Raspberry PI Zero 2W camera

  1. Get the imager https://www.raspberrypi.com/software/ and write to sdcard, configure the dialogues

2. Plug in the sdcard, start the raspberry and log in via putty (find IP on router)
-> an USB port might not be powerful enough for heavy operations, so preerably a power outlet

3. Update and install workloads


sudo apt update
sudo apt full-upgrade -y

sudo apt install -y \
  rpicam-apps \
  python3-picamera2 \
  python3-numpy \
  python3-av \
  ffmpeg \
  samba

sudo reboot

Test the camera

rpicam-hello --list-cameras

Create directories

mkdir -p ~/camera ~/videos ~/timelapse

Upload scripts (via powershell)

scp C:\ZeroCameraBackup\record-motion.py xxx@Zero.local:/home/xxx/camera/
scp C:\ZeroCameraBackup\aim-camera.sh xxx@Zero.local:/home/xxx/camera/
scp C:\ZeroCameraBackup\timelapse-camera.sh xxx@Zero.local:/home/xxx/camera/

In putty:

chmod +x ~/camera/record-motion.py
chmod +x ~/camera/aim-camera.sh
chmod +x ~/camera/timelapse-camera.sh
