USB camera

This should work on any linux distro with any sane camera that you have.

How to get info which cameras are available?

Run v4l2-ctl --list-devices.

This should show list of devices to use, where /dev/video0 is a device name.

Notice that not every device is an actual camera.

How to get what modes are available for the camera?

The quick all-in one output for camera /dev/video0 is

v4l2-ctl -d /dev/video0 --all

For more details about formats it is better to use v4l2-ctl --list-formats-ext -d /dev/video0

Prepare config

copy usb.dist as .env
in copied file .env replace token-change-me with the value of the token you copied
in copied file .env replace fingerprint-change-me with some random value, which is alphanumeric and has at least 16 chars (and max of 40 chars), for example set it to fingerprint-myprinter2-camera-2
in copied file .env replace /dev/video0 with desired device in CAMERA_DEVICE
save edited file .env

Next, test config.
