Camera controls for Linux

It's a standalone Python CLI and GUI (GTK3, GTK4, TK) and camera Viewer (SDL) to set the camera controls in Linux. It can set the V4L2 controls and it is extendable with the non standard controls. Currently it has a Logitech extension (LED mode, LED frequency, BRIO FoV, Relative Pan/Tilt, PTZ presets), Kiyo Pro extension (HDR, HDR mode, FoV, AF mode, Save), Systemd extension (Save and restore controls with Systemd path+service).

PTZ controls

- Keyboard

Control your PTZ camera with the arrow keys/keypad keys/wasd/Home/End/PageUp/PageDown/+/-/Ctrl++/Ctrl+- of your keyboard while one of the PTZ control is in focus.

Use Alt+PresetNum to select a preset for logitech_pantilt_preset.

- 3Dconnexion SpaceMouse

Control your camera with your 6DoF SpaceMouse.

Z => zoom_absolute, X => pan_absolute, Y => tilt_absolute, RY => pan_speed, RX => tilt_speed

It requires spacenavd and libspnav. (optional, only if you have a SpaceMouse)

sudo apt install spacenavd libspnav0
sudo cp /usr/share/doc/spacenavd/examples/example-spnavrc /etc/spnavrc

or via dnf:

sudo dnf install spacenavd libspnav

tip: set led = auto in /etc/spnavrc

Partnership opportunity for vendors

Linux usage is increasing every year, currently around 3-4%.

Due to the low adoption of Linux, Camera control software with custom controls is usually only available for Windows/MacOS, so Linux users cannot take advantage of the true potential of each camera.

If you want happy Linux customers and if your camera has custom controls that are missing from this app, just send me a camera and I'll add them. Contact

Or of course, you can create a PR.
