Introduction

This guide describes how a Tattile camera can be connected to BVMS. We recommend keeping the Tattile camera documentation and BVMS configuration manual at hand to fine tune the system configuration to the specific needs of your project.

Configuration

This guide helps you to configure three aspects:

1. Match list configuration: the Tattile cameras can load a license plate match list from an FTP server. This guide describes how you can enable an FTP server on the BVMS management server and use this as a source of the license plate match list.
2. Camera configuration: the Tattile camera itself requires specific settings before it can be added to BVMS.
3. BVMS Configuration: adding the Tattile camera to BVMS.

Check list configuration

Tattile cameras can have up to two check lists: A and B. This guide helps you to configure check list A based on an FTP server running on the BVMS management server. The guide is written based on Windows Server 2019 but can also be used Windows Server 2016 and Windows Server 2012 R2 as they look and feel similar.

Setting up an FTP server on the BVMS management server

Open the Internet Information Services Manager and add an FTP site to the local server.

You can give the FTP site an arbitrary name. The physical path needs to be accessible for a user with both read and write access on the file system as well as via the FTP site.

The FTP site should not be configured with SSL. The other settings can be adjusted based on the security-level of the installation. The security-level can be increased by applying, for example, IP filtering on the FTP site or in the Windows Firewall. This way, only configured cameras can access the FTP site.

The FTP site uses Basic authentication. This means that the FTP authentication uses the Windows authentication mechanisms in the background. Users (cameras) should only have read access on the FTP site. This prevents unauthorized modifications of the match list.

Use the computer manager to create a special user, for example, "ftp_user". This user should have read and write access on the FTP site folder and on the file system.

Create a file in the FTP site, for example, BlackList.txt using Notepad. Save the file using UTF8 encoding:

The contents of the file should match the following format:

License plate;Country;Comments

Please be aware that the Country identifier always consists of three letters.

### can be used as a wildcard and represents all countries.

AB134HK;ITA; 
Test BS46588;###; Substitute car 
RS054HG;ITA; President’s car

Test if you can open the file using your favorite browser by entering the FTP address: ftp://ftpuser:password@x.x.x.x:21/BlackList.txt. The username and password dialogue should not pop-up and you should have direct access to the content of the BlackList.txt file.

Synchronizing the check list in the camera with the FTP server

Plate Reader => Check List => Check List A

You should enable check list A and configure the List Location as FTP. The FTP IP should match the location of the IP address from the BVMS management server. The File Name should match the name of the file storing the check list.

When you click Reload List, the List Loaded message should appear, including the number of license plates you have put on the list.

Multiple cameras can point to the same check list. The checklist can also be generated by an external application that writes the file considering the required format.

Configure match list management from BVMS Operator Client

BVMS operators can manage the check list from the BVMS Operator Client. The user account the operator uses to login to Windows needs to have read and write access to the file that the FTP server hosts. You can achieve this by creating a new shared folder or by using the existing (hidden) shared folder. In the example below we use an existing (hidden) share folder: c$.

Use the BVMS configuration client to open the resource manager.

Add a new resource, in our case, an external application.

The external application launched notepad.exe and points to the location of the check list using an argument.

Add the external application to the BVMS logical tree. This way operators can access it when they want to adjust the check list. Of course you can also put the external application in a folder.

Tattile Vega II (Stark) - Camera configuration

1 Network configuration

System settings -> Network
Ensure that the camera is part of the same network as your BVMS system.

System settings -> Services
Enable the HTTPS port 443 on the device.

2 Add User Group/User

Either use the default user and change the default passwords or add an additional admin user that BVMS can use to login to the camera.

User -> Groups
Create a new user group that has the required permissions.

User -> Users
Create a new user e.g. "admin"

3 Configure Hosts & Secrets

Hosts & Secrets -> Hosts
Add the IP address from the BVMS management server as a new Host to the camera.

Hosts & Secrets -> Credentials
Add new credentials in the camera.
IMPORTANT: Credentials must match exactly to the given parameter here (case sensitive).

4 Configure messages, events and actions settings

The Tattile camera offers several messages, events and actions. To be able the receive events in BVMS corresponding entries have to be created.

4.1 Messages
Output -> Messages
For BVMS two message must be created which must exactly match the given pattern here (case sensitive).

A) BVMS Plate Detection JSON

{
   "plate_string": "${TRANSIT.PLATE_TEXT}",
   "event_type": "Ocr Read",
   "country_code": "${TRANSIT.PLATE_COUNTRY}",
   "event_date": "${VIRTUAL.DATE}",
   "event_time": "${VIRTUAL.TIME}",
   "serial_number": "${DEVICE.SERIAL_NUMBER}",
   "device_sn": "${DEVICE.SERIAL_NUMBER}"
}

B) BVMS Plate Identification JSON

{
   "plate_string": "${TRANSIT.PLATE_TEXT}",
   "event_type": "Match On List A",
   "country_code": "${TRANSIT.PLATE_COUNTRY}",
   "event_date": "${VIRTUAL.DATE}",
   "event_time": "${VIRTUAL.TIME}",
   "serial_number": "${DEVICE.SERIAL_NUMBER}",
   "device_sn": "${DEVICE.SERIAL_NUMBER}"
}

After this you must have two messages configured.

