1. Package Installation:
- Connect to the axis setup page and select “Applications”
- The following page is displayed:
- Press “Browse” and select the correct installation file, placed in the “Setup” folder of
the installation CD1:
- use InnoEDGE_1_3_ARTPEC-4.eap for Artpec4 Axis cameras;
- use InnoEDGE_1_3_ARTPEC-3.eap for Artpec3 Axis cameras;
- Press “Upload Package” to upload the selected package into the Axis camera, then
the application InnoEdge will appear into the “Installed Applications” list:
- The application can run without a license, but with limited functionalities.
- Visit http://www.InnoEdge.com to purchase your license.
- Once installed the parameters of the application can be modified.

Contact Axis for exact camera specifications
In order to modify the parameters click on “InnoEdge Settings”, placed into the left
side of the “Application Packages” page.
- The following page is displayed:
2. Applicable parameters:
Parameter
Meaning
Values
IMAGERES
Resolution of the processed images.
This affects the number of frames InnoEdge
processes per second. On an Artpec4 camera
InnoEdge can process 4fps at a res of 640x480.
HMIN
DEFAULT: HALF_FRAME
Minimum height in pixels of detected plate
characters and numbers.
FULL_FRAME: InnoEdge uses main
stream res
HALF_FRAME: InnoEdge divides
main stream res by 2
QUARTER_FRAME: InnoEdge
divides the main stream res by 4
A value in the range 16-100.
Advised minimum height 20 pixels.
HMAX
DEFAULT: 20
Maximum height in pixels of detected plate
characters and numbers.
SERVERIP
DEFAULT: 40
IP Address of the server where the resulting
detections of InnoEdge engine are sent to.
A valid IP address
PORT
DEFAULT: 192.168.2.49
Port number used by the server to receive the
resulting detections from InnoEdge.
A valid port from 1 to 65000
PLATEBUFFERLEN
DEFAULT: 1234
Number of consecutive frames used by InnoEdge to A value in the range 1-30
start the recognition.
NUMMINREC
DEFAULT: 4
Number of same recognitions in the buffer that
define the final output.
SAMEPLATETIMEOUT
DEFAULT: 2
Number of seconds InnoEdge ignores plates when
equal to the last.
A value in the range 1-3600
USETEMPLATE
DEFAULT: 60
Allow the system to use country templates and
improve the recognition quality.
YES or NO
ROISTARTX
DEFAULT: YES
Start point of the ROI horizontal axis.
Number in 10th of % vs left side of image
ROIYSTARTY
DEFAULT: 0 – means start at left of image
Start point of the ROI vertical axis.
th
Number in 10 of % vs bottom of image.
ROIWIDTH
DEFAULT: 0 – means start at bottom of image
Horizontal width of the ROI.
th
Number in 10 of % vs ROISTARTX.
ROIHEIGHT
DEFAULT: 1000 – means entire image
Vertical height of the ROI.
Number in 10th of % vs ROISTARTY.
Advised maximum height 50 pixels.
Value >= HMIN.
Value <= PLATEBUFFERLEN.
ROISTARTX + ROIWIDTH <= 1000.
ROISTARTY + ROIHEIGHT <= 1000.
DEFAULT: 1000 – means entire image
3. Graphical representation of ROI set-up:
It is recommended to define the ROI to measure approximately 640x480 pixels.
This should be calculated versus the total image settings.
Example:
With an image resolution of 1280x720
Set ROISTARTX at 250
Set ROIWIDTH to 500
Set ROISTARTY at 250
Set ROIHEIGHT at 500
This means ROI is defined from ¼ of the left side and spans half the image.
Likewise, the ROI starts from ¼ of the bottom and spans half the height.
Thus the ROI measures 640x360 pixels.
4. Algorithm output:
MJPEG STREAMING:
An MJPEG Stream delivering the detection results is directly available.
In order to show the stream open a web browser and go to
www.IPCAMERA/local/innoedge/analyze.cgi
When a plate is detected, the result of the detection is placed on the top-left side of
the image.
This streaming is available also if the application is not licensed.
SERVER2:
Innoedge can send the result of a recognition to via network to a socket
server/listener application.
The port on which InnoEdge and the external application communicate can be
defined in the InnoEdge application settings (see “Applicable parameters”).
When InnoEdge detects a new plate, it sends the following string to the server:
<INNOEDGE>
<PLATE>DETECTED_PLATE<\PLATE>
<DATE>DETECTION_TIME<\DATE>
<CONF>PLATE_CONFIDENCE<\CONF>
<HCAR>PLATE_HCAR<\HCAR>
<\INNOEDGE>
wherein:
DETECTED_PLATE represents the detected plate, e.g. “AB123CD”
DETECTION_TIME represents the time stamp, in format DD-MM-YY HH:MM:SS
PLATE_CONFIDENCE represents the quality of the recognition, in the range 0-100
PLATE_HCAR represents the height of detected plate characters.

This functionality is available only for licensed applications
5. Licensing the application:
In order to license the application go to the setup page and select “License” in the
InnoEdge settings form.
The following page is displayed:
Press “Select” and navigate in order to select the license file, provided by InnoWare.
Press “Install” to install the license.
Upon completion the following page is displayed:
In the overview pane “Application Package” “YES” will appear in the “License
Installed” field.
