In the past month I was thinking about way to integrate USB webcams into Home Assistant again. The main reason was that this would give those devices a second life and enable one to benefit from low-cost video surveillance. There are a couple of options available like <a href="http://www.pygame.org/hifi.html">pygame</a> or <a href="http://www.simplecv.org/">SimpleCV</a> but I never finished something. With the <a href="https://home-assistant.io/components/camera.local_file/">Local File camera platform</a> by <a href="https://github.com/Landrash">Landrash</a> and <a href="http://lavrsen.dk/foswiki/bin/view/Motion/WebHome">motion</a> you could integrate a local USB webcam with a few very easy steps.</p>
<p>In this blog post I using a Fedora 24 (will most likely work on other distributions too) installation with Home Assistant 0.22.1 on a Foxconn nT-330i with an old <a href="http://support.logitech.com/en_us/product/quickcam-sphere-af">Logitech QuickCam Orbit AF</a> and a <a href="http://support.logitech.com/en_us/product/hd-webcam-c270">Logitech HD Webcam C270</a>. As a start only the Quickcam is used. No multi-camera setup for now.</p>
<a name="read-more"></a>
<p>Check first if the your operating system lists your cameras.</p>
<div class="highlighter-coderay"><div class="CodeRay">
<div class="code"><pre>$ lsusb
[...]
Bus 002 Device 016: ID 046d:08cc Logitech, Inc. Mic (PTZ)
[...]
</pre></div>
</div>
</div>
<p>The camera we are going to use is available at <code>/dev/video1</code>. The C270 is the one on <code>/dev/video0</code>.</p>
<div class="highlighter-coderay"><div class="CodeRay">
<div class="code"><pre>$ ls -al /dev/video*
crw-rw----+ 1 root video 81, 0 Jun 23 08:05 /dev/video0
crw-rw----+ 1 root video 81, 1 Jun 23 08:36 /dev/video1
</pre></div>
</div>
</div>
<p>We need an additional software part to handle the cameras. <a href="http://lavrsen.dk/foswiki/bin/view/Motion/WebHome">motion</a> is capable of monitoring the video signal from USB and network cameras, do motion detection, and other nifty stuff like saving images, add text, or basic image manipulations.</p>
<div class="highlighter-coderay"><div class="CodeRay">
<div class="code"><pre>$ sudo dnf -y install motion
</pre></div>
</div>
</div>
<p>For your setup we need to modify the file <code>/etc/motion/motion.conf</code>. For now the most important parameters are <code>videodevice</code>, <code>snapshot_interval</code>, and <code>target_dir</code>. We are going to use the device <code>/dev/video1</code>, use a 30 seconds interval, and set the path to <code>/tmp</code>. Edit <code>/etc/motion/motion.conf</code> or use <code>sed</code>.</p>
<div class="highlighter-coderay"><div class="CodeRay">
<div class="code"><pre>$ sudo sed -i 's|videodevice /dev/video0|videodevice /dev/video1|g' /etc/motion/motion.conf
$ sudo sed -i 's|target_dir /var/motion|target_dir /tmp|g' /etc/motion/motion.conf
$ sudo sed -i 's|snapshot_interval 0|snapshot_interval 30|g' /etc/motion/motion.conf
</pre></div>
</div>
</div>
<p>It’s suggested that you adjust at least <code>width</code> and <code>height</code> to get a bigger image from your camera. Now fire up <code>motion</code>.</p>
<div class="highlighter-coderay"><div class="CodeRay">
<div class="code"><pre>$ sudo motion
[0] [NTC] [ALL] conf_load: Processing thread 0 - config file /etc/motion/motion.conf
[0] [ALR] [ALL] conf_cmdparse: Unknown config option &quot;sdl_threadnr&quot;
[0] [NTC] [ALL] motion_startup: Motion 3.3.0 Started
[0] [NTC] [ALL] motion_startup: Logging to file (/var/log/motion.log)
</pre></div>
</div>
</div>
<p>Your <code>target_dir</code> will start filling up with images from your camera. <code>motion</code> will create a symlink called <code>lastsnap.jpg</code> which always point to the latest snapshot. We will setup the <a href="https://home-assistant.io/components/camera.local_file/">Local File camera platform</a> to use this file.</p>
<div class="highlighter-coderay"><div class="CodeRay">
<div class="code"><pre><span class="key">camera</span>:
- <span class="string"><span class="content">platform: local_file</span></span>
<span class="key">name</span>: <span class="string"><span class="content">Cranberry cam</span></span>
<span class="key">file_path</span>: <span class="string"><span class="content">/tmp/lastsnap.jpg</span></span>
</pre></div>
</div>
</div>
<p class="img">
<img src="/images/blog/2016-06-cranberry/cam.png" />
The “Cranberry cam” in action
</p>
<p>The machine with the attached USB camera will become a webcam server as well because <code>motion</code>’s built-in HTTP server is enabled by default. This means that you could connect your USB webcams to a different machine in your network, run <code>motion</code> there, adjust your firewall rules, and use Home Assistant to display the videos. Just check <a href="http://[IP of your webcam host]:8081/">http://[IP of your webcam host]:8081/</a> to see the stream. This required more powerful hardware than using snapshots, of course.</p>
<p>In a scenario like this needs a <a href="https://home-assistant.io/components/camera.mjpeg/">Generic MJPEG IP Camera </a> in your <code>configuration.yaml</code> file.</p>
<div class="highlighter-coderay"><div class="CodeRay">
<div class="code"><pre><span class="key">camera</span>:
- <span class="string"><span class="content">platform: mjpeg</span></span>
<span class="key">mjpeg_url</span>: <span class="string"><span class="content">http://[IP of your webcam host]:8081</span></span>
<span class="key">name</span>: <span class="string"><span class="content">Cranberry Live cam</span></span>
</pre></div>

<p><a href="http://lavrsen.dk/foswiki/bin/view/Motion/WebHome">motion</a> is a powerful tool and this blog post only showed two very simple use cases. Take a look at the <a href="http://www.lavrsen.dk/foswiki/bin/view/Motion/MotionGuide">documentation</a> of <code>motion</code> to unleash its potential.</p>
