2GETTING STARTED

2.1 MOUNTING THE ANPR

Determine how to mount the ANPR. Onto a pole or behind the barrier. Mount behind the barrier to ensure

recognition right in front of the barrier.

Importantmounting issues are:

•Best focus distance is between 3 and 6 meters.

•Angle between ANPR and number plate should be smaller than 25 degrees.

Mounting details are described in chapter 3.

2.2 CONNECTING THE ANPR

The ANPR is delivered with 5m cables for power, I/O and network. Power supply, RS485 communication and I/O

are combined in one cable. Ethernet network is a second cable. The cables are pre-fitted to the ANPR. For

installation the ANPR does not need to be opened.

Connectingthe power supply and network cables are requiredto configure the ANPR.

Connection details are described in chapter 4.

2.3 ASSIGNING AN IP-ADDRESS

Enterthe default IP-address in the address bar of your web browser.

Default IP address is:

IP address: 192.168.0.21

The login window appears where the useris asked to type the username and password.

Username: superuser

Password: superuser

Go to the system configuration and setup the network configuration as desired. If required, now also other

configuration settings may be changed.

Details about network settings are described in chapter 5.3.1.

2.4 TESTING THE ANPR

Test the ANPR to check if it isaligned correctlyand if itis able to readthe license plates.

Drive the vehicle into the positionwhere it should be possible to read its license plate.

Connect to the ANPR using your web browser and select the 'Camera OCR' feature. On the left side of the page

'live' video images are shown and also the license plate reading results. It might be necessary to adjust the ANPR

alignment.

3INSTALLATION

3.1 SAFETY PRECAUTIONS

The followingsafety precautions mustbe observed duringnormal use, service and repair.

•The ANPR shall be connected to safety ground.

•Disconnectthe power supply before removingany parts.

•The ANPR shall only be installed and serviced by qualified and trained personnel.

•To be sure of safety, do not modify or add anything other then mentioned in this manual or indicated by

NEDAP N.V.

•CAUTION: for continued protection againstrisk of fire, replace fuses onlywith the same type and rating.

•The ANPR can be powered from a low power, Class 2 powersupply, incompliance with local regulations.

•The ANPR is equipped with an 850nm Infrared illuminator. The human eye will not or slightly see this light

coming from the illuminator. Do not look into the ANPR lens directly from close range or for more than 100

seconds. Eyes can be damaged by not taking these precautions. During normal use of the ANPR at a vehicle

gate,reading plates,there is no risk to the public.

3.2 MOUNTING

The ANPR is intended for vehicle access control. Vehicles are identified by the number plate when approaching

the gate. Because the number plate recognition is very fast, a full stop is normally not necessary. The ANPR

covers a reading distance of 3 to 6meters.The field ofview is typically one lane wide.There are 2 recommended

positions for the ANPR.

Pole mounting

The ANPR is positioned directly behind or in front of the actual barrier onto a pole. In that case the ANPR can be

best positioned on a pole at maximum 2m20 height. In this position the number plate of the vehicle directly in

front of the barrier cannot be read anymore. So these vehicles need to be recognized in flow. Mounting the

ANPR at 2m20 height is here the best option. When overhead installation is an option, the ANPR can at best be

installed inthe center ofthe lane, above the lane. Horizontal angle will be 0°in that case, whichis good.

Figure1: Pole mounting

ANPR

Behind barrier mounting

The ANPR is positioned behind the barrier at bumper height.

If there is space behind the barrier and the sight is not blocked, then the best place for the ANPR is at bumper

height (0.5mheight) about 2 to 3 meters behind the barrier. Avehicle justin front ofthe barrier is still recognized

in that case.

5CONFIGURATION

5.1 USING THE WEB SERVER

Prior to accessing the ANPR using a Browser, make sure the PC network configuration is coherent with the IP-

address of the device to access. E.g.: if the ANPR IP-address is 192.168.0.21, the PC in use should have assigned

an IP-addressbelonging to the same class (e.g.192.168.0.22). See also chapter 2.3 for details about how to assign

an IP-address to the ANPR.

Figure5: Using theweb server

Enter the IP-address (or NetBiosName) in the address bar of your web browser.

The login window appears where the user is asked to type the username and password.

Factory default username and password are:

Username: superuser

Password: superuser

Note: It is recommended, tochange the factory defaultusername andpassword after installation. See chapter 5.3.2.

If the login was successful, the user is now able to access the main menu screen. The main page shows two

sections: Plate Reader and System. Referto chapters 5.2 and 5.3 for furtherdetails.

5.2 NUMBER PLATE READER CONFIGURATION

5.2.1 GENERAL

The ANPR systemcan operate in three differentmodes:

•FREE RUN mode

•TRIGGER by digital input mode (see chapter 5.2.4 about how to setup the digital input to trigger the ANPR).

•TRIGGER by ethernet mode (see the ANPR ethernet programmers guide about how to trigger the ANPR by

ethernet).

When in FREE RUN mode, the ANPR freely grabs and processes images. The software automatically detects the

presence of a number plate in the image and thus generates events.

When in TRIGGER-START-STOP mode, the ANPR grabs and processes the images in the time period between the

start trigger and the stop trigger. In case the stop trigger is not being activated within the GateTimeMax interval,

the system automatically generates the stop trigger after the interval expires. Any stop trigger received prior to a

start trigger will be ignored. Any start trigger received after a start trigger immediately generates an event and

restarts the image processing.

When in TRIGGER-START-TIME mode, the unit starts image grabbing when the start trigger is activated and stops

image grabbing after a time interval that was previously defined in the GateTimeMax setting (see chapter 5.2.4).

Once GateTimeMax has expired, an event is generated. If the system receives a start trigger during GateTime

period, it immediatelygenerates an event and restarts the image processing.

When in TRIGGER-START-FREE-RUN-STOP mode, the unit starts image grabbing when the start trigger is

activated and then starts grabbing and reading number plates in FREE RUN mode. The system may generate

multiple events during the interval betweenstart trigger andstop trigger.

When in TRIGGER by ethernet mode the image grabbing and processing is started upon receiving the start

TRIGGER message from the Ethernet network. The start trigger message contains a precise time in milliseconds

thatexpresses the GateTime during whichthe ANPR will grab images. When GateTime expires or upon receiving

a stop trigger message, the machine stops image grabbing. The trigger message also contains a generic string

the system uses to generate trigger messages where info may be inserted. Such string will later made available

on the web interface using the %NET_TRIG_ID tag. This makes it possible to associate to any event data, images

and other info aboutthe specific trigger message from which theywere originated.

The system maygenerate the following events upona processed image:

•OCR READ

•OCR NOT READ

•OCR NO PLATE (not in FREE RUN mode)

The General Settings page contains the following configurationfields:

Enable Engine: It allows enabling/disabling the processing of the images grabbed by ANPR. The

parameter takes two possible values: YES orNO. If set to NO, the device is switched to

stand-by mode and its infrared illuminator is disabled. It will ignore any external

trigger. The infrared illuminator is only momentarily enabled if the Camera OCR page

is being accessed.

Acquisition mode: It allows selecting the system operating mode. Select FREE-RUN, TRIGGER-START-

STOP, TRIGGER-START-TIME, TRIGGER-START-FREE-RUN-STOP or TRIGGER-ETHERNET.

Site Address: This field can contain an alphanumeric string, such as the address of a system

location. This string is available as %SITE_ADDRESS TAG and can be sued in the text

value field of the Save Image action.

TCP message after ftp actions: With this parameter you can enable sending a TCP message after ftp actions

(ftp save image and ftp save DB).
