1.3 System Components description
1.3.1 Traffic Light Sensor – TLS300
The JAI traffic lig h t sensor is the driver of the VIS control network. It controls video signal parameters of each camera to ensure high contrast images of passin g vehicles and th e ir lice n se p l ates, regardless of vehic l e speed, weather or ambient l ight conditions.
Under the clear plastic dome of the traffic light sensor are mounte d, in opposing direct io n s, two vertical plates and corresponding l ight collection staffs t hat 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, th e other one is in shadow. The se two measurements identify the range of light levels that the camera is required to image without satu ration when a vehicle and its license plate are in t h e camera’s field of view (FOV). To ensure correct functionality of the TLS-300, it is very important to en su r e dur in g installation, that the sensor’s base plate is lev e l e d 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 b y t h e tr affic camera (see Figure 2).

The TLS-300 light sensor is an essential component that ensures the VIS cam e r as w il l b e ready to capture h igh quality images of any vehicle and its license plate in virtually all w e ather and light cond itions.
It is very important to ensure that sensor p ositioning closely resembles real road condit ions where the vehic le 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 st ate-of-the-art prog r e ssive interline transfer CCD that captures all of the vertical resolution at once, thereb y el iminating 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, the VISCAM 400 houses the TS-2030EN, and the VISC A M 500 houses a TS-4032EN Ethernet camera with a built in I BM Power PC using an embedded Linux O/S for various operations, su ch as frame store, JP E G compression, vehicle fin gerprint extraction, license plate find, running applications, and so o n .
When the TLS-300 Traffic Light Sensor is used to control the VISCAM exposu r e settings, no moving p ar t s (such as an auto-iris lens) are in c lu ded in the VIS system. This helps ensure high reliability for the syste m .
A 12.5 mm to 75 mm manual zoom lens is provided as a st andard with the VIS C A M 3 00. This allows the VISCAM to be mounted in a wide range of positions while ensurin g sufficient resolut ion o n the vehicle license plat es. A 35 mm fixed focal len gth lens is provided stan d ar d w ith the VISCAM 400. A zoom lens is also available as an option. An anti-glare pol arizing filter is mounted in front of the lens to reduce smear in the picture caused by sun glints. A 50 mm f ixed focal lens is provided standard with the V I S C A M 500.

