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).

Figure 2. Back shot VIS installation.
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 3. Typical Over Lane Site Layout
VIS-CAM Systems
6 Preparing for Installation
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.
VIS-CAM Systems
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.

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.

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.

3.2 Installing the Camera(s)
In general, the camera(s) should b e aimed at the most likely c r oss-lane position of the v ehic le license plates. See “Installation Pr e paration” in Section 2 f or general site layout guid elines. To install the camera(s):
1. Attach the camera mount to the camera enclosure using the included mounting bolts and washers.
Figure 20. Camera Installation
VIS-CAM Systems
2. Align the camera enclosure mounting surface with the hole pattern of the camera mount and secure it to the camera mount with the five provided ¼-20 hex bolts.
3. Attach the camera, with mount, to the mounting structure. The hole pattern is shown in Figure 21 Below
Figure 21. Camera mount template.
4. Route the camera end of the camera cable according to the camera IAW local electrical code Requirements
5. The jacket is removed from the cable in the camera end and the wires are stripped as shown in the Figure 16 below. There are two sets of four twisted pairs. Four of the pairs are for ethernet signals. These pairs are individually foil shielded and have a common braid shield. The other four pairs are individually foil shielded without the common braid shield. The shield on the Ethernet pairs must be run as close to the connector as possible. All wires must be stripped for insulation app. 7mm.
Figure 22. Camera cabling as it appears before electrical installation.
6. The cable is separated into the Ethernet part (with the braid shield) and the power and control part (the rest). Each part is fastened with cable ties to the respective cable relief’s on the terminal block X4 on the VIS-CAM I/O Board.

The cable from th e fl ash unit is connected to th e V IS CAM I/O Board as shown in figu re 3.17 and 3.18. There ar e two examples shown: one where the ou t p ut circu it on t h e I/O Board is pow e re d f r om t h e flash unit and one where the output circuit is powered from the I/O Board.
It is recommended that I/O Board output c irc u it be powered from the flash unit in order to obtain galvanic isolation between the two units. In cases w h ere this is not possible (suc h as when using mains supp lied flash units) power is tak en from the I/O Board.
The cable must be shielded and the shield connected to the metal at the cable entry in the camera house. The switch labeled S3 on the VIS CAM I/O Board must be in position “NIGHT L” (away from connector X5 as show n below).

