Manual Installation Steps

If for some reason, you prefer not to use Plate Recognizer Installer, you can go through the steps below to manually install Stream with Docker.


Before proceeding further, be aware that there are two essential steps to fulfill in preparation for the setup process.

Install Docker

Install Docker and confirm that it's running.

If you have a Raspberry Pi, please follow this instructions to install docker

Docker Desktop on Windows

If using Docker Desktop on Windows with the legacy Hyper-V backend and not WSL2, make sure to check this box (next to C) for Resource File Sharing and the click “Apply & Restart”.

Step 2

Create Stream folder

  • Stream uses a single working directory at runtime that should not be ephemeral, it will contains extra configuration files and the processing outputs. It's mostly referred to as the Stream folder
  • The directory is specified as a volume mapped to /user-data and should be writeable. On your local system, specify a bind mount to make it easy to edit the configuration files.
  • The directory structure of the Stream folder will be generated the first time you run Stream. The main configuration file(config.ini) is also created at this time.

Create a Stream folder. For example:

mkdir c:\users\kyt\documents\stream


The next step involves detailing the procedures for manually installing Stream on various architectures. It is imperative that Docker be installed and operational for this stage.

List of Docker Images

There are Docker images for various architectures and engine customizations for some countries.

    • Specific version platerecognizer/alpr-stream:jetson-1.28.1-r32.6.1

Docker Command Selector

Use the selector below to generate your Docker command based on country, architecture, and operating system. The parameters for the License Key and Token can be obtained here.


Update the "Path to Stream config folder" field with the directory in which the "stream" folder was previously created.

Docker Command Generator




For the following commands:

  • Update directory bound to /user-data to your local directory. -v /path/to/my/folder:/user-data
  • --restart="unless-stopped" is included so Stream automatically restarts(upon system reboot or Docker restart) unless explicitly stopped. This works great when combined with the -d option so Stream runs in the background.

For the commands below, make sure to change XXXXX with your License Key and YYYYY with your Plate Recognizer Token. Get your token and license key.

Installation on Linux

In a terminal, run the following command:

docker pull platerecognizer/alpr-stream

To start the program, use docker run. If you are using Linux (Intel x86):

docker run --restart="unless-stopped" -t --name stream \
-v /home/kyt/documents/stream:/user-data \
--user `id -u`:`id -g` \

Installation on Windows

The following steps can be executed in the Command Prompt (cmd) or PowerShell. To open Command Prompt (cmd) or PowerShell:

Press Win + R to open the Run dialog. Type "cmd" for Command Prompt or "PowerShell" for PowerShell and press Enter. Alternatively, you can search for "cmd" or "PowerShell" in the Start menu and select the corresponding application.

Step 3

In Command Prompt or PowerShell, run the following command:

docker pull platerecognizer/alpr-stream
  #run stream using CMD
docker run --restart="unless-stopped" -t --name stream ^
-v c:\users\kyt\documents\stream:/user-data ^

Installation on Nvidia Jetson


Need some help? See our Jetson FAQ for technical questions and advanced configuration options.


When starting the container for the first time, it performs model optimizations that can last 5 to 10 minutes. Subsequent runs are fast.

In Command Prompt, run the following command.

docker pull platerecognizer/alpr-stream:jetson

If you are using a Jetson device, make sure to include --runtime nvidia --group-add video. The latest images are built for Jetpacks 4.6.1 and 5.1.1, using Stream with another Jetpack version may trigger errors. Otherwise, you can use older images.

docker run --restart="unless-stopped" --runtime nvidia -t --name stream \
-v /home/kyt/documents/stream:/user-data --privileged \
--group-add video --user `id -u`:`id -g` \

Having problems? Make sure to read the command selector tips.

Installation on Raspberry Pi

In Command Prompt, run the following command.

docker pull platerecognizer/alpr-stream:raspberry
docker run --restart="unless-stopped" -t --name stream \
-v /home/kyt/documents/stream:/user-data --privileged \
--group-add video --user `id -u`:`id -g` \

Having problems? Make sure to read the command selector tips.

Installation with Desktop GPU (Nvidia Only)

Make sure you have installed the right Nvidia drivers and have Nvidia-docker installed. Tested with drivers version 525.

Pull the gpu docker image:

docker pull platerecognizer/alpr-stream:gpu

Run the container with one of the following commands:

Option 1 (new version of nvidia-docker), notice the --gpus all:

docker run --restart="unless-stopped" -t --name stream \
--gpus all \
-v /home/kyt/documents/stream:/user-data \
--user `id -u`:`id -g` \

Option 2 (Deprecated nvidia-docker2 version):

docker run --restart="unless-stopped" -t --name stream \
--runtime nvidia \
-v /home/kyt/documents/stream:/user-data \
--user `id -u`:`id -g` \

Installation Using the Automatic Script

The provided shell script is tailored to facilitate the seamless setup and operation of an on-premise Stream on your system. This script dynamically verifies the presence of Docker and installs it if it is not already available.

Subsequently, the script orchestrates the configuration and launch of Stream, incorporating defaults. By default, it designates the script execution location as the foundational directory, creating a dedicated "stream" folder to house default configuration files and the outputs of the Stream.


  • Administrator permissions or membership in the docker group.
  • Supported system architectures: Linux Debian or Ubuntu (x86_64), Raspberry pi (armv7l, aarch64, armv7hf).

The Docker container instantiated by the script is denoted as "stream" and is configured to restart automatically unless intentionally halted. Additionally, the Stream is set up to commence automatically upon system boot, ensuring a seamless and persistent integration into your system environment.

Docker Image

The script pulls the Plate Recognizer Stream Docker image based on your system's architecture.

  • x86_64 architecture: platerecognizer/alpr-stream
  • ARM architectures (armv7l, aarch64, armv7hf): platerecognizer/alpr-stream:raspberry Running the Stream


Run the script with the following parameters:


If the parameters are not provided, the script will interactively prompt you to enter the token and license key.

Unique command:

Use the following command to download and run the script in one step. It facilitates the automation of installations in larger scripts or automated environments, such as virtual machine provisioning or containerized environments.

bash -c "$(curl -fsSL" -- -t=YOUR_TOKEN -l=YOUR_LICENSE_KEY

Example Usage:

bash ./ 

First Run

  • The first time you start Stream, a config.ini file is created in your Stream folder.
  • Now edit config.ini and change the url field. This can either be a video or an RTSP camera.

Check how to update the configurations.

Expected Output

When you run the command, you should get an output similar to this:

INFO:root:Plate Recognizer Stream v1.27.0
INFO:root:Loading detection zones.
INFO:root:Expires on 2022-01-07T06:55:00Z.
INFO:root:This license supports up to 20 camera(s).
INFO:camera-1:2021-09-02T18:10:07+00:00: Starting Camera One
