GeoVision – LPR Setup Guide

Configuring GeoVision LPR Software

In this guide, we will show you how to install and configure the GeoVision ASManager software, and also the LPR plugin on an existing GeoVision MultiCam system to allow license plate reading.

This guide assumes you already have a working version of GeoVision MultiCam software (GV-NVR, GV-1480, GV-800, etc.) on a computer and preferably an LPR camera connected as well.

Step 1: First, we will need to install a software suite called GV-ASManager. This software is actually the main Access Control software for all of GeoVision’s access control hardware. LPR functionality is part of this, and if configured correctly can even be used to read license plates and automate entry into gated areas.

To begin, either insert the AS Manager CD that came with your LPR USB Dongle or LPR camera and wait for the installer to load, and then continue to Step 3. If you did not purchase any of these or have lost the installation CD, you can navigate to this page on the GeoVision website and download the latest versions of the AS Manager software and LPR plugin. The LPR USB dongle and LPR Plugin will need to be installed on the DVR/NVR system running the GV-MultiCam/NVR software. You might also need to download and install the DirectX End-User Runtimes (November 2008).

Step 2: After downloading both of the install files, extract them and then launch the setup for each one. Make sure to quit all currently running GeoVision software before attempting to install. Follow all directions on screen to install both AS Manager and the LPR USB Dongle plugin (to be installed on computer with GV-MultiCam/NVR. You may be asked to restart your computer.

Step 3: If you are installing from the installation DVD, use these steps to install the system properly:

1. Insert the USB Dongle to your computer.

2. Insert Software DVD to your computer and a window will pop up automatically.

3. Select Install or Remove GeoVision GV-Series Driver and click Install Geovision USB Devices Driver.

4. If you don’t have DirectX 9.0c installed in your computer, select Install DirectX 9.0c.

5. Select Install DirectX End-User Runtimes (November 2008).

6. Select Install Microsoft .NET Framework Version 3.5.

7. Select Install GeoVision Access Control System, click GeoVision Access Control System and follow on-screen instructions to complete the installation.

Step 4: The first time you launch the AS Manager software, you will be prompted to create a default administrator account. You will also be prompted to input an email address, where password information can be sent in the event of a forgotten password.

Step 5: If this is the first time installing GV-ASManager, you will be presented with the Database Tools window and prompted to create a new database for the LPR plate reads. You will need to choose the “ASManager Database Setting” option.

Step 6: Next, choose the option labeled “Setup MDB/ MSSQL Database for ASManager“.

Step 7: From the Setup Database Connection window, choose the first option, Microsoft Office Access Database as your database type. It is recommended by GeoVision to use this database format.

Step 8: In the next window, you will be shown the process of the database connections being created, and for every connection that does not exist you will be prompted to confirm creating a new one. Make sure you choose “Yes” for all database connections being created (ASConfig, ASLog, ASLPR & ASPatrol).

Step 9: If all of the database connections have been created correctly, you will see the following screen. Click on the Exit button to continue.

Step 10: You should now be prompted again to input your ID/Username and Password. If you want to configure the software to automatically log in every time you start the software with your login information, make sure the “Auto login” option is checked.

Step 11: The GV-ASManager software can allow remote connections to search for license plates or even allow access to doors and locks. To enable this function, you will have to allow the GV-ASManager program access through the Windows Firewall by clicking on “Allow access” for every firewall prompt. If you do not want to enable this function, make sure you click on the “Cancel” button for every Windows Firewall prompt.

Step 12: On the computer that is running GV-MultiCam/NVR with the LPR USB Dongle inserted, and also with the LPR plugin successfully installed, launch GV-MultiCam. Once the software has started and you have successfully logged in with a Power User or Supervisor account, click on the Configure button, then select the Advanced Video Analysis menu option and then select the License Plate Recognition option. If you do not see this option, then the LPR plugin has not been successfully installed and you will need to attempt the installation again. From this menu, make sure you select both Auto Start LPR Service and Auto Start Overview Camera Service. If you would like to test that they automatically start when GV-MultiCam is started, restart the MultiCam software and navigate back to this menu. You should now see that Enable LPR Service and Enable Overview Camera Service are enabled (checkmark next to each option). Once both services are running, we can go back to the GV-ASManager window.

