Compatibility Notice
Due to breaking changes in the Raspberry Pi OS camera stack, this software will not work with the recent Bullseye version of Raspberry Pi OS. A new integration library is currently under development by the Raspberry Pi Foundation with a planned release in early 2022. Our camera software will be updated to take advantage of this integration library when it becomes publicly available.
In the meantime, if you wish to use this software you will need to install the Buster version of Raspberry Pi OS.
Camera Zero
Combining Camera Zero with an Arducam 12MP camera, a Raspberry Pi Zero WH, a PiMoRoNi trackball breakout, and an Adafruit 16-LED NeoPixel ring will result in a neat little screenless camera that can be controlled with your thumb.
Getting Started
- Use raspi-config to:
- Set the Memory Split value to a value of at least 192MB
- Enable the CSI camera interface
- Enable the I2C interface
- Set up your WiFi connection
- Connect the camera to your Raspberry Pi
Installation
Installation of the program, any software prerequisites, as well as DNG support can be completed with the following two-line install script.
wget -q https://raw.githubusercontent.com/eat-sleep-code/camera.zero/master/install-camera.sh -O ~/install-camera.sh
sudo chmod +x ~/install-camera.sh && ~/install-camera.sh

Disabling Autostart
To disable autostart of the program, execute the following command:
sudo mv /etc/service/camera.zero/run /etc/service/camera.zero/run.disabled
Infrared Cameras
If you are using an infrared (IR) camera, you will need to modify the Auto White Balance (AWB) mode at boot time.
This can be achieved by executing sudo nano /boot/config.txt and adding the following lines.
# Camera Settings
awb_auto_is_greyworld=1
Also note, that while IR cameras utilize "invisible" (outside the spectrum of the human eye) light, they can not magically see in the dark. You will need to illuminate night scenes with one or more IR emitting LEDs to take advantage of an Infrared Camera.
