1.VIS-CAM System Installation Manual
1 Introduction
1.1 Document Overview
This document describes the steps necessary to deploy an installation of the JAI Vehicle Imaging
Subsystem, described as VIS from this point forward.
This manual also contains information about maintenance, troubleshooting and RMA (Return
Material Authorization) procedures.
JAI strongly recommends that the installer read this manual thoroughly, in order to obtain sufficient
knowledge about the VIS equipment, before initiating the actual installation.
1.2 Product overview
The JAI VIS consists of the following components:
• TLS-300 Traffic light sensor.
• The VIS Camera, comprised of an EN- camera with zoom-lens or fixed focal length lens, and an
anti-glare filter, a weatherproof housing with sun shield, heater resistors, interconnection PCB,
and a pan-tilt-roll mounting bracket.
• TNF-31 Flash unit or optional TNC-60 permanent illumination.
• VJP-300 EN-Junction panel with terminal blocks and RJ-45 connectors
and embedded diagnostics Features
• RS485-to-Ethernet Converter
• System interconnection cables
• Optional gigabit Ethernet switch
• Optional 24V DC Power Supply

• ENSetup Program
• Installation Documentation
Introduction 1
VIS-CAM System
Figure 1. VIS elements
1.3 System Components description
1.3.1 Traffic Light Sensor – TLS300
The JAI traffic light sensor is the driver of the VIS control network. It controls video signal
parameters of each camera to ensure high contrast images of passing vehicles and their license
plates, regardless of vehicle speed, weather or ambient light conditions.
Under the clear plastic dome of the traffic light sensor are mounted, in opposing directions, two
vertical plates and corresponding light collection staffs that protrude above a flat black base plate.
The sensor measures the ambient light reflecting off the face of both vertical plates. The design is
such that when the face of one plate is in direct sun, the other one is in shadow. These two
measurements identify the range of light levels that the camera is required to image without
saturation when a vehicle and its license plate are in the camera’s field of view (FOV). To ensure
correct functionality of the TLS-300, it is very important to ensure during installation, that the
sensor’s base plate is levelled with the road surface, and that the orientation of the sensor is
rotated so that the direction from the vertical plate A to vertical plate B is the same as the
direction of the traffic flow being observed by the traffic camera (see Figure 2).
2 Preparing for Installation
VIS-CAM System
Figure 2. Back shot VIS installation.
The TLS-300 light sensor is an essential component that ensures the VIS cameras will be ready to
capture high quality images of any vehicle and its license plate in virtually all weather and light
conditions.
It is very important to ensure that sensor positioning closely resembles real road conditions where
the vehicle image is most likely to be captured.
The light sensor is connected by means of the J-Panel VJP-300 and an RS485-to-Ethernet converter
to the Ethernet switch.
1.3.2 VISCAM
The VISCAM uses a state-of-the-art progressive interline transfer CCD that captures all of the
vertical resolution at once, thereby eliminating field-to-field imaging delays. The use of progressive
scanning allows the camera to freeze the motion of a rapidly moving vehicle at high resolution.
The VISCAM 300 houses a JAI TS-9720EN, the VISCAM 350 houses a JAI TS-1327EN, and the VISCAM
400 houses the TS-2030EN Ethernet camera with a built in IBM Power PC using an embedded Linux
O/S and 64Mb memory for various operations, such as frame store, JPEG compression, vehicle
fingerprint extraction, license plate find, running applications, and so on.
When the TLS-300 Traffic Light Sensor is used to control the VISCAM exposure settings, no moving
parts (such as an auto-iris lens) are included in the VIS system. This helps ensure high reliability for
the system.
A 12.5 mm to 75 mm manual zoom lens is provided as a standard with the VISCAM 300. This allows
the VISCAM to be mounted in a wide range of positions while ensuring sufficient resolution on the
vehicle license plates. A 35 mm fixed focal length lens is provided standard with the VISCAM 400. A
zoom lens is also available as an option. An anti-glare polarizing filter is mounted in front of the lens
to reduce smear in the picture caused by sun glints.

