Page 3: Introduction
ANPR 1 INTRODUCTION The NEDAP ANPR License Plate Reader offers automatic number plate reading. The NEDAP ANPR is an all in one camera including camera, analyzer and IR illuminator. The ANPR has embedded processing software onboard. The License Plate Reader is default featured with an RS485 and Ethernet communication. Wiegand is possible using the separate available Wiegand Interface Module. -
Page 4: Getting Started
Drive the vehicle into the position where 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. -

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. -
Page 6: Dimensions
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 (0.5m height) about 2 to 3 meters behind the barrier. A vehicle just in front of the barrier is still recognized in that case. - Page 7 ANPR 60° max 60° max Figure 4: Mounting bracket dimensions © Nedap AVI, P.O.

Page 8: Connections
The ANPR is delivered with two 5m long cables. 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. -
Page 9: Configuration
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-address belonging 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. -

Gain0/Shutter0, Gain1/Shutter1, Gain2/Shutter2 and Gain3/Shutter3. Too light or too dark images are automatically excluded from processing by the ANPR software. Set values must be steady crescent. This means that Gain3 ≥ Gain2 ≥ Gain1 ≥ Gain0 and Shutter3 ≥ Shutter2 ≥... -

PLATE READER The ANPR system is capable of real time OCR processing grabbed images. Up to 4 countries number plates can be simultaneously read. It is necessary to update the ANPR firmware if the user wants to change the countries the system should read. - Page 13 If set to 0 (zero), the reading is valid only if the ANPR recognizes every character of the number plate. If set 1 or 2 (maximum value), the ANPR will consider the reading valid while the unrecognized characters are replaced by a Jolly character –...

Page 14: Digital Trigger
5.2.4 DIGITAL TRIGGER This page configures the digital input to trigger image processing on the ANPR system. When the ANPR is configured to FREE RUN mode, the settings below are ignored. The Digital Input Trigger page contains the following fields: Start Input Num: Set the number of the digital input associated with the start trigger. -
Page 15: Check List
5.2.5 CHECK LIST The ANPR features 2 check lists called A and B. The configuration of check list A and B are identical. These check lists can also be referred to as a white-list or black-list. These check lists can be stored either on the internal flash memory of the ANPR or on a remote ftp-server. The check list is loaded into RAM memory upon ANPR start-up. -
Page 16: Events / Actions
5.2.6 EVENTS / ACTIONS The ANPR generates a number of different of events. It is possible to associate one or more actions to each event. The Events and Actions matrix is used to configure and assign actions to the events. - Page 17 ANPR 5.2.6.1 ACTION: SAVE IMAGE TO FTP SERVER This function allows saving the images of vehicle detected by the ANPR to a remote ftp- server. See chapter 4.1 for details about connecting the ethernet interface. Enable: Select YES to enable save to an ftp-server.
- Page 18 If enabled, this feature allows creating and automatically updating on a remote ftp-server a text file in CSV format (CSV = Comma Separated Values) containing information about every detected vehicle by the ANPR. See chapter 4.1 for details about connecting the ethernet interface.
- Page 19 If enabled, this action will send a message to a TCP/IP socket connection. Tags are used to define the content of the message sent. See chapter 4.1 for details about connecting the TCP/IP ethernet interface. See the ANPR ethernet programmer's guide which describes the TCP/IP message data format. Enable: Select YES to enable sending messages to a TCP/IP socket.
- Page 20 The packet data contains the tags defined in the Message field. Every tag is defined by a tag-identifier and a tag- size indicator. The packet may contain any number of tag-fields. Tag-fields are arranged depending on the ANPR firmware. This may as well change when using a different firmware version. For this reason, when searching for tag-fields in a received packet, the server should scan all tag-fields regardless of their position inside the received message.

5.3.4 FIRMWARE It is possible to update the ANPR firmware. The firmware update requires one file only, where operating system, application and configuration files are integrated. The firmware file is distributed as a .bin-file. Two possible update options are available: Upgrade firmware keeping current settings. -
Page 24: Device Info
Press the Download-button to save a compressed bin-file containing the ANPR firmware and all its user defined parameters. This feature is very useful when duplicating the same configuration onto another device or keeping the file for backup purposes. The bin-file can be directly loaded to an ANPR system, using either of the available upgrade options. -
Page 25: Sys Statistics
5.3.7 SYS STATISTICS This page contains the statistics about data sending from ANPR to external devices. The info in this page is very useful upon installation as they help check the available bandwidths from ANPR to the data receiving servers. -