4 System Set-Up
This section provides a generic procedure f or align ing on e or more of the VIS CAM cameras and their associated equipment at a site. If you received a specific installation manual f r om J A I for your project th e n foll ow those instructions inste ad of the procedure described here.
The example inst al l at io n process described in th is section assumes that:
• The cameras are being mounted on an overhead structure directly over the lane(s) being observed. The process for aligning a camera mounted at the side of a lane is essentially the same as aligning a single camera mounted directly over the lane.
• The site employs an accurate vehicle detection device that outputs a discrete TTL signal to the VIS system whenever the back (or front) of a vehicle crosses a fixed line across the road. This line is referred to as the “trigger line” in this document. Examples of such triggering devices are: Peak’s trafficLoop, STI’s Vehicle Detector light curtain, and JAI’s Laser Vehicle Detector.
• License plate reading or vehicle matching is performed on the images produced by the VIS system. In these cases, precise location and alignment of the cameras is critical to project success. If the VIS images are only for human interpretation, then achieving the exact camera alignment is much less critical.
• The installer is familiar with using the ENSetup program supplied by JAI. Please refer to the ENSetup Program User’s Guide if you are unfamiliar with this software. JAI offers engineering support and software tools to help select the optimum camera and trigger locations to meet your specific project needs. Contact ITS Engineering Support at (408) 383-0300 for further information about obtaining JAI assistance.
4.1 Preparation for Alignment
4.1.1 Pre-Alignment Checklist
• Make sure you have a JAI supplied setup computer with the ENSetup program installed.
• The Setup computer needs to have an Ethernet network adapter installed (preferably 1 Gigabit
Ethernet Adapter) and the TCP/IP network configured with the correct IP-address, subnet-mask and default-gateway.
• The Setup computer and the cameras need to be on the same subnet. The cameras are shipped with the standard IP-address “10.0.0.65” and subnet-address “255.255.255.0”, and the Setup computer needs to be assigned an IP-address “10.0.0.xx” in order to automatically discover the cameras using the ENSetup program (NB! “xx” must not be “65”).
• All cameras have to be given unique I P -addresses before the alignment begins. This is done using the ENSetup application.
• Confirm all VIS CAM components and cables are properly connected.
4.1.2 Select a Suitable Vehicle, License Plate, and Plate Stand for the Setup
To accurately set u p t he Vehicle Imaging Sub sy stem, the system installe r s n eed access to:
VIS-CAM Systems
34 System Set-Up
1. A vehicle that can be temporarily parked on the road
2. A plate that is: a. typical in size and color for the site b. clean, flat and in “like new” condition
3. An adjustable plate stand that allows the plate to be mounted in a vertical plane, at various heights above the road, and at variable roll angles. The stand must allow the plate to be placed at both the nominal plate height and the minimum expected plate height. The stand must also allow the plate to be rolled at least + or – 10 degrees from horizontal but held firmly in place once a specific roll angle is selected. The stand should be heavy enough so that the wind will not blow it over or move it.
Table 11 Typical minimum plate heights and nomina l pl ate heights:
Plate Height
Front of Vehicle
Back of Vehicle
minimum (bottom edge)
8in or 20cm
15in or 38cm
nominal (middle) 16in or 40cm 24in or 60cm
4.1.3 Select the Camera to Align
• If the site employs a single camera per lane, then you can choose any lane to start the
alignment procedure.
• If the site employs multiple cameras regularly spaced across a roadway to provide continuous
fieldof- view coverage from edge to edge, select one of the cameras at either edge of the roadway to be the first camera to align.
• Align all remaining cameras in order from the first camera aligned to the last camera at the
other side of the roadway. The next camera aligned is always the one adjacent to the camera most recently aligned.
4.1.4 V alidate the Installation Geometry
The VIS cameras and vehicle trigger line sh ou l d have been installed at the locations agreed to by you and JAI. Typically JAI util izes a specially developed Excel worksheet to confirm the suitability of the equipment placement at the site from an image processing perspective. See Figure for an example worksheet. However, equipment is often not located where the worksheet specifies. It is therefore imperative that the actual equipment layout at any given site be measu r e d to verify that the came ras and trigger are located at the desired locations relative to each othe r. If necessary, move t h e cam e r a/trigger positions until the distances required in the w or ksheet are met. If it is no t p ossib l e t o move the equipment t o th e r e qu ired locations, then the impact of any ch an ges to the subsequen t image processing must be assessed. Enter the actu al c ame r a locations into the I nput section of the JAI w o rksheet and then note the changes in the Results section. If there are any questions abou t the suitability of a specific camera/trigger layout, contac t your JAI representat iv e for advice.
4.1.5 Edit the alignment settings on the Setup Computer
In order to carry out the alignment properly, the ENSe t u p program has to be conf ig u red with t w o v alue s f rom the worksheet. S e e t he E N S e tu p P r ogram User’s Guide (Video W in dow Setup section) f or details on changing Video Window properties.
Using the ENSet up p r ogram, make sure the “tilt line” and “plate num cols” items on your Portable Setup computer are exactly the same as the measu r e m e n ts, including the prop e r plate size parameters measu red in Section 4.1.4, “Val idate the Installation Geometry,”. All oth e r c ame r a settings should already be correct for the site installation , but it is a good idea to v erify that this is true b e fore proceeding. The Set u p Comp uter is now properly configured to support lens adjustments and camera aiming.
VIS-CAM Systems
4.1.6 Co nne c t th e Setup Co mputer to the Camera
• Position the Setup Computer next to the camera being aligned. If the alignment is conducted in bright sunlight, shield the monitor screen with a hood to make it visible. Make sure that no portion of the computer or cables interfere with the camera’s view of the road.
• Connect the Setup Computer’s network adapter with the camera network. This can be done directly to the I/O boards X1 and X3 connectors or using a local Ethernet switch. It is preferable to use a local Ethernet switch instead of a local direct connection to the I/O board. A direct connection between the Setup computer and the camera will disconnect the camera from the site LAN and thereby disconnect the light sensor as well.
Figure 36. Example of a network connection using a local switch.
The network connection between the Setup comput e r an d the c amera can be established u sin g a local switch. Two separate ports of the Ethernet Switch are connect ed directly t o t h e I/O b oard conn ectors X1 and X 3. The Setup computer is then also connecte d to one of the free ports on the switch. If the switch is running on 24V dc, the I/O board is capable of supplying up to 0.5A on connector X15 located next to X1 and X3. The pin marked with #1 on X15 is +24V d c.