VIS-CAM System
1.3.3 Illumination
1.3.3 (a) TNF-31 Flash
The TNF-31 Flash generates light in wavelengths that are invisible to the human eye, but visible to
the camera. This makes the flash suitable for illuminating both oncoming and receding views of
traffic. Unlike near-infrared illuminators, the TNF-31 yields high contrast images of license plates
even if they have red characters on white or yellow backgrounds.
The TNF-31 Flash is automatically enabled whenever the TLS-300 Light Sensor determines that
ambient light is insufficient to produce a picture of usable quality. When the TNF-31 is enabled, it
fires every time the vehicle detector triggers the camera.
1.3.3 (b) White light LED.
JAI offers White LEDs mounted inside the camera enclosure. This option is usually employed when
certain rare color combinations on license plates do not yield sufficient contrast with the TNF-31
Flash option alone.
1.3.4 VJP-300 Junction Panel.
The VIS J-Panel is the central connection point for the VIS components. The J-Panel is a DIN-Rail
mounted PCB equipped with various interface terminals for interconnection of the VIS components;
this can be Ethernet connection, serial connection, TTL trigger feed and power supply. It offers the
possibility of manually selecting trigger polarity to the camera. Furthermore the J-Panel is equipped
with status LED’s and trigger switches for diagnostics and troubleshooting purposes.
1.3.5 RS485 Device Server.
The MOXA RS485 Device Server enables connection of RS485 serial devices to the Ethernet. The
purpose for the MOXA RS485 Device Server in the VIS system is to convert Ethernet to RS485
communication for the TLS-300 Light Sensor.
1.3.6 ENSetup Program.
The ENSetup Program is an Ethernet based software tool specifically designed to assist the installer
with VIS installation, and EN-Camera configuration and diagnostics. The program runs on a standard
PC / Laptop with Windows XP installed. Refer to Section 4 on page 31 of this manual and the VISCAM
300/400 EN Setup Manual for details.
1.4 Operational Overview.
During installation, the VISCAM and the optional light source are aimed at the area of the road
where vehicles and their license plates are most likely to pass through. The Traffic Light Sensor
continually registers the ambient light. The camera uses this information to set up exposure
variables to ensure an optimal image of the vehicle and license plate. During transition from day to
night the camera enables the optional TNF-31 Flash and/or white light LED’s to secure adequate
image quality during low ambient light conditions.
1.4.1 Trigger Mode
• A vehicle passes by a vehicle detector, sending a trigger to the VIS.
• The VIS employs a trigger to snap a video image of the vehicle and license plate when they are
optimally positioned in the camera field of view.
• The optional flash, if used, fires simultaneously with the camera to ensure correct exposure for
the image if the ambient lightning is too low.

2.1 Installation Preparation
To prepare for installation, consider the fundamental requirements for an effective deployment of
the Vehicle Imaging Subsystem. There are two basic ways to position the camera: over the lane or
beside the lane. Figure 3 and Figure 4 depict a typical over-lane installation. Figure 7 and Figure 8
on page 13 depict a typical beside-lane camera installation.
2.1.1 Over Lane Positioning
Over lane camera mounting is always employed when the road width being monitored contains more
than two lanes of traffic, when a convenient overhead structure is already in place, or when
preventing vandalism is a paramount concern.
The VIS’s varifocal (zoom) lens is adjusted during installation to create 135 pixels across a 1
foot wide license plate (standard for US style of plates, may differ by region) placed 2 feet
above the ground level at the nominal trigger position (loop or light curtain, etc.). This
resolution maximizes license plate reader, vehicl e matcher, or other image processing
techniques performance. The highest performan ce from the subsystem is achieved when the
variation in plate size is kept to within ± 5% which typically means that the vehicle trigger
accuracy should be within ± 1 foot (@ trigger plane defined by client.) at all speeds. Low
latency vehicle triggering is very important and should not be overlooked. Please contact JAI
for support on this issue.

