ITS101 Installation Manual
1. Introduction
This document describes how the ITS101 has to be installed and configured.
The ITS101 is an automated number plate recognition system for access control applications.
The end user is provided with usable license plate recognition data. The unit handles a number
of I/O's – for instance based on license plate black/white listing – for access control purposes.
The front end of the ITS101 consists of an ANPR camera. ANPR cameras differ from normal
CCTV cameras in that they are specifically designed to capture good, clear images of infrared-
reflective license plates in all weather conditions, day or night. In most conditions only the
license plate will be visible when using an ANPR camera, only on very sunny days other
elements of the surroundings will be visible. The ANPR camera can either be an analog camera
or an ARVOO digital camera.
The images from the ANPR camera are processed using the Intrada ANPR software that is
embedded onto the processing board. Images from the ANPR camera are scanned for license
plates and then optical character recognition algorithms are applied. The end product is license
plate recognition data in the form of a text string, packed in an XML protocol. Together with
this the board handles a number of I/O's for access control purposes.
The ITS101 is meant to be used for stop and go situations. This means that the vehicle must
come to a stand-still in order to give the ITS101 sufficient time to read the license plate.
The ITS101 is running a web service that can be accessed via a standard web browser. This
allows to configure the network, retrieve diagnostic information and perform firmware control.

Figure 4: Screenshot I/O settings page

ITS101 Installation Manual
See Figure 3 for a detailed PCB picture of this LAN connector. Also visible is the sticker with the
MAC-address for this specific unit.
2.6. ANPR Digital Interface
The ITS101 is provided with an ARVOO proprietary ANPR Digital Interface, for a direct
connection to the ARVOO ITS101-CAM digital camera. The default cable length with this
camera is 10 meters, this is also the maximum cable distance. Power for the camera is
supplied by the ITS101.
When you select the ANPR Digital Interface the ANPR CVBS interface (Analog video input, PAL/
NTSC) is not in use. The ANPR Digital Interface can be selected by selecting the proper
firmware. See chapter 5. for more information regarding firmware installation.
This interface makes also use of an RJ-45 connector.
Precaution: This interface is not compatible with any Ethernet standard. Connecting a patch
cable to an Ethernet switch will destroy the switch or the ITS101. Before connecting
the ITS101-CAM make sure the power to the ITS101 is turned off. The ITS101-CAM is not
hot pluggable.
2.7. ANPR CVBS Input
The ANPR CVBS input is a female BNC connector. This analog video input can accept any
standard PAL/NTSC camera. You can select the use of the ANPR CVBS input by activating the
proper firmware. The ANPR Digital Interface is turned off in this case. See chapter 5. for more
information regarding firmware installation.

ITS101 Installation Manual
3. Network configuration
Note: The name AX101 appears on the configuration pages and log messages It can be seen
as an equivalent for ITS101
The ITS101 has Ethernet as general communication interface. This gives LAN (local area
network) access to the unit. If required, access to the unit can be secured via a VPN (virtual
private network) layer running on top of the LAN. For this, correct time settings are required.
As the network is configured via a web browser, a factory network setting is required. The unit
has a factory set static IP address of 192.168.0.240. If this conflicts with the network via
which the web browser tries to access the unit, connect to the unit directly via a crossover
cable.
The web service entrance page can be retrieved via a standard web browser using the address
HTTP://192.168.0.240. The pages 'lan settings', 'openvpn settings' and 'ntp/time settings' are
for configuring the network. These settings are explained in this chapter. The pages 'System
information', 'System log', 'Appl log', 'Dsp log' are for support purposes. These are explained in
section 7.4.1.
The username to use is 'admin', the default password consists of the last 4 digits of the unit's
MAC address in capital letters. This password can be changed via the 'change password' page.
When setting are unknown and you are unable to connect to the ITS101, default factory
settings can be restored by the procedure described in section 3.1.
Precaution: the network is configured via the web service that uses the network. Be aware
not to switch off the Ethernet communication.
3.1. Back to default factory settings
When default network settings need to be restored, because you are not able to access the
unit anymore, the following procedure needs to be followed.
ARVOO Imaging Products B.V. page 12 of 33
Figure 7: Back to Default switch

