1 Introduction
For a Quick Start Guide, please refer to appendix G at the end of this manual.
1.1 Document Overview
This manual is a supplement to the Vehicle Imaging Subsystem 300/350/400 (VIS-CAM 300/350/400)
manual. References are made to this manual wherever applicable. This manual can be downloaded
from the JAI website.
1.2 IIT Overview.
The IIT camera is an all-in-one Intelligent Traffic Surveillance camera. The functionalities include:
1. In Image Triggering System
• Automatic detection of vehicles
• Measuring the scene light condition
• Setting up camera gain, pedestal and exposure time based on scene light condition
• Grabbing the picture
• Reading the license plate
• Transmitting the data via Ethernet or optional wireless interface
The IIT camera IR Illuminator provides sufficient illumination to produce pictures of license plates at
night time. Output for controlling an external flash is provided if total vehicle illumination is
required.
The IIT camera is based on the standard JAI Traffic Solutions EN camera platform and includes a
variety of picture formats:
1392 (H) x 1040 (V) (VIS-CAM 350 IIT)
1920 (H) x 512 (V) (VIS-CAM 400 IIT-2030)
1920 (H) x 768 (V) (VIS-CAM 400 IIT-2076)
The standard cameras are combined with an optical fiber front end for vehicle detection and light
measurement as well as a dedicated IIT I/O Board and an IR Illuminator.

12 Introduction
IIT Camera System Manual
The concept of the IIT Camera is to exploit the retro-reflective properties of the vehicle license
plates. A retro-reflective surface returns the incoming light in the same direction it comes from.
The IIT camera is equipped with a number of emitting infrared diodes that are positioned evenly
across the camera lens. The light is frequency modulated. A beamsplitter is mounted in front of the
CCD for distribution of the incoming light to both the CCD and an array of optical fibers. The optical
fibers are connected to photodiodes on the I/O board.
Figure 3. Camera front with beamsplitter and fibers
Infrared modulated light is continuously transmitted from the camera’s IR illuminator. The reflected
signal caused by a license plate on a passing vehicle is correlated for correct modulation frequency,
phase, amplitude and the number of high samples. If the trigger criteria are validated as correct, a
trigger is generated and an image is grabbed.
The light sensor values – shutter, gain and pedestal that ensure optimal image acquisition properties
– are sampled from the reflected signal simultaneously.
Due to the optical inverting properties of the lens, the retro-reflective sensitive part of the picture
is positioned in front of the lower part of the CCD even though the fiber array is located in the top.
Figure 4. The sensitive region of the picture area
This illustration shows the sensitive region and the way the vehicles must pass it to make the system
function.
Introduction 13
IIT Camera System Manual
Vehicles are detected from both driving directions (front or rear shots). The system will only work
if the license plate is moving through the retro-reflective sensitive region of the picture area.
Other parts of the vehicle being retro-reflective can cause generation of triggers. These parts can
be the tail light or stickers of different kinds.
Besides the special IIT functions, many of the I/O Board functionalities from VIS-CAM 300/350/400
are available. This includes output for camera heater, output for external flash and 24V auxiliary
output.
If only the IIT trigger functionality is used (excluding the internal light sensing feature), the camera
can be mounted together with an external light sensor. For details regarding Light Sensor
positioning and configuration, please refer to VIS-CAM System Installation manual.
The J-Panel (Junction Panel) described in the VIS-CAM System Installation manual is also applicable
in conjunction with the IIT camera.
