# Shinobi Motion Detector
|
||||
|
||||
Install required libraries.
|
||||
|
||||
**Ubuntu and Debian only**
|
||||
|
||||
```
|
||||
sudo apt-get install libcairo2-dev libjpeg-dev libpango1.0-dev libgif-dev build-essential g++
|
||||
```
|
||||
|
||||
**CentOS only**
|
||||
|
||||
```
|
||||
su -c 'yum install cairo cairo-devel cairomm-devel libjpeg-turbo-devel pango pango-devel pangomm pangomm-devel giflib-devel'
|
||||
yum search arial
|
||||
yum install liberation-sans-fonts.noarch
|
||||
```
|
||||
|
||||
**Install the Node.js Canvas engine**
|
||||
|
||||
```
|
||||
sudo npm install canvas
|
||||
```
|
||||
|
||||
Go to the Shinobi directory. **Below is an example.**
|
||||
|
||||
```
|
||||
cd /home/Shinobi
|
||||
```
|
||||
|
||||
Copy the config file.
|
||||
|
||||
```
|
||||
cp plugins/motion/conf.sample.json plugins/motion/conf.json
|
||||
```
|
||||
|
||||
Edit it the new file. Host should be `localhost` and port should match the `listening port for camera.js`.
|
||||
|
||||
```
|
||||
nano plugins/motion/conf.json
|
||||
```
|
||||
|
||||
Start the plugin.
|
||||
|
||||
```
|
||||
node plugins/motion/shinobi-motion.js
|
||||
```
|
||||
|
||||
Or to daemonize with PM2.
|
||||
|
||||
```
|
||||
pm2 start plugins/motion/shinobi-motion.js
|
||||
```
|
||||
|
||||
Doing this will reveal options in the monitor configuration. Shinobi does not need to be restarted when a plugin is initiated or stopped.
