           | After briefly skimming the sources it doesn't seems to be
           | present any code to activate/deactivate an external shutter
           | or servo to rotate the camera away from sunlight. There is
           | code to turn the camera on and off but it doesn't seem to do
           | anything else beyond that.

           | the heat could still damage it, despite it not recording.

       | Unclear what the relationship is with the Global Meteor Network
       | (https://globalmeteornetwork.org/) that has people build meteor
       | cameras, often based on RPis, and then contribute the data so
       | that meteor orbits can be determined.
       | 
       | This site: https://tammojan.github.io/meteormap/ shows the
       | meteors detected over the last 24 hours. You can see that the UK
       | is pretty well covered with cameras as are some parts of Europe.
       | The US is rather sparser -- with only Arizona having good
       | coverage.
       | 
       | Building a camera is fairly easy and is under $200 -- most of the
       | parts can be ordered on Aliexpress.

         | this map?