36 System Set-Up
4.1.7 Drive and Park the Setup Vehicle Correctly
• Drive the setup vehicle slowly towards the trigger line through the center of the cameras field of view in the same manner (heading) as a typical driver would occupy this lane.
Note: This is important, make sure that the vehicle is driven exactly the same way as the average
driver would through the section of roadway being viewed by the camera.
• Stop the vehicle approximately one foot (0.3 meter) past the trigger line. Make sure that the vehicle is parked aimed in the same direction as the average driver would point their car if they were driving through this section of roadway.
• To help the driver of the vehicle properly aim the car while driving, instruct him (or her) to always look forward down the road as they would normally. Use a sound to signal the driver when to stop.
4.1.8 Properly Position the License Plate Stand
Using your portabl e plate stand, position a lice n se plate:
• at the minimum expected trigger distance from the camera.
• at the minimum expected plate height above the road.
• at the location along the trigger line where the center of the horizontal field-of-view of this
camera is desired.
Rotate the plate on the stand until the top and bottom edges are level with the vehicle parked behind the trigger line (to within a + or – a couple of degrees). Secure the plate on the plate stand so that the adjustments you have just made do not change.
4.1.9 P e rf o rm Initial Lens Adjustment and Camera Aiming
1. Back away all of the thumbscrews on the lens holder until they do not touch the knurled
adjustment rings on the lens.
2. Make sure the lens aperture adjustment is fully open (rotate the third ring from the front of the
lens fully counter-clockwise until it stops at the f1.2 setting). Secure the thumbscrew that lines up with the aperture ring until it just presses against the ring. Next tighten the thumbscrew that lines up with the knurled ring closest to the camera body until it just presses against the lens. Do not tighten any Lens Holder thumbscrews beyond a slight pressure against the lens.
3. Loosen the roll, pan, and tilt bolts on the JAI camera mounting head until each axis can be easily
adjusted by hand but any particular setting will stay in place after you let go.
4. Power on the Setup computer and then start the ENSetup program. Press the “Video Window”
button to open the Video Window and then select the camera for adjustment from the tree-view on the left side of the window. Press the “Live” button in the toolbar to start the video streaming. Press the “Tilt Line” button to show the alignment guidelines. The “Tilt Line” can be moved using the mouse, or if the “Tilt Line” is selected, using the arrow-keys.
5. Interactively adjust the roll, pan, and tilt of the camera mount and the lens zoom and focus
rings:
6. Adjust the lens focus ring (and camera pan and tilt as necessary) to obtain a focused image of the
plate on the plate stand. If at any time you cannot fully focus the plate because the focus ring on the lens has reached the end of its turning movement, perform the back-focus procedure described in the JAI document titled “Zoom Lens Back-Focus Procedure.”
VIS-CAM Systems
7. Adjust the lens zoom ring to obtain a plate width approximately equal to the distance between the short vertical sizing marks that appear above the tilt line. Readjust focus as necessary. See Figure 31 for more information.
Figure 37. Initial Camera Alignment Display example.
8. Turn on the “Roll Bar” display on the Setup computer and then roll the camera mount until the horizontal bumper and trunk seams on the vehicle appear perfectly level with the horizontal line of the display. Use one 7/16" closed-end wrench on the roll gear to fine-tune the roll angle. Hold the roll position with the wrench while you use a second wrench to gently tighten the other roll bolts. Then apply both wrenches to corresponding bolts on opposite sides of the mount. Twisting in opposite directions to fully secure all of the roll bolts. This approach prevents the roll adjustment from changing while you tighten the bolts. See Figure 32.
VIS-CAM Systems
38 System Set-Up
Figure 38. Roll Bar Display example.
Pan the camera mount until the plate stand is centered under the default position of the vertical line in the middle of the “Roll Bar” display. Securely tighte n the pan bolt. Be caref u l n ot t o change the p an of the camera while you tighte n the bolt. Oppositely twist in g two 9/16" closed-end wrenches is recommended (one f o r the bolt head and one for the nut) to help prevent the pan from moving while you tighten the bolt.
Switch back to th e “T il t Line” display. Tilt the camera mount until the plate is positioned j u st above the tilt line. Re-adjust the zoom as necessary until the plate just fits in between the zoom markers on the “Tilt Line”. Changing zoom usual ly requires that the tilt adjustment be modified also . Do not tighten the Tilt bolts until after the final lens adjustment. See Figu r e 33.
VIS-CAM Systems
Figure 39. Readjustment of camera tilt and zoom display.
The camera mount and lens are now ready for final adjustment.
4.1.10 Finalize Lens Adjustments and Camera Aiming
