The setup uses libcamera-hello for camera output, Azul Zulu JDK 11 (the only viable Java runtime for ARMv6), and an embedded Jetty server to expose HTTP endpoints for adjusting zoom and resolution. The API kills and restarts the camera process to apply new settings. Includes systemd service configuration for auto-start on boot, plus performance notes showing the Pi Zero 1 W handles both the camera and Java app within its 512MB RAM. ## Full article daily.dev links to this article rather than hosting it.
