OpenALPR Milestone Plugin
- The OpenALPR Milestone Plug-in integrates OpenALPR data with Milestone XProtect.
How it works
- OpenALPR software reads video directly from a camera stream, analyzes the video, produces JSON data containing plate information, and posts this to a local beanstalkd queue
- The Milestone Plug-in contains two components:
- A Windows service that runs in the background. It constantly reads from the queue and posts the data to Milestone XProtect
- A Milestone plug-in that is located inside XProtect that is used to display the results to users
- The Windows service sends two types of data to Milestone XProtect
- All recognized license plates are saved as Milestone Bookmarks
- Any plates that match an alert list (managed as a CSV spreadsheet) are saved as a Milestone Alarm.
The OpenALPR software must be licensed with a commercial key, the Milestone XProtect Plugin simply requires a Milestone license to operate.
OpenALPR software requires sufficient CPU to recognize license plates. We recommend a desktop/server class Intel PC with at least 1 CPU core per LPR camera stream being actively analyzed.
In order to use the bookmarks feature (to search plates within Milestone) you must have at least Milestone XProtect Professional+
- Download and install the OpenALPR On-Premises Agent on the same machine that is running Milestone XProtect
- Request a license code here: https://license.openalpr.com/evalrequest/
- Setup the OpenALPR software to use the data destination "Local Queue"
- Add your LPR camera to OpenALPR
- Once this is complete, you should see the license plates being read in the user interface as vehicles drive past the camera
- Install the OpenALPR Milestone Plugin using the installer
- Open Milestone XProtect and click on the "OpenALPR" tab
- Click on the Camera Mapping, and ensure that the OpenALPR camera is properly associated with the milestone camera. If not, you can click the drop-down to manually associate the two cameras
- As new plates arrive you will be able to search them in Milestone.
The OpenALPR Milestone plug-in can also create Milestone alarms based on a list of plates that you provide. This is managed as a simple spreadsheet.
- On the "OpenALPR" tab of Milestone XProtect, click "Edit Alarms"
- The file will open as a spreadsheet using Excel or a text editor
- Add all the plate numbers that you wish to alert. Click Save (overwriting the file), and make sure you keep the "CSV" format.
- The OpenALPR plug-in will automatically detect the changes to the CSV file and begin alerting on the plates in the list.
- Download Visual Studio 2017
- Install .NET Framework 4.6.2 https://www.microsoft.com/net/download/visual-studio-sdks
- Install NSIS (for packaging the installer)
- Open the project, and switch to "Release" and "x64" mode (Build -> Configuration Manager)
- If you wish for every build to automatically copy the binaries to your local Milestone system:
- Copy the "Solution build referenced files\BuildRequirements*.bat to your build folder"
This plug-in uses the NSIS installer to create a Windows installer package. The nsi file is included in this repo in the installer directory.
