== Technical overview ==
* Sensor: OV9281, monochrome, 1 MP, global shutter
* Interface: CSI; connector looks like the DSI connector – mind correct position when connecting
* CSI port is between the audio jack and HDMI port; on Pi Zero it is beside the power connector
* For Raspberry Pi 5: align the metal side of the FPC cable toward the LAN port; either CSI port can be used
* Bookworm configuration: edit /boot/firmware/config.txt, set camera_auto_detect=0 and add dtoverlay=ov9281
* Uses the libcamera driver (not Raspicam)
* Start preview with: sudo libcamera-hello -t 0
* Close the window via Alt+F4 or terminate in terminal with Ctrl+C
* Capture a JPEG: libcamera-jpeg -o test.jpg
* Exposure control available via --shutter and --gain

== Notes and version constraints ==
* Source contains template placeholders ({{{name2}}} etc.) – these were ignored
* Only libcamera driver supported; no Raspicam support for OV9281
* No IR filter present; IR LEDs can be added directly for night capture
* Version-specific config paths: older systems use /boot/config.txt, Bookworm uses /boot/firmware/config.txt
* Exact focus value (%focus) is module-dependent and may require a custom tuning file entry
* No price, stock, or warranty information included in the source
