Technical overview

  • The camera connects via the CSI port. On Raspberry Pi 5, align the metal side of the cable towards the LAN port; two CSI ports are available.
  • Supported sensor chips include OV5647, OV9281, IMX219, IMX290/IMX327, IMX378, IMX477, IMX519, IMX708 and IMX296.
  • For non-official cameras, set camera_auto_detect=0 in config.txt.
  • To enable a specific sensor, add a dtoverlay line, e.g., dtoverlay=ov5647.
  • Two cameras can be connected simultaneously by specifying cam0 and cam1 after the dtoverlay entries.
  • The preview can be started with rpicam-hello and stopped using Ctrl+C.
  • rpicam-jpeg is used to capture JPEG images; parameters like --shutter and --gain allow exposure control.
  • The IR LED has an operating voltage of 3.3V.

Commands and examples – verify before use:  

sudo nano /boot/config.txt
dtoverlay=ov5647
rpicam-hello
rpicam-jpeg -o test.jpg -t 2000 --width 640 --height 480
rpicam-jpeg -o test.jpg -t 2000 --shutter 20000 --gain 1.5

Notes and version constraints

  • DSI connectors (display) and CSI connectors (camera) look identical; pay close attention when connecting.
  • Older systems (Bullseye) require libcamera commands, while newer systems (Bookworm) use rpicam commands.
  • Switching between Normal and Night-vision modes requires adding disable_camera_led=1 to config.txt or making a GPIO connection.
  • For certain sensors like IMX290 on Raspberry Pi 5, an additional JSON file must be placed in the libcamera directory.
