiver/driver, contained within
the iDome, communicates using Cohu protocol
messages and will also control the digital DSP
camera functions. All iDome functions are operable
via either RS-422 or Ethernet serial communications
depending on the version.

In case of power failure, all 64 preset positions
are stored in nonvolatile memory.

Each iDome “address” within a surveillance sys­tem can be selected electronically from the Monitor­ing Center. There are no mechanical dip switches
to set at the camera, and each unit responds to the
central command only if addressed. This provides
greater integration flexibility for the designer and
more dynamic camera control for the operator.

Privacy zones can be set up using polygon
shaped windows drawn with the Viewer/Gui soft
ware. These blanking windows are generated elec

-

­tronically within the digital signal processing (DSP)
and provide positive control of such areas.

Electronic image stabalization (EIS) is available
for one version of the two 23X camera modules and
it is a standard feature for the 35X camera module.
This EIS feature helps to minimize the effects of
slight vibrations on a Dome in certain mounting situ­ations — such as when it is mounted on a tall pole.

1.1.1 Control Software

The iDome speeds are variable with maximums
of 250° per second for pan and tilt. Pan range is
a continuous 360 degrees while the tilt range is 0
to 90 degrees from the horizontal with auto-flip at
the 90° point. There are 64 preset positions with a
preset accuracy of 0.1 degree. When responding to

6X-1070

The analog and the IP versions of this Dome
each require different software to control them and
to view their video. Separate manuals cover these
Viewers. Refer to Cohu manual part number 6X­1071 for the IP viewer/GUI manual and part number
6X-1072 for the analog viewer/GUI manual.

1.2 MECHANICAL CHARACTERISTICS

Although the iDome is a single mechanical as­sembly for installation purposes, it actually consists
of two primary subassemblies inside the dome: (1)
the camera and (2) the positioner.

All camera circuits are contained within a sealed
and pressurized environmental dome housing hav­ing either a clear or smoked window through which
the camera lens views outside scenes. This dome
is fully covered by a sun shield spaced slightly away
from the housing itself. This minimizes heat buildup
due to sunlight. Vent holes at the top of the dome
must be kept clear to maintain air flow.

The iDome is a sealed and pressurized (dry
nitrogen) unit intended for indoor or outdoor use
under rain, snow, and other typical harsh weather
conditions.

Communications circuits contained within the
iDome are also protected from outdoor weather
conditions.

INSTALLATION

Table 2. Basic Mounting Arrangements

A sealing type MS connector is used on the
housing and when mated with a similar MS type
cable connector a good environmental seal is pro­vided for the mating pins and sockets.

A single multiconductor cable is routed to the
iDome location and then passed through the mount­ing pendant to provide for all signal, video, and op­erating power connections. Pin functions and layout
are shown in figure 22.

2.0 INSTALLATION

This section of the manual provides general
instructions about installation of the iDome using
various mounting arrangements.

The actual installation should be performed by a
qualified installation professional familiar with all the
local requirements for proper installation.

Figure 4. Basic Mounting

6X-1070

Configurations

Always preplan the installation to be sure that all
required cabling and address assignments are com­pleted. It may also be important to know the orienta­tion of the iDome when it is mounted at its location.
The Schrader valve (figure 23) should be accessible
for adding dry nitrogen if necessary.

The model number label indicated a mechani­cal home reference for all iDomes. Electrical home
for panning is 90° clockwise from this position as
viewed from above.

Table 2 lists the three basic mounting arrange

­ments. That pendant version consists of only the
iDome itself. The wall mount version of an iDome is
shipped with the wall mount arm. The pole mount
version is shipped with both the wall mount arm and
a pole mount bracket to which the wall mount arm
attaches.

Section 5 of this manual covers receiving inspec­tion, packing and return requirements for a return to
the factory, and static discharge protections. Static
should mainly be of concern when working inside a
unit, and this manual does not cover disassembly of
the Dome.

INSTALLATION

WARNING

One versions of the iDome operate from voltages
that can be dangerous: model 3945 (115 V ac). Use
all appropriate care when installing and maintaining
this version of the iDome.

2.1 INSTALLATION INTRODUCTION

This section is a brief overview of the various
mounting types. The installation methods described
in this manual are a general overview of typical in­stallations. Since the particular conditions at various
installation sites can vary widely, it is best if the ac

­tual installation is performed only by a professional
installer familiar with all local requirements.

2.1.1 Basic Mounting Configurations

An iDome can typically be mounted in any one of

three mechanical configurations (figure 4):

2.1.1.1 Pendant Mount

The basic configuration. The iDome hangs di­rectly from a supplied 1.5-inch female NPT (national
pipe thread) support. This support must provide
for the connector of a multiconductor cable to pass
down through the 1.5-inch pipe nipple for mating
with the iDome.

2.1.1.2. Wall Mount

This mounting arrangement requires an arm that
bolts to the wall. The iDome hangs from the end of
this arm.

2.1.1.3. Pole Mount

This mounting arrangement is similar to the Wall
Mount — except that the mounting arm attaches to
a bracket fastened to a pole instead of directly bolt­ing to a wall.
