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:
• 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.
