In the past month I was thinking about ways 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 am 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>

<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 http://[IP of your webcam host]:8081/ to see the stream. This required more powerful hardware than using snapshots, of course.</p>
