I've got little experience in Linux, and Zoneminder, so I hope someone with my level of understanding will find this useful.

You can use uvcdynctrl -cv to view the available list of commands that you can control the camera with.

For example, for my Orbit AF I get a list of settings I can change:

Code: Select all

sudo uvcdynctrl -cv

To execute these and set them, you use the uvcdynctrl command.
For example:

Code: Select all

sudo uvcdynctrl -s 'Tilt (relative)' -- 1280

which successfully moves the camera.
When going into negative settings, such as -1280, please use -- -1280 so that the negative isn't seen as a command.

I still haven't got a clue how to incorporate this into a script that will allow Zoneminder to control the device, so I would like some help on that. But as far as I can see, no one has posted a "For dummies" guide on how to operate the logitech cameras. Maybe most don't, but it took me a while.

If someone could respond with how to though, I would love to use it, and allow others to see how.
Thanks!
