- <div class="body"><p>Recently I have been looking at how to control and collect data
-from a handful IP cameras using Linux. I both wanted to change their
-settings and to make their imagery available via a free software
-service under my control. Here is a summary of the tools I found.</p>
-
-<p>First I had to identify the cameras and their protocols. As far as
-I could tell, they were using some SOAP looking protocol and their
-internal web server seem to only work with Microsoft Internet Explorer
-with some proprietary binary plugin, which in these days of course is
-a security disaster and also made it impossible for me to use the
-camera web interface. Luckily I discovered that the SOAP looking
-protocol is actually following <a href="https://www.onvif.org/">the
-ONVIF specification</a>, which seem to be supported by a lot of IP
-cameras these days.</p>
-
-<p>Once the protocol was identified, I was able to find what appear to
-be the most popular way to configure ONVIF cameras, the free software