ITS101 Installation Manual
Power-up the ITS101 unit and wait until the red LED DS12 is flashing fast. At that moment you
have 4 seconds to press the Back to Default switch. LED DS12 is mounted at the right side of
connector J6 at the upper side of the PCB.
Default settings are :
–Ethernet enabled and set to fixed IP address 192.168.0.240
–OpenVPN disabled
–Password restored to default : the last 4 digits of the unit's MAC address (in capital
letters)
As soon as it is possible to access the web service at the default IP address, default settings
are restored. You can then start setting up the network again.
3.2. Ethernet
The unit has a factory set IP address of 192.168.0.240.
To change this address, connect the unit via an Ethernet cable directly to your host PC or via
the LAN. Note that the connecting device must set its netmask such that 192.168.0.240 is in
the same subnet. Using any web browser, open location http://192.168.0.240. Logon via user
admin and password equal to the last 4 digits of the unit's MAC address (in capital letters).
Navigate to the page 'lan settings' for changing the eth0 settings.
Explanation:
•eth0 boot mode has two options in its drop down box: Auto or Manual. Auto mode will
automatically start the LAN connection (eth0) on boot up. This is the only reasonable
ARVOO Imaging Products B.V. page 13 of 33
Figure 8: Screenshot page "lan settings"

ITS101 Installation Manual
option. With the mode Manual you lock up the unit, as you will not be able to connect to
the unit if a reboot occurs. You need to follow the procedure described in Section 3.1 in
order to connect to the unit again.
Warning: do not use the mode Manual as you lock up the unit if a reboot occurs.
•eth0 ip mode has two options in its drop down box; Static or DHCP. Static mode will
assign the IP address, netmask and gateway address listed in the “eth0 ip address” text
box, “eth0 netmask” text box and “eth0 gateway” text box. DHCP mode will request an
IP address from an attached DHCP server.
•eth0 ip address is a text box that allows the user to assign a static IP address for the
LAN connection.
•eth0 netmask is a text box that allows the user to define a netmask for the LAN
connection.
•eth0 gateway is a text box that allows the user to assign a gateway address for the LAN
connection.
After clicking the apply button the new settings will be stored. Only after reboot or after
clicking 're-start' the new settings become active.
3.3. OpenVPN
Communications can be secured by OpenVPN, an open source virtual private network software.
Detailed “how to” guides and software are available at http://openvpn.net.
Note: The date and time settings of the ITS101 unit are important for the OpenVPN
connections, as an incorrect time and date setting can lead to an OpenVPN connection being
rejected. See section 3.4 for configuring the date and time.
The ITS101 runs the OpenVPN software as a client application and as such requires client
certificates and key files to be generated and copied onto the unit in order for the OpenVPN
connection to be established. This can be accomplished by navigating to the “openvpn
settings” page on the web service.
ARVOO Imaging Products B.V. page 14 of 33

ITS101 Installation Manual
Explanation:
•Start OpenVPN at boot: Placing a tick in this tick box enables the OpenVPN daemon at
boot up. If the tick box is left blank then the OpenVPN daemon must be started
manually using the web interface.
•Disable direct LAN connection: Placing a tick in this tick box disables the direct access
to the ITS101 using its Ethernet address. Only the VPN address can be used to access
the unit.
•Ovpn server ip address/hostname: The IP address or hostname of the OpenVPN server
can be entered into this text box.
•Ovpn server port number: The port number of the OpenVPN server can be entered into
this text box.
•Enable tls-authentication: Placing a tick in this tick box enables TLS authentication on
the ITS101 unit (TLS authentication must also be enabled on the server if this option is
selected). A TLS authentication key file will need to be uploaded to the unit, this must
be the same file that is present on the server. If the tick box is left blank then the TLS
authentication procedure will be disabled.
•Proto: This drop down box is used to define which transmission protocol is to be
employed, UDP or TCP. OpenVPN is optimized for use with UDP however it is compatible
ARVOO Imaging Products B.V. page 15 of 33
Figure 9: Screenshot page "openvpn settings"

