I would like to use a camera for still frame acquisition for external processing via <ipaddr>:81/static_simple.html Since the usage will be infrequent, I would like to disable the camera when it is not in use.

So, my questions. On the SBC's webcam control page, does disabling the camera actually cut power to the camera, or only disable the web access? If it does actually "power down" the camera, what command would I execute from the shell to do the same thing?

Thanks.

The camera stream is provided by the mjpg-streamer deamon, which is stopped when you disable the webcam.

There are lots of tool in the Debian package repo which you can use to grab frames from a webcam.
