VISCAM 1000 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. The core of this subsystem is a traffic optimized
series of camera systems. This manual will discuss specifically the VISCAM 1000 system. The system
combines an industry leading vehicle imaging camera with high performance triggering/light sensing and
LED illumination, all in a sleek, weatherproof housing.
This manual also contains information about maintenance and troubleshooting.
JAI strongly recommends that the installer reads this manual thoroughly, in order to obtain sufficient
knowledge about the VIS equipment, before initiating the actual installation.
1.2 Product Overview and System Hardware Components
Figure 1. VISCAM 1000 Installation Overview
VISCAM 1000 Systems

Introduction
1.2.1 VISCAM 1000 System
The VISCAM 1000 uses a state-of-the-art camera system that freezes the motion of a rapidly moving vehicle
at high resolution, a zoom-lens or fixed focal length lens, and an on-axis illuminator, a weatherproof
housing with sun shield, heater resistors, I/O board, and a pan-tilt-roll mounting bracket. See Figure 2.
The VISCAM 1000 (All-In-One) features an optional embedded JAI trigger/light sensor for image triggering
and image contrast control. It also features an optional embedded LED-1000 illuminator (infrared, white or
blue) for independent 24/7 operation and excellent license plate contrast.
1.2.2 External Traffic Light Sensor – TLS-301 (optional)
The JAI Traffic Light Sensor TLS-301 provides an option to using VISCAM 1000’s built-in light sensing
capabilities described in Section 4.10.3. The TLS-301 estimates vehicles’ license plate lighting conditions
and controls the exposure and gain parameters of each camera to ensure high contrast images of vehicles
traveling through the field of view and their license plates, regardless of vehicle speed, weather or
ambient light conditions. For more information about the TLS-301, see Appendix B at the end of this
document.
1.2.3 External Light Sources
JAI offers a full lineup of lighting solutions optimized for a large number of applications.
The TNF-35 Traffic Night Flash unit is a 17W, long-life flash with an effective life span of up to 4 million
flashes. It comes in various application specific configurations for emission spectrum. With the standard
filter it generates light in wavelengths that are invisible to the human eye, but visible to the camera. For
more information about the TNF-35, see Appendix C at the end of this document.
The TNL-50 is a newer, high-performance LED Flash intended for traffic applications, including automated
number plate reading systems. The TNL-50 is field proven to produce high-contrast images of passing
vehicles and their number plates. With its very high light output, versatility, ease of installation and its
compact size, it makes it easy to see why it is an industry leading illumination solution. It also comes in
three configurations, broadband white, NIR, and blue to support various applications. Additional
information about installing and configuring the TNL-50 can be found in Sections 3.3 and 4.7 of this
document.
Both the TNL-50 and TNF-35 are automatically enabled whenever the camera or the optional TLS-301 Light
Sensor determines that ambient light is insufficient to produce a picture of usable quality.
1.2.4 Embedded Light Sources (LED-1000 IR, white or blue)
Various applications require the use of an embedded illuminator. JAI offers the LED-1000 illuminator with
infrared, white, or blue LEDs. See Figure 2.
1.2.5 VJP-300 Junction Panel
The J-Panel is the central connection point for the VIS components. The J-Panel is a DIN-Rail mounted PCB
(printed circuit board) equipped with various interface terminals for interconnection. Each J-panel can
support up to two VISCAM systems.
1.2.6 Optional 24V DC Power Supply
JAI provides a robust industrial rated power supply.
1.2.7 Optional gigabit Ethernet switch
JAI recommends using a field-proven industrial rated gigabit Ethernet switch.
1.2.8 System interconnection cables
JAI supplies a cabling solution that has proven its reliability on a large number of installation sites.

1.3 VISCAM 1000 Product Line
The VISCAM 1000 houses a JAI TS(C)-5000EN camera. The EN camera series are Ethernet based with a built
in processor using an embedded Linux O/S for various operations, such as handling communication with
lane controller and back office, frame storage, JPEG compression, and so on. An optional external TLS-301
Traffic Light Sensor is available, as well as optional embedded LED-1000 illuminator.

2 Preparing for installation
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 configurations: overhead (over the lane) or side fire
(beside the lane). Figure 3 depicts a typical overhead configuration. Figure 4 depicts a typical side fire
configuration.
2.2 Overhead Positioning
Over lane camera mounting is always employed when the road width being monitored contains three or
more lanes of traffic, when a convenient overhead structure is already in place, or when preventing
vandalism is a paramount concern.
Figure 3. Typical Overhead Site Layout for a single lane
Installing the VIS 5
VISCAM 1000 Systems
(a) Single Lane or Dual lane considerations
Figure 3 shows a typical single lane configuration. However, with the VISCAM 1000’s higher 5Mpixel
resolution, it can now cover up to two lanes of traffic.
The VISCAM 1000’s varifocal (zoom) lens is adjusted during installation to create the following conditions:
Standard for US style of plates: 135 pixels across a 1 foot wide license plate placed 2 feet above the ground
level at the nominal trigger position (ground loop, etc.). With typical US lane coverage (14’), the VISCAM
1000 will yield ~180 pixels/plate. If maintaining the 135 pixels per plate, the lane coverage is now 18’.
Standard for European style of plates: 140 pixels across a 50 cm wide license plate placed 60 cm above the
ground level at the nominal trigger position (ground loop, etc.). The coverage is now up to 9 meters, which
can definitely cover two lanes.
(Note: this can differ for other regions or plate styles.) See Section 4 for set up instructions. This resolution
maximizes license plate reader, vehicle matcher, or other image processing techniques performance. The
highest performance 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/30 cm (@ 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 if needed.
(b) 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.
(b) Asynchronous triggering considerations
An embedded 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. If an external
triggering device is used (i.e. ground loop) the delay between the time the vehicle passes the trigger
position on the road and when the trigger signal actually reaches the VISCAM 1000 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.
(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. Contact JAI for support on setting/validating site geometry.

If the flash is positioned closer to the camera, reflections from retro-reflective license plates will likely
cause overexposure. If it is positioned farther the license plates will be relatively less bright and the image
quality might be deteriorated since more gain will have to be applied by the camera in order to make the
license plates bright enough for ALPR. A solution to this would be to increase the light intensity of the flash
unit.
If the distance from the camera to the trigger line is further than 50 ft then the spacing between flash and
camera will have to be increased to avoid increasing the retro-reflectivity effect, and the flash light
intensity will have to be increased or else the background will not be visible in the image even when retroreflective license plates are close to saturation.