ITS101 Installation Manual
with TCP where UDP is not possible. It should be noted that in comparison to the UDP
protocol, when using OpenVPN, TCP will be less robust over congested or unreliable
networks.
•Cipher: This drop down box defines the encryption method is to be used. Several
methods are available.
•Enable LZO compression: Placing a tick in this tick box will enable the LZO (Lempel-Ziv-
Oberhumer) data compression algorithm. The compression mechanism is disabled by
leaving the text box blank.
Note: You must click on the apply button for any new settings to be implemented.
OpenVPN requires specific certificate files and keys to secure the connection between the
server computer and the ITS101. These will be specific to your installation and as such will
need to be uploaded to the unit.
•CA public certificate upload: The browse button is used to locate the Certificate
Authority (CA) certificate, CA.crt on your computer. This certificate is common to both
the server and the ITS101 unit. Once the file is selected, clicking on the send button
will initiate the transmission of the certificate to the ITS101 unit. A confirmation
message will be sent when the file has been uploaded (see next page).
•Client public certificate upload: The browse button is used to locate the client public
certificate on your computer e.g. client1.crt. This certificate file is unique to the ITS101
unit. Once the file is selected, clicking on the send button will initiate the transmission
of the certificate to the ITS101 unit. A confirmation message will be sent when the file
has been uploaded.
•Client private certificate upload: The browse button is used to locate the client private
certificate on your computer e.g. client1.key. This certificate file is unique to the ITS101
unit. Once the file is selected, clicking on the send button will initiate the transmission
of the certificate to the ITS101 unit. A confirmation message will be sent when the file
has been uploaded.
•TLS-auth file upload: The browse button is used to locate the TLS-authentication file on
your computer e.g. ta.key. This key file is common to both the server and the ITS101
unit. Once the file is selected, clicking on the send button will initiate the transmission
of the certificate to the ITS101 unit. A confirmation message will be sent when the file
has been uploaded.
3.3.1. Setting up an OpenVPN server
In this section we give an example on how to setup an OpenVPN server on Windows. A
working OpenVPN server is required in order to use the OpenVPN capabilities of the ITS101.
First download and install the OpenVPN package. You can find it on
http://openvpn.net/index.php/open-source/downloads.html. This installs the OpenVPN
package together with a Windows GUI.
Keys generation
Now OpenVPN is installed on your system you have to setup the keys to use. OpenVPN uses
OpenSSL to generate and sign the keys. OpenSSL can be downloaded from
http://www.slproweb.com/products/Win32OpenSSL.html.
To sign the keys we generate, we do need to have a Certificate Authority (CA). This can be an
official authority like VeriSign, but we can also sign our own certificates. To do this we have to
setup our own Certificate Authority. After that we can generate keys for our server and for
ARVOO Imaging Products B.V. page 16 of 33

ITS101 Installation Manual
every client we have. To make this all easy, OpenVPN comes with batch files which help us to
perform all steps.
Below follows step by step the generation of all keys.
•Open an command box
•Go to the easy-rsa directory (c:\Program Files\openvpn\easy-rsa)
•run init-config bat
•run vars bat
•run clean-all bat
•To build the CA run build-ca bat
•for the server :
•run build-dh bat
•run build-key-server bat <machine-name>
•for each client :
•run build-key bat <client-name>
Server setup
Now all keys are generated, we can setup our server. Below an configuration file is given.
Adjust this to your needs and save it with the keys in the c:\Program Files\openvpn\config
directory. Now you can start the server.
Configuration example:
# Which local IP address should OpenVPN listen on? (optional)
local 10.0.1.11 port 1194
# T P or UDP server?
proto udp
#This is key to configuring our bridge
dev tun0
#direct these to your generated files
ca /etc/openvpn/keys/ca.crt
cert /etc/openvpn/keys/server.crt
key /etc/openvpn/keys/server.key
dh /etc/openvpn/keys/dh2048.pem
ifconfig-pool-persist ipp.txt
#ensure the range of ip addresses you use in the last two arguments
# of this statement are not in use by either the DH P server or any other
# device on your internal network.

Client setup
Now the server is running you can upload the client keys and the CA public key to the ITS101
box and setup the right IP address. After that start the OpenVPN on the ITS101 and it should
connect to your server.

ITS101 Installation Manual
3.4. Ti e settings
In addition to the text string that forms the license plate recognition data, the date and time of
recognition are appended to the data. The time setting is also important for OpenVPN
connections as an incorrect time can lead to an OpenVPN connection being rejected.
The date and time can be set using the “ntp/time settings” page on the web service as shown
below.
The time and date on the ITS101 unit can be updated automatically using a Network Time
Protocol (NTP) server or it can be set manually should an internet connection not be available.
The ITS101 will use any internet connection available for connection to the NTP server.
•Server0, Sever1 and Server2: the ITS101 interrogates up to 3 NTP servers, the internet
addresses of these servers are to be placed into the text boxes provided.
•Date (dd-mm-yy): the current date can be entered into this text box, the date should
take the format of day, month, year.
•Time (hh-mm-ss): the current time can be entered into this text box, the time should
take the format of hours, minutes and seconds.