Figure 4. Typical Over Lane Site Layout Plan.
2.1.1 (a) Camera tilt considerations
The requirement to freeze the motion of high-speed vehicles limits how steep or shallow the tilt
angle of the camera may be. For example, it is important to prevent the horizon from appearing in
the image, and thereby allowing the sun to blind the camera. For over lane installations, a camera
tilt between 20° to 30° is recommended–with 25° being considered the optimal angle. This angle of
tilt is the best compromise between minimizing visibility blockages caused by closely spaced
vehicles and maximizing plate visibility for plate mounts that are slightly recessed or tilted
downwards.
2.1.1 (b) Asynchronous triggering considerations
When the VIS is operated in trigger mode, a vehicle detector is employed to cause the camera to
capture an image at the precise moment the vehicle is in the best position to image both the
vehicle and its license plate. The delay between the time the vehicle passes the trigger position on
the road and when the trigger signal actually reaches the VIS must be kept to a minimum to prevent
high-speed vehicles from moving out of the area viewed by the camera before the image is snapped.
2.1.1 (c) Camera height versus trigger distance considerations
It is critically important, to select the correct distance between the camera and the location on the
road where the camera is triggered to capture an image. Minimizing the cost of installation is
usually also an important concern. This means that whenever possible, it is best to use existing
structures or previously installed elements. The following charts (Figure 5 and Figure 6) provide a
wide range of trade-offs between camera height and trigger distance to enable the installer to
select convenient camera and light sensor locations relative to existing mounting structures and
vehicle trigger locations. Adhering to the installation options provided in the installation charts,
yields camera images that are generally suitable for automatic license plate readers (ALPR).
To use the charts correctly, please follow the steps below.
1. First measure the height above the road to convenient camera mounting locations.
2. Measure the distance along the road from directly beneath each candidate camera position to
convenient trigger locations.

3. Select the appropriate installation chart for either USA or European style license plates. To
obtain charts for license plates from other countries, please contact the JAI ITS division directly
at (+1) 408 7470 300 – 102.
4. Plot the candidate camera-height / trigger-distance pairs on the chart and determine if the
selected location lies within the wedge of recommended values.
5. If several locations are suitable, choose the one that yields the greatest overall slant range
between camera and trigger location.
The standard VISCAM unit is equipped with a 25 – 75 mm zoom lens. This lens provides the full range
of camera height and trigger distance listed in the installation charts.

structue.
Generally the flash head must be separated from the camera by a radial distance of at least three
and a half feet (1.2 meters).
If the flash is positioned closer to the camera, reflections from the license plate will cause
overexposure.
If possible, position the flash head in level with the reference plane shown in Figure 9. This plane is
in level with the top surface of the camera enclosure, but slices through the center of the lens.

3 Installing the Vehicle Imaging System
The individual components of the system is electrically linked together as shown in Figure 1, “VIS
elements,” on page 2. The VIS CAM 300/400 camera has connections to the J-Panel and an optional
Flash, Night Light and Laser Vehicle Detector. The J-Panel has connection to two VIS CAM 300/400
cameras, one Traffic Light Sensor, a 24V Power Supply, a Lane Controller, a RS485-to-ethernet
converter for the light sensor signals, Trigger input, an optionally second J-Panel and finally a
gigabit Ethernet switch.
3.1 Installing the TNF-300 Traffic Light Sensor.
When installing the Traffic Light Sensor ensure the unit is positioned higher than either the camera
or the flash unit so the A-side is in direct sun whenever the targeted vehicles license plates are. See
Section 2.1 on page 6 for general site layout guidelines.
It is extremely important the light sensor be properly positioned at the site. The light sensor must
be placed so that no shadows from surrounding structures are cast on side A when the license plates
being imaged by the VISCAM are in direct sunlight.
Because sun angles at any given site can change according to time of day and time of year, it is
important to verify that the proposed setup will function on the actual spot.
3.1.1 To install the Traffic Light Sensor:
1. Disconnect Power
2. Loosen the four hex screws and remove the flange from the mounting base. See Figure 10.