4.1.10 (a) Reposition the License Plate Stand at the Nominal Trig ger Line
Use your portable plate stand to position the license plate:
1. at the normally expected (nominal) trigger distance from the camera.
2. at the nominal plate height above the road.
3. at the location along the trigger line where the center of the horizontal field-of-view of this camera is desired.
Rotate the plate on the stand until the top and bottom edges are perfectly level with the vehicle parked behind the trigger line. Secure the plate on the plate stand so that the adjustments you have just made do not change.
4.1.10 (b) Perform Fin al C am era Mount and Lens Adjustments
The final focus adjustment is facilitated u sin g the “Focus Bar” display on the Video Window. Press the “Focus Bar” button on the t o olbar. This displays a “Focus Bar” marker on the Video Window that will open a separate “Focus Bar” window where the pixel-v al u e s taken from the focus bar mark e r is displayed. The “Fo cu s Bar” marker cam be moved with the mouse pointer, or if the “Focus Bar” marker is selected, using t h e arr ow-keys.
1. Position the “Focus Bar” marker directly over the license plate.
VIS-CAM Systems
40 System Set-Up
Figure 40. Focus Bar marker display.
2. Adjust the lens zoom ring until the plate width just barely fits in between the short vertical zoom markers on the display.
3. Have your assistant tape the lens front-focus chart to the stand so that it appears in-between the zoom markers. Make sure the black and white bars are vertical in the image.
4. Carefully adjust the lens focus ring until the focus bar waveform display is maximized in amplitude spread. The “Focus percentage” display shown on the left side of the “Focus Bar Waveform” window should then be maximized when the picture has got the best focus. If necessary, readjust the zoom and focus until the width of the plate is just inside the zoom markers and the waveform spread of the bars is maximized.
VIS-CAM Systems
Figure 41. Focus Bar Waveform display.
5. Gently snug the zoom and focus lens holder thumbscrews against the lens without changing any of
the lens settings.
6. Uncover the license plate by removing the lens focus chart.
7. Use the mouse to move the waveform cursors to the top and bottom of the waveform amplitude
variation. The “Black Cursor” is located at the bottom of the waveform display, and the “White Cursor” is located on the top of the waveform display.
8. Verify that the waveform amplitude variation (for characters in both direct light and shadow, if
possible) is at least 25 and that no portion of the waveform fully saturates either black or white.
VIS-CAM Systems
42 System Set-Up
Figure 42. Focus Bar Waveform Display with waveform cursors.
9. Use one hand to carefully hold the focus ring of the lens in place while you rotate the filter ring on the very front of the lens with your other hand. Turn the filter ring until the white mark on the ring is oriented straight up (or down). Secure the filter ring in place with a small dab of RTV glue.
10. Printout the image of the screen using the “File -> Print…” menus on both the “Video Window” and the “Focus Bar Waveform” windows to document the settings. If no printers are connected, the “PDFCreator” printer driver can be used to save the pictures as PDF-files.
11. Have your assistant move the plate stand back to the near trigger line and re-position the plate at the minimum plate height.
12. Drive the setup vehicle slowly towards the trigger line in the same heading as normal traffic flow and center it directly between the camera being aligned and the adjacent camera that has already been aligned. Marking the position halfway between adjacent cameras at the trigger line with some marker is advisable to help the driver properly aim the vehicle.
13. Park the vehicle at the location where it just barely causes the trigger to cause an image to be captured. For loop triggers, park the vehicle where a vehicle would normally be located when the loop trigger signals the VIS to capture an image.
4.1.11 Flash Head Alignment
The following section p r ovides a general procedur e to align the VIS flash head. Be sure to follow any spec if ic alignment procedure provided with your system.
Align the flash he ad at n ight and after aligning the cameras. Park a light col or e d vehicle underneath the camera and where the vehicle detector triggers the camera.
VIS-CAM Systems
• Press the “Repetitive Trigger” button on the ENSetup toolbar. This will trigger the camera every second. Make sure that the “Ethernet” external hardware trigger is enabled in the “Camera Properties” section “2 – Trigger”, property “External Trigger Source”.
• Adjust the flash head tilt and pan control until the entire back of the vehicle is well illuminated. If necessary, adjust the flash-head pan control to center the flash beam over the vehicle.
• If the flash illumination is too bright for your installation, contact JAI for instructions on how to adapt VIS system parameters to reduce sensitivity to nighttime illumination.
Repeat pressing the “Repetitive Trigger” button on the ENSetup toolbar to stop flash firing. Repeat the above steps for each camera/f l ash.
