1. INTRODUCTION
The Vidar Axle Counting camera scans the vehicles from the side and generates laterally directed
events assembled from parts about the passing vehicles, on which additional engines can be run, for
example: VAC engine (Vehicle Axle Counting). The camera employs a lateral scanning approach,
generating comprehensive events that capture crucial details about passing vehicles. The Vehicle Axle
Counting (VAC) engine is instrumental in accurately counting the number of axles in passing vehicles.
Axle counting is critical to traffic management, providing valuable insights into traffic flow, vehicle
types, and overall road usage.
The lateral scanning mechanism of the Vidar camera distinguishes it from conventional surveillance
systems. Unlike traditional methods that focus on frontal or rear views, Vidar scans vehicles from the
side. This lateral perspective allows a more detailed and nuanced understanding of vehicle
characteristics.
After the proper settings, the following result can be achieved:

Overhead installation - - when the camera is placed above the lane:
•Installation height: 4 - 12 m
•Maximum tracking distance for detection: 3.5 - 8 meters
•The camera can capture the closer lane or the adjacent lane
•The tilt can be up to 65°
•If the camera is monitoring the adjacent lane, there might be an occlusion due to
passing vehicles
•Illuminator can be mounted under the camera with the same tilt
Offset from lane center [m] –(The calculated values are for a standard lane width of
3.5 meters.)

The angles and distances specified in the manual were determined based on realized and operational
projects. Deviation from these angles is reasonable within the limits of Adaptive Recognition
knowledge base.
In the case of extreme installation requirements, individual assessment is necessary.
If you have a location with different conditions, please do not hesitate to contact us for more
information!
Transversal installation - when the device is installed on a pole near the road and it has to
be:
•Install perpendicular to the road
•Maximum tracking distance for detection: 3.5 - 8 meters
•Installation height: 1.5 - 4 m
•The camera should always capture the closer lane
•It should not be tilted too much (max. 10°)
•The recommended installation height should always be at the lower limit, taking the
conditions into account
•Illuminator can be mounted under the camera with the same tilt

6. ACCESSING THE CAMERA
•Ensure that the camera and the computer are connected to the same network.
•Enter an alternate IP address or set your computer’s IP in the 192.0.2.x subnet, where x is an
integer between 1 and 254 except 3. Set the subnet mask to 255.255.255.0.
Beside the fix IP configuration, you can use DHCP based network too.
•Start a browser then enter http://192.0.2.3 address into the address bar. This is the camera’s
default IP address. Further information on setting up the camera can be found in the Vidar
User Manual (Section 5).
7. DATE AND TIME
Current date and time and timekeeping settings are managed in the Date and Time section of the
camera web interface. Users have the option to set date and time manually, or use a time
synchronization protocol (NTP) which will keep time synchronized with a server over the network. For
further details, please refer to the Vidar User Manual (Section 5.2).

Hardware Key Licenses currently available in the device are listed in the License Manager section.
Additional licenses (sold separately) can be installed in the Upload License menu.
You should have already received your license file from your sales contact person which will enable
the latest recognition engines to run on your camera. If you do not already have your license, please
contact your salesperson or ATSS (open a new support ticket) to request that it be sent to you again.
This is important because the recognition engine you will install will only run if you also have the
correct updated license file uploaded into your camera.
The proper selection of engines is always based on licenses. Users should search for and download
the latest version containing the names.

9. SETUP CAMERA
9.1. STREAM SETTINGS
Next, Side scan setting needs to be turned on for Sensor #1 under the Stream settings.
A selector or drop-down menu will appear, always select Sensor #1.
At Sensor #1, select the highest frame rate from the drop-down menu next to the highest resolution.

With the Sidescan function is activated for Sensor #1, the user proceeds to the ANPR menu and
navigates to the ANPR settings submenu. Here, within the Processing stages sub-point, the VAC
function is selected. This step ensures that the camera is configured to accurately count axles in the
monitored zone.
To enable VAC option, you must enable Sidescan feature under Stream Settings
menu first.

9.2. OPTICS
The first step is to set the appropriate Zoom-Focus.
It needs to focus on having a zoom setting that includes the whole vehicle in the frame. The bottom
and top of the vehicle should be fully within the frame, and the image should start where the asphalt
(edge of the lane) begins. We can use the Auto Focus setting for a sharper and more accurate image.

9.3. SIDE SCAN SETUP
Go to the Live view menu, and select the Side Scan submenu. If the lane separator is not horizontal, it
is advisable to align it horizontally. If you notice any distortion in the image, use the MSQ and MQD
sliders to flatten the image.
MSQ: it adds or removes spherical distortion occurring within the main area of image.
MQD: it adds or removes spherical distortion occurring within the outer edge of image.
Rotate: align the picture horizontally.
In the Direction section, you can select which way the camera should measure. This also depends on
the installation location, it must be selected according to the specific environment. Always specify the
appropriate direction.
Reverse sign: Due to the two directions, one appears positively (e.g., moving to the right), while the
other appears negatively (e.g., moving to the left). If the user wants to see this reversed, it can swap
this sign.

9.4. DETECTION AREA
By pressing the Detection Area button, you can set the desired detection area on the image where the
vehicles pass entirely.
To achieve the best detection zone settings, the following considerations are needed:
•Exclude the sky, and avoid having too much space below. If you want to see the wheels, leave
a bit more space downward.
•It is more practical to focus on the wheels because, it cannot handle very homogeneous areas
(e.g., truck canvas).

The results can be found in the ANPR Browse menu.
If you choose the info button , and in the Data group section, the VAC data will be shown, if
you choose it from the drop-down menu.
The displayed result on the image provides the number of axles, the total vehicle length, and the
distance between the axles.

10. TROUBLESHOOTING
Troubleshooting:
•The image is not sharp:
oThe correct configuration of the zoom and focus pairing is crucial to ensure
that the camera captures sharp, detailed images. The typical setting for zoom
is around 0, paired with the corresponding focus.
•Distortion in the image:
oThe image should be horizontal.
oUse the MSQ and MQD sliders to flatten the image.
•No events are being generated:
oActivate the Side scan function on Sensor 1 in the Stream Setting menu.
oInstall the VAC engine on the camera.
oActivate VAC processing stage on ANPR Settings menu.
oThe detection area is not set properly
