Product Overview
The SpeedDome LT camera dome (Figure Chapter 1-1)
is part of a programmable network of camouflaged cam-
eras. These devices enable security personnel, from a
remote console, to track programmed targets (presets),
near or far, even in low light. Small and unobtrusive, the
dome can be used in facilities such as retail stores,
casinos, manufacturing facilities, hotels, and hospitals,
especially where appearance is important.
Main Components
The dome consists of the following assemblies:
•Carriage assembly. This assembly mounts directly
into the housing. The carriage assembly contains the
dome’s power supply and pan motor; the power
supply provides regulated dc power to the eyeball
assembly. The Unicard PC board is the interface
between the dome and the console and receives all
video, ac, and data. This board also provides the
dome address and transient protection and is the
central controller for all dome functions, controlling
360° pan movement and storing targets and patterns.
An LED indicator on the Unicard enables the
installer to verify when power and data are available.
•Eyeball assembly. This assembly fits into the
carriage assembly and contains the dome’s tilt motor
and electronics used to operate the eyeball, storing
automatic camera patterns and directing camera
video to the composite cable via the Unicard. The
rotating eyeball, gloss black and 190cm (7.5”) in
diameter, houses the 1/4” CCD camera assembly. A
clear, acrylic “contact lens” mounts flush with the
contour of the eyeball to prevent detection of the
camera’s viewing position.
Camera Options
The dome, as shipped, contains one of four different
CCD cameras.
•Color NTSC (60Hz)
•Color PAL (50Hz)
•Monochrome EIA (60Hz)
•Monochrome CCIR (50Hz)
These cameras have 12X optical zoom with continuous
auto focus and backlight compensation. The color
camera is fully digital, has no field adjustments, and has
better light sensitivity and picture resolution (430 TV
lines) due to Digital Signal Processing (DSP).

Indoor Mounting Methods
The dome’s housing mounts directly to indoor hard or
tile ceilings using hardware supplied with the dome or
to one of several optional mounting structures. These
methods facilitate quick installation after site prep-
aration, enabling wiring to be done during rough
building construction.
Hard/Tile Ceiling Mounting
The dome’s housing can be surface mounted directly to
sheet rock ceilings, wood ceilings, or ceilings with spe-
cial finishes (Figure Chapter 1-3). The housing can also
be mounted in a section of tile ceiling using a ceiling T-
bar among other components (Figure Chapter 1-4).
Mounting hardware varies with the type of installation
kit.
Figure Chapter 1-3. Surface mounting to hard
ceilings
Figure Chapter 1-4. Surface mounting to tile
ceilings
Mounting Structures (Optional)
The dome’s chassis can be mounted to several indoor
ceiling mounting structures (Figure Chapter 1-5). These
structures are as follows:

Features
Performance Features
In alphabetical order:
•Apple Peel Default Pattern. Controller dependent,
the dome automatically defaults to an “apple peel”
pattern where, starting at the ceiling, the camera pans
the entire viewing area three times, dropping 30°
after each pan.
•Automatic Calibration. When power is first
applied, the dome calibrates its position-sensing
electronics by going through a one-minute motion
routine (during which it ignores commands). Once
calibrated, the dome is in its "home" position, ready
for use, with the lens pointing at wide angle along
the top of the ceiling. "Homing" does not occur
again unless power is removed.
•Automatic Lens Control (ALC). Also called auto-
iris, this feature enables the lens iris to adjust to
different lighting conditions automatically; however,
manual adjustments can be made at the console. See
Iris Preference in this section.
•Automatic/Manual Dome Reset. A watchdog
circuit automatically resets the dome if voltage levels
or preprogrammed instructions are incorrect. The
dome can be manually reset using keyboard
commands from the console.
•Auto-Pan. The dome can be taught to continuously
pan any designated area. Once activated, the pattern
repeats until interrupted.
•Automatic Synchronization. The dome automati-
cally synchronizes to a 50- or 60Hz ac source or
free-runs on its own internally generated clock.
•Continuous Rotation. The dome rotates 360°.
There are no end stops.
•DSP Motor Control. Digital signal processing
(DSP) and dynamic motor braking assure precise
and fluid camera movement and accuracy.
•Focus Preference™. Provides automatic focusing
with the benefits of manual override.
•High Resolution Cameras. The dome uses mono-
chrome and color cameras. These cameras have 12X
optical zoom with continuous auto focus and
backlight compensation.
•Iris Preference. Manual or automatic iris control
enables the operator, on a selective basis, to
manually fine-tune back lighting problems for proper
illumination of the subject.
•QuickView™. The dome can precisely pan, tilt,
zoom and focus in less than two seconds. This speed
and accuracy enables one SpeedDome LT to offer
better coverage than multiple fixed cameras.
•Switching Power Supply. This circuit reduces
power consumption and enables cable runs of up to
120 meters (394’).
•Transient Protection. All dome inputs and outputs
are opto-coupled, transformer isolated, or provided
with heavy duty transient protection to enhance long-
term product reliability.
•Zoom Adjusted Program (ZAP)™. This feature
automatically adjusts pan and tilt speeds during
manual operation to keep the video image constant
as the camera lens adjusts from wide angle to
telescopic. For example, a 12x lens panning at
100°/second at full telephoto slows to 0.5°/second at
full zoom.
•180° Flip. The dome can follow a target as it moves
toward the camera, directly beneath it, and away
from the camera by flipping its camera 180° at the
point where the target passes directly beneath the
dome.
•12x “Fast” Lens. A 4-48mm, f1.6 lens enables the
video image to fill the monitor screen at 15m (50’).

Installation & Service Features
In alphabetical order:
•Daisy-chaining. Control cables can be daisy-
chained from dome to dome (10 domes maximum
for RS422), using up to 914m (3000’) of cable.
(RS422 uses two, 22 AWG, individually shielded,
twisted pairs; SensorNet uses one 22 AWG twisted
pair without a shield.)
•Interchangeability. Each dome can be easily moved
to a new location.
•Internationally-recognized connectors. Compos-
ite and video cables from the controller connect to
the dome via internationally recognized screw-
terminal connectors. The dome address can be
changed without cable disconnect (powering down
the dome).
•Line lock. The dome can free-run on its own
internally-generated 2.5MHz signal, or to prevent
picture rolling on the monitor, be sync’d to a 50 and
60Hz ac source.
•Power and communications LEDs. On the dome’s
Unicard, green power and yellow communications
LEDs (same as on the J-Box) indicate that power
and data are reaching the dome.
•Remote manual dome reset. The dome can be
manually reset using keyboard commands from the
console.
•Safety. The camera dome meets all international
regulatory agency standards. Electrically, the dome
uses low-voltage Class 2 circuitry, and cable
connectors keyed to eliminate electrical hazards
during use. Indoor domes use safety chains to anchor
the dome to building structural members and a safety
lanyard to retain the chassis in its housing during
servicing.
•Snap-Hinge Chassis. Two sets of spring-loaded
locking pins enable the light-weight, camera chassis
to swing out of its housing for servicing or removal.
•Simple Disassembly. Only a Phillips screwdriver is
required to disassemble each motor (2 screws), the
slip ring (2 screws), the camera /bracket assembly (2
screws), and each pc board (3 to 4 screws). The
dome can be located up to 250m (820’) from the
junction box.
•V-Phase Adjustment. The dome has a remote V-
phase adjustment that enables synchronization to any
line phase by one person at the control console.