4.2 Actions
Output -> Actions
The camera will only send the message if an action is specified. For BVMS you need two actions configured.

A) BVMS Send Detected
Action must contain:

• Destination: Select configured host
• Authentication: This must be set to "Basic" and select the configured credentials "BVMS-Credentials"
• Body: Select the "BVMS Plate Detection JSON" message to be send.
  

B) BVMS Send Identified
Action must contain:

• Destination: Select configured host
• Authentication: This must be set to "Basic" and select the configured credentials "BVMS-Credentials"
• Body: Select the "BVMS Plate Identification JSON" message to be send.
  

After this you must have two actions configured.

4.3 Events
Output -> Events

Under Events you must now specify the action that shall be executed for the event and under which conditions.
For BVMS two Events need to be specified:

A) BVMS Detected

Select the "BVMS Send Detected" action as main action.
Enable the filtering and select "All conditions".
For Predicates add the "DATALOOKUPMATCHED@<your list name>" with the value "is False".
This will trigger an event for plates that are not in the list of known number plates.
For DATALOCKUP configuration refer to chapter 6.

B) BVMS Identified

Select the "BVMS Send Identified" action as main action.
Enable the filtering and select "All conditions".
For Predicates add the "DATALOOKUPMATCHED@<your list name>" with the value "is True".
This will trigger an event for plates that are part of the list of known number plates.
For DATALOCKUP configuration refer to chapter 6.

5 Plate Recognition
Anpr -> Plate recognition
Optionally you can configure a separator plate for specific countries. This determines how the detected license plates are written into the BVMS logbook. The camera user manual contains more information.

6 DataLookup
Anpr -> Data Lookup
To be able to identify number plates you have to specify a source file, this can either be local on the camera or remote on an FTP.
The alias name of the given source will be used in the filtering of the Events described in chapter 4.

Tattile Vega - Camera configuration

This chapter explains how to configure previous generation of Tattile cameras to BVMS.

Add user

System => HTTP Users

Change the default usernames and passwords or add an additional admin user that BVMS can use to login to the camera.

Configure communication protocol

System => Protocols => VRC

BVMS communicates with the Tattile cameras using a secured protocol (VRCS). Configure the VRC server settings as indicated in the image below.

System => Network

Configure the IP address from the BVMS management server in the Static hosts section. The Names must state BvmsLpr_Server (case sensitive).

Configure event and action settings

Plate Reader => Events Actions

The Tattile camera has several events and actions. We use two events: Ocr Read and Match On List A. Configure the Template Message for these events by clicking on the image.

You should configure both events in the same way using the example below. The Server name/IP must state BvmsLpr_Server.

The Text Value should state:

%EVENT_DESC%PLATE_STRING%PLATE_COUNTRY%SN%UTC_DATE%UTC_TIME

Apply the changes.

Plate Reader => Events Actions => Template Configuration (Config, bottom of the page)

Additionally, you need to upload a template message. Click the Upload Page and load the file C:\Program Files\Bosch\VMS\Appdata\LPR_Event_Template.txt on systems where the BVMS configuration client is installed.

Configure separator plate

Optionally you can configure a separator plate for specific countries. This determines how the detected license plates are written into the BVMS logbook. The camera user manual contains more information.

 Be aware that the time server must be registered in the camera so that the alarms are displayed with the correct time in the BVMS.

BVMS configuration

The BVMS configuration manual also describes how to add LPR devices to the BVMS configuration.

Add LPR camera

Add an LPR device by right clicking on the LPR devices node.

Add video (RTSP) camera

Some Tattile cameras also have a video output (Not possible for the basic family). You can add these cameras to the Video Streaming Gateway (VSG) configuration as an RSTP camera.

Use the rstp://x.x.x.x without authentication to load the video stream into BVMS.

Configure LPR events

You can use the Events and Alarms tab in the BVMS configuration client to configure the events and alarms. BVMS receives License plate detected (Ocr read) and License plate identified (Match On List A) from the camera.

We recommend to configure an alarm on the License plate identified event and store the License plate detected event in the BVMS logbook.

Allow only users in the "Admin" group to manage license plates

Some user groups might not be allowed to edit the check list. You can remove the rights by de-selecting the node in the logical tree on the User groups tab in the BVMS configuration client.

Operation

Alarms from the camera are processed using the normal BVMS alarm management. The check list can be easily edited by an operator by dragging and dropping the Manage License Plates application into an image pane, editing the file, and saving it (either by CTRL+S or by clicking File / Save).

Alarm Handling

If the License plate identified or License plated detected events are configured to trigger alarms,  the following information will be displayed in an alarm:

• The standard BVMS alarm information as timestamp, event type, alarm title, triggering device, etc.
• The license plate itself
• The country identified (DEU for Germany, etc.)

Investigation / Reporting

With the LPR events License plate identified  and License plate detected stored in the BVMS logbook, it is possible to solve use cases as "When did a car enter and leave the premises".

Open the logbook search in the OperatorClient, define a search filter for the License Plate detected or License Plate identified event and run the search, if you want to get an overview of all detected plates. If you look for a specific number plate, you can additionally enter the license plate in the Text Data field.

The results are listed below and can be exported using the Save results button.
