  23       <div class="title">Managing and using ONVIF IP cameras with Linux</div>
  24       <div class="date">19th October 2022</div>
  25       <div class="body"><p>Recently I have been looking at how to control and collect data
  26 from a handful IP cameras using Linux.  I both wanted to change their
  27 settings and to make their imagery available via a free software
  28 service under my control.  Here is a summary of the tools I found.</p>
  29
  30 <p>First I had to identify the cameras and their protocols.  As far as
  31 I could tell, they were using some SOAP looking protocol and their
  32 internal web server seem to only work with Microsoft Internet Explorer
  33 with some proprietary binary plugin, which in these days of course is
  34 a security disaster and also made it impossible for me to use the
  35 camera web interface.  Luckily I discovered that the SOAP looking
  36 protocol is actually following <a href="https://www.onvif.org/">the
  37 ONVIF specification</a>, which seem to be supported by a lot of IP
  38 cameras these days.</p>
  39
  40 <p>Once the protocol was identified, I was able to find what appear to
  41 be the most popular way to configure ONVIF cameras, the free software
  42 Windows tool named
  43 <a href="https://sourceforge.net/projects/onvifdm/">ONVIF Device
  44 Manager</a>.  Lacking any other options at the time, I tried
  45 unsuccessfully to get it running using Wine, but was missing a dotnet
  46 40 library and I found no way around it to run it on Linux.</p>
  47
  48 <p>The next tool I found to configure the cameras were a non-free Linux Qt
  49 client <a href="https://www.lingodigit.com/onvif_nvcdemo.html">ONVIF
  50 Device Tool</a>.  I did not like its terms of use, so did not spend
  51 much time on it.</p>
  52
  53 <p>To collect the video and make it available in a web interface, I
  54 found the Zoneminder tool in Debian.  A recent version was able to
  55 automatically detect and configure ONVIF devices, so I could use it to
  56 set up motion detection in and collection of the camera output.  I had
  57 initial problems getting the ONVIF autodetection to work, as both
  58 Firefox and Chromium <a href="https://bugs.debian.org/1001188">refused
  59 the inter-tab communication</a> being used by the Zoneminder web
  60 pages, but managed to get konqueror to work.  Apparently the "Enhanced
  61 Tracking Protection" in Firefox cause the problem.  I ended up
  62 upgrading to the Bookworm edition of Zoneminder in the process to try
  63 to fix the issue, and believe the problem might be solved now.</p>
  64
  65 <p>In the process I came across the nice Linux GUI tool
  66 <a href="https://gitlab.com/caspermeijn/onvifviewer/">ONVIF Viewer</a>
  67 allowing me to preview the camera output and validate the login
  68 passwords required.  Sadly its author has grown tired of maintaining
  69 the software, so it might not see any future updates.  Which is sad,
  70 as the viewer is sightly unstable and the picture tend to lock up.
  71 Note, this lockup might be due to limitations in the cameras and not
  72 the viewer implementation.  I suspect the camera is only able to
  73 provide pictures to one client at the time, and the Zoneminder feed
  74 might interfere with the GUI viewer.  I have
  75 <a href="https://bugs.debian.org/1000820">asked for the tool to be
  76 included in Debian</a>.</p>
  77
  78 <p>Finally, I found what appear to be very nice Linux free software
  79 replacement for the Windows tool, named
  80 <a href="https://github.com/sr99622/libonvif/">libonvif</a>.  It
  81 provide a C library to talk to ONVIF devices as well as a command line
  82 and GUI tool using the library.  Using the GUI tool I was able to change
  83 the admin passwords and update other settings of the cameras.  I have
  84 <a href="https://bugs.debian.org/1021980">asked for the package to be
  85 included in Debian</a>.</p>
  86
  87 <p>As usual, if you use Bitcoin and want to show your support of my
  88 activities, please send Bitcoin donations to my address

  90
  91 <p><strong>Update 2022-10-20</strong>: Since my initial publication of
  92 this text, I got several suggestions for more free software Linux
  93 tools.  There is <a href="https://github.com/quatanium/python-onvif">a
  94 ONVIF python library</a> (already
  95 <a href="https://bugs.debian.org/824240">requested into Debian</a>) and
  96 <a href="https://github.com/FalkTannhaeuser/python-onvif-zeep">a python 3
  97 fork</a> using a different SOAP dependency.  There is also
  98 <a href="https://www.home-assistant.io/integrations/onvif/">support for
  99 ONVIF in Home Assistant</a>, and there is an alternative to Zoneminder
 100 called <a href="https://www.shinobi.video/">Shinobi</a>.  The latter
 101 two are not included in Debian either.  I have not tested any of these
 102 so far.</p>
