How-to guide: Pixhawk auto camera trigger (without CHDK)
f you are not using a canon camera, you then do not have access to the CHDK canon firmware which provides advanced automation scripts to automate your camera trigger on your UAV.
There exist on the market other great alternatives for all camera brands (some of them are functionally richer and simpler to use than CHDK). As an example in this guide, I will use the "Stratosnapper V2". This is a little smart thing that allows you to trigger any camera brand (Sony, Canon, Nikon, etc) by many ways : infrared, cable, LANC, etc...
