To command the camera in the terminal I suggest to use the fswebcam package. To install:
`sudo apt install fswebcam`
To take an image with a certain resolution and hide the standard banner:
`fswebcam -r 1280x720 --no-banner /images/image1.jpg`
To find the supported webcam resolutions:
`v4l2-ctl --list-formats-ext`
You could also use ffmpeg to take images and video. To install:
`sudo apt install ffmpeg`
To take an image:
`ffmpeg -f v4l2 -video_size 1280x720 -i /dev/video0 -frames 1 out.jpg`
A more advanced alternative is mjpeg-streamer, which enables you to stream the camera in a browser. You can find a detailed tutorial how to set that up here.
