How to setup a Raspicam?

What do I have to do?

You are in luck, if you are using a Raspicam.
Simply do nothing. Crowsnest is designed with Raspicams in mind, so the Installer does all needed steps for you, including some "Workarounds" to prevent changing 'Raspicams' away from /dev/video0
That means, simply set in crowsnest.conf
device: /dev/video0

But my Raspicam does'nt show up!

Run vcgencmd get_camera . This should show something similar to
supported=1 detected=1, libcamera interfaces=0
If this shows
supported=1 detected=0
check your wiring, in most cases the ribbon cable is damaged or the cam itself.
Raspicam devices that relie on libcamera interfaces are not supported at this point!
May change in the future.
