Frame Grabber(s)
PC Station

I/O Card +Terminal
Block
Power Supply for SCH
SeeLane Software + DLL+
Sample Client Program
• System includes camera/illumination units, hardware and
software (application + recognition library)
• Automatically reads License Plate number
• Displays, records and transmits vehicle image and recognition
results
• Can compare plate number to data base - and optionally open
gate or activate alarm
Handles single or multiple lanes - 1-6 lanes, each lane with different settings
See/Lane can run in background & send DDE messages to your client application
Easy configuration settings - communication, device interface, sensor types, capture and
illumination modes. Password Controlled.
Selectable illumination and image capture schemes - built-in intelligence and logic
to handle different plate qualities
Large display option for indoor or outdoor messages
(2) Hardware
•Inputs: 4 VIDEO inputs
•One or more boards per PC
•Compatible with standard PAL or NTSC
cameras
•Board is PCI bus mastering agents that
directly store the acquired images into the
PC physical memory without CPU
involvement
Model: Advantech PCI 1751 + cable + TBL interface + cover box
Inputs: sensors inputs
Outputs: illumination control outputs, gate control
Camera/Illumination unit for access-control applications
CCD 1/3” B&W CCIR
varifocal lens up to 51 mm
Weatherproof Case: IP 66
Die-Cast Aluminum Alloy, UV protected
Internal illumination
3-Degrees freedom Mechanical interface

1. Hardware
Serial output options:
1.
Regular (vehicle code & authorized name)
2.
Custom string (flexible formatted string, for
parking systems or outdoor displays)
Serial communication could also be implemented
in the Client application
The DDE message is generated on
every vehicle.
It contains vehicle #, date, lane,
authorized flag, owner name, and optional
image file pointer.
User application can also initiate:
“open gate” - forces a certain lane to open the gate
“sensor”
- simulates a sensor activation
DDE message is transmitted over the network by
SeeData.
The DDE is IDENTICAL as in local SeeLane only lane # is different (set by SeeLane settings or in
SeeData)
Image can be transmitted - but the image’s path is
better. The path can be local or absolute - according
to SeeLane settings
(4) Triggering
(1) By external sensor (dry contact) - best is loop detector
(2) By Client’s DDE message
(3) Software trigger - “SeeRoad” system
(5) Installing
0-0.5m
1-15 m
7m
Trigger is when car steps on the loop
Cam
Cam
0-0.5m
6.5 m
Triggering is when car leaves the loop
Cam
6.5 m
7m
Triggering is both when stepping ON and OFF* the loop
(6) Configuring
The file is used to configure the
SeeCarDLL recognition library to
specific applications, cameras and
plate formats

There are 3 ways to get Application
Settings:
1. Open Settings from the main menu
2. Click on the settings icon in the tool
bar
3. Open Settings with hot key F8
Input - Sensor Pin
Associates TBL (Terminal Block) pin to the lane’s sensor (loop detector).
Range: 1 – max input pin number (1-8 for Advantech IO card)
“Normally Open”: recognition starts when the
input sensor (loop detector) goes from “open”
to “close”. Used for front plate recognition
installation.
“Normally Closed”: recognition starts on
transition from “close” to “open”. Used for
rear plate recognition installation.
Output - Gate Pin
Associates TBL pin to the lane’s
gate output
Video Input – Grabber
Associates frame grabber board to the
camera.
Range: 0 – max number of installed
frame grabber cards
Video Input – Input Channel
Associates frame grabber input pin to
this camera.
Range: 1 – 4 video inputs.
Illumination – LSB Pin
Associates TBL pin to the camera
illumination control LSB .
Capture on Sensor
Defines the timing for start capturing images - in reference to the input sensor. “Rising” when the input goes
to high; “Falling” when the input goes low.
Start time
Defines the time of day to start this capture set. Not used in case of a single capture set. If another set
is defined, the capture set will end at the start time of the next set.
Illumination intensity
Defines the illumination intensity for
the current selected set item. Four levels
can be selected: off, low, medium and
high intensity.
Number of captures
Defines how many images to capture
in the selected set item.
Members Database – Search
freedom
Defines how to perform the match of
the recognized plate to the member
database. Larger numbers make less
mistakes in recognizing authorized
members, but could cause falsepositive errors
Client opens gate
If set - the application will not open
the gate, and waits for the Client
application to send an approval for
opening the gate.
Smart Output
If set – the application will not send out recognition results if there is no recognition.
Images main directory
Defines the local disk path where
the images (or their sub-directories)
are stored. User can use the browse
button (“…”) to select the path from
the existing disk directory, or type a
new path. The application will
create the directory is it does not yet
exist .
Output Share name
If set – a network shared name can
be defined in order to set the
reported image path to a network
drive. This is useful if the message
containing the image path is
transmitted over the network, so the
remote node could access the image
file name using the absolute path.
Networking.
Center IP – IP address of SeeData
Center Server .
Data Port – communication port .
Must be set the same port on
SeeDataCenter Server .
The warning is recorded in the application
Event log and will show as a “yellow” state
in SeeMonitor.
Note that when the recognition rate
increases, the application will write an
information event that cancels the
warning
