[OpenAlpr](http://www.openalpr.com/) integration for Home Assistant allows you to process licences plates from a camera. You can use them to open a garage door or trigger any other [automation](https://home-assistant.io/components/automation/).

### {% linkable_title Local installation %}

If you want process all data local you need the command line tool `alpr` in version > 2.3.1

If you don't find binaries for your distribution you can compile from source. Documention of how to build openalpr is found [here](https://github.com/openalpr/openalpr/wiki).

On a debian system you can use this cmake command to build only the command line tool (which second part on linux build instruction - ubuntu 14.04+):
```bash
cmake -DWITH_TEST=FALSE -DWITH_BINDING_JAVA=FALSE --DWITH_BINDING_PYTHON=FALSE --DWITH_BINDING_GO=FALSE -DWITH_DAEMON=FALSE -DCMAKE_INSTALL_PREFIX:PATH=/usr ..
```

Verify your alpr installation with:
```
wget -O- -q http://plates.openalpr.com/h786poj.jpg | alpr -
```