Step 13: Once you are in the GV-ASManager software, we will need to add the MultiCam/LPR server. From the menu bar, click on Setup and then click on Devices.

Step 14: In the Device List window, click on the + button on the right hand side to start adding an LPR device. When prompted with the “Please Enter ID” window, just leave default options selected for ID and Name, unless you would like to choose your own name for the LPR system you are adding. For Type, if you are adding a GV-MultiCam system with the LPR plugin, make sure to select “PC LPR“. If you are adding a GV-DSP LPR or GeoVision LPR camera with integrated LPR functions, then choose “Standalone LPR” as your LPR Type.

Step 15: In this LPR Setup window is now where you will enter information about your LPR server so that GV-ASManager can log into the GV-MultiCam/NVR software to start analyzing license plate information. To enter in the proper information, you have a few options:

  • If the GV-ASManager software was installed on the same computer as the GV-MultiCam/NVR software, you can use for the IP Address, and then use your credentials from the GV-MultiCam/NVR software for the User and Password.
  • If the GV-MultiCam/NVR software is running on another computer, you can first click on the magnifying glass next to the IP Address field and let the system search for the DVR/NVR on the network. Choose your DVR/NVR server if you find it on the list. If the scan does not find your server, you can manually enter in the IP address of that computer and then your User and Password information.

Step 16: If you have entered in the correct credential information in the LPR Setup window, you can use the Sync from DVR-LPR button to correctly pull in all available LPR lanes for analysis. Click on the Sync from DVR-LPR button and then enter in the IP address you had entered in the main LPR Setup window. Leave the Command Port as the default (3388), or change it to the current Command Port your GV-MultiCam/NVR system is using. Then click on the Sync button. If successful, you will see that the camera list in the Connection section will now show the correct number of cameras.

Step 16: Once you have synchronized available camera information, you can now configure each lane/camera that will be analyzing license plates. In the tabs near the top of the LPR Setup window, you will see a tab for each of up to 8 lanes of LPR recognition. Using the image to the left you can configure the following:

A. In this area, you can enable recognition and then name the lane of recognition (e.g. Main Entrance, Exit, South/North/East/West Entrance…)

B. In this area, you can assign a certain camera from your GV-MultiCam/NVR install to be assigned to a specific lane. For example, if you were going to use camera/channel 5 from your GV-MultiCam/NVR install for LPR use, you would choose “Camera 5” from the drop-down  menu for Recognition Camera. If you happen to have a wide-angle camera also pointed at the area where vehicles are monitored, you can assign it as the Overview Camera so that when the LPR system recognizes a plate number, it can catalog not only the plate itself but also a snapshot from the overview camera.

C. In this section, make sure to choose the correct driving direction, either Incoming (vehicles moving towards camera) or Outgoing (vehicles moving away from camera). Leave Recognition as the default of “By motion detection“, unless you are integrating a sensor at the area where cars are stopping. You can experiment with the different options available for Matching Mode and also different Sensitivity levels until you find a balance that works best for you.

D. In the Recognition section, by default the system will use the whole video frame to try to scan for plates. You can use either the + or selections to modify the area where you might want to narrow down the plate reads. For example, in the image to the left, we removed some of the top and bottom of the video frame from being used to recognize the plates. This can sometimes be useful if there might be other sources of letters or numbers coming into the video frame that you might want to ignore.

You will need to configure these options for each of the lanes you are trying to add to the system, with there being a maximum of 8 lanes of LPR. When you feel you have configured all options, click on the OK button on the lower right of the window.

Step 17: If you have successfully added the LPR system to GV-ASManager, you should see it listed in the LPRs column.

Step 18: In order to see a real-time display of plates being read, we will need to open up an LPR monitoring window. Click on Monitoring from the menu bar, and then select New LPR Monitor.

Step 19: In the LPR Monitor window, you should start seeing plate reads when the system detects a license plate. You will see information such as what lane the plate read came from, and what it recognized the plate as. From the tabs at the bottom, you can choose to view these readings in text form or with a snapshot of the plate read for verification.
