Security markets. JAI manufactures core imaging cameras and vehicle imaging products
and services for worldwide traffic industry partners.
General Description
The next-generation JAI Vehicle Imaging System (VIS) is a high-performance
imaging solution for advanced ITS imaging applications, including auto-
mated license plate reading systems and vehicle fingerprinting recognition
applications. The VIS is field-proven to produce high-contrast images of
passing vehicles and their license plates under all weather and lighting con-
ditions. Retro-reflective and non-retro-reflective license plates, even older
plates, are easily captured by the VIS in combination with JAI illumination
solutions, 24/7.
The JAI VIS is suitable for multi-lane use in either lane-based or high-speed
open-road applications. The VIS captures full-frame images on demand from
a variety of vehicle detection triggers. It can also be set to generate 30 full-
frame (768 pixels by 484 lines, or future release 2k x 1k) images per second.
This quality resolution (progressive scan) is critical to ensure plate legibility.
JAI can provide a variety of VIS nighttime lighting options to help your
system generate high-quality images at night. These options include
continuous lighting (TNC-1000), as well as nighttime flash lighting (TNF-21 or
TNF-31) that can accommodate the ever-widening range of plate color combi-
nations. We can even handle those situations in which near-infrared lighting
cannot produce legible plate images. All available VIS lighting options meet
road safety standards.
Unlike other imaging systems, the JAI VIS Subsystem adapts instantly to
changing lighting conditions, even when there is no vehicle in the camera’s
field of view. This intelligence is made possible by a JAI patent-pending
Traffic Light Sensor that continuously measures the instantaneous dynamic
range of plate/vehicle brightness and electronically adapts camera param-
eters (such as gain and shutter speed) to achieve optimal imaging. Because
the camera uses no mechanically moving parts (i.e. auto-iris lens) are used,
it is much less likely to fail. Please refer to our separate specification sheets
for further details of the VIS components.
The light sensor and VIS cameras communicate over a local VIS network
utilizing Ethernet communications. VIS subsystems can report the health
and status of all components to any IP address on the network.
The VIS traffic camera utilizes a state-of
the- art progressive interline transfer CCD
that captures all of the vertical resolution at
once with no field-to-field imaging delays.
Progressive scanning allows the VIS camera
to capture a rapidly moving vehicle at high resolution without the need for a
mechanical shutter. VIS camera provides two resolution options for various
lane widths and comes complete with zoom lens, antiglare filter, and interface
circuitry in a heated weather-proof enclosure.
Smart Light Sensor (TLS-300)
The patent-pending JAI light sensor is the driver of the
VIS Network. It continuously monitors the ambient
lighting conditions, then computes shutter, gain, and
pedestal settings for the cameras on the network to
ensure high-contrast images. These commands are
then broadcast over the VIS Ethernet network every
1/10 second to keep the cameras up to date with even
the most rapidly varying ambient lighting conditions.
A single light sensor is commonly used to control up to twenty cameras for
multi-lane applications.
VIS Junction Panel (VJP300)
The VIS Junction Panel makes site installation quick
and easy. The Junction Panel is the interface between
the JAI VIS Subsystem and the rest of your system. It
is used with a DC output power supply (AC PSU) for
the cameras and light sensor, and terminal blocks to
simplify connecting trigger input, host interface and intercon-
necting cameras and light sensor.
Nighttime Illuminator(s) (TNF-21, TNF-31, TMC-1000, LED-12)
Three lighting options are available for the VIS
Subsystem. The TNF-21 or TNF-31 Traffic Night
Flash is an 18W long life (up to 4 million flashes)
dual-band flash unit. The flash filters light to
wavelengths invisible to the human eye, which
means it is well suited for both front and rear
vehicle imaging. The TNC-100 is a 70 watt
continuous white-light lamp and a focusing
reflector enclosed in an outdoor fixture. It il-
luminates up to one-and-a-half lane widths with
white light. The amplitude of the light can be set
to achieve a wide range of illumination levels.
A unique feature of this gas lamp is its ability to
produce very bright light that is stable over very
short exposure times, without brightness oscil-
lations. In contrast, the brightness of most gas
lamps oscillates at the AC frequency, which produces unsatisfactory pictures
at the high shutter speeds needed to freeze fast-moving vehicles. Because the
TNC-1000 is extremely bright, however, it is only suitable for rear imaging of
vehicles.
The LED-12 illumination ring is a 6 watt ultra long-life (>100,000 hours) low-in-
tensity white-light illuminator. It is incorporated into the camera housing and is
suitable for front or rear vehicle imaging. The LED-12 is used in those situations
where certain license plate color combinations are difficult to image with the
flash alone.