4 Introduction
1.3.3 Illumination
1.3.3 (a) TNF-31 Flash The TNF-31 Flash ge n e r ates light in wave l e ngths that are invisible to the human eye, but visible t o the camera.
This makes the flash su itable for illuminatin g both oncoming and receding views of traff ic. Unlike near-infrared illuminators, the TNF-31 yields high cont rast images of license p l ates even if they have red characters on white or yellow backgrounds.
The TNF-31 Flash is aut omatically enabled w h enever the TLS-300 Light Sensor determines that ambient light is insufficient to pr oduce a picture of usab le quality. When the TNF-31 is enabled, it fires eve ry t im e the vehicle detector triggers the camera.
1.3.3 (b) White light LED. JAI offers White L ED s m ou n ted inside the camera en cl osu r e. This option is usu all y employed when certain rare
color combinations on license plates do not yield sufficient contr ast 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 mounte d P C B equipped with various interface terminals for interconnection of the VIS components; this can be Ethernet connection, serial conn ection, TTL trig ger feed and power supply. It offers the possibility of manually selecting trigger polarity to the camera. Furthermore th e J-Pan e l is equipped with statu s L E D’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 ENS etup Program.
The ENSetup Prog r am is an Ethernet based software tool specifically d e signed to assist the in staller with VIS installation, and E N -Camera configuration and diagnostics. Th e program runs on a standar d PC / Laptop with Windows XP installed. Refer to Section 4 of this manual and the VIS C A M 300/4 00 E N S e tup Manual for details.
1.4 Operational Overview.
During installatio n , the VISCAM and the op tional light source are aimed at the area of the road w h ere vehicles and their license p lates are most likely to pass through. The Traffic Light Sensor continual l y registers the ambient light. The camera uses this informat ion to set up exposure v ar iables to ensure an optimal im age of the vehicle and license plate. During transition from day to night th e came ra e n ables the optional TNF-31 Flash and/or white light L ED ’s to secure adequate image quality during l ow ambient light condition s.
1.4.1 Trigge r 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 Preparing for installation
2.1 Installation Preparation
To prepare for inst al lation, consider the f u ndamental requireme n ts for an effective de p l oymen t of the Vehicle Imaging Subsyste m. There are two basic way s to position the camera: ov er the lane or beside the lan e . Figure 3 and Figure 4 depict a typical over-lane installation. Figure 13 and Fig u r e 14 depict a typical beside-lane camera installation.
2.1.1 Over Lane Positioning
Over lane camera moun ting is always employed w h en the road width bein g monitored contains more than two lanes of traffic, w h en a convenient overhe ad structure is already in place, or when prevent in g 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, 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 (@ 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 t il t considerations
The requirement to freeze the motion of high-speed vehicles limits how steep o r shallow the tilt angl e o f th e camera may be. For e xample, it is important t o prevent the horizon from appearing in the image , and thereby allowing the sun t o blind the camera. For over lane in stallations, a camer a tilt between 20° to 30° i s recommended–with 25° be ing considered the opt im al angle. This angle of tilt is the best compromise b etween minimizing visibilit y blockages caused b y c lo se l y sp ac e d vehicles and maximizin g plate visibility for plate mounts that are slightly recessed or tilt e d downwards.
2.1.1 (b) Asynchron ou s triggering consider ations
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 b oth the vehicle and its licen se p l ate. The delay between the time the vehicle passe s the trigger position on the road and when the trigger signal actually reaches the V I S must be kept to a minimum to prevent high-speed ve h icle s f rom moving out of the area viewed by th e camera before the image is snapped.
2.1.1 (c) Camera height versus trigger d istance considerations
It is critically important, to select the correct distance b e twee n t he camera and t he location on the road where the camera is trigge r e d to capture an image. M in imizing the cost of inst al lation is usually also an imp ortant concern. This means t hat whenever possible, it is best to use exist in g structures or prev iously in stalled elements. The following ch arts (Figures 5 to 12) provide a wide range of trade-offs between camera heig h t and trigger distance to enable the installer to se lect convenient came ra an d light sensor locations re l ative to existing mounting structures and ve h ic l e trigger locations. Adhe rin g to the installation options provided in th e installation charts, yields camera images that are generally su itable for automatic li cense plate reade rs (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) 408 383 0300.

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.

structue.
Generally the f lash h e ad must be separated from the camera by a radial distance of at least three and a hal f feet (1.2 meters).
If the flash is positione d cl oser to the camera, r e flections from the license plate will cause overexposure. If possible, position the flash head in leve l with the reference plan e sh own in Figure 15. This plane is in level
with the top surface of the camera enclosure, but slices throug h t h e center of the le n s.

3 Installing the Vehicle Imaging System
The individual comp o n e n ts of the system is electr ical l y linked together as sh o w n in Figure 1, “VIS elemen ts”. The VIS CAM camera h as c on n ections to the J-Panel an d an opt ion al Fl ash, 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 th e Traffic Light Sensor e nsure the unit is positione d higher than either the camera or the flash unit so the A-side is in direct sun whe n ever the targeted vehicles license plates are. See Section 2.1 for general site layout guidel in e s.
It is extremely im p or tant the light sensor be p r operly positioned at t h e sit e . The light sensor must be placed so that no shadows from su r ro u nding structure s ar e c ast on side A when the licen se plates being imaged by the VISCAM are in direct su nlight.
Because sun angles at an y given site can change ac co rding 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 T o in stall the Traffic Light Senso r :
1. Disconnect Power
2. Loosen the four hex screws and remove the flange from the mounting base. See Figure 16.
