I ran this command vcgencmd get_camera

supported=1 detected=0

I have used the same hardware, but vanilla Rpi OS and logged into the desktop and ran

libcamera-hello -t 0 --qt-preview --shutter 3000

I got an image on screen.

Question = why does Motioneyeos not detect the camera??

[starbasessd]

Camera V3 is not supported directly in motionEyeOS ( even dev20201026 ) because it was released after the last image was published, and the new devs have not moved forward with a new image. Some people with 'advanced skills' in RaspberryPiOS have had some success in replacing the driver files and kernel and getting it to work. Your best bet if you want to use it with motionEye would be to install RPiOS Buster and then following the instructions here

[cohen-sydney]

thanks. appreciate the quick reply.

[starbasessd]

Be sure to NOT use the latest RPiOS (Bookworm) as it does NOT support Python2 or the needed APIs that motionEye uses...

[cohen-sydney]

Would Bullseye also work?? as that is simple to install from he RPI imager

[starbasessd]

Not if you want to use a Camera V3. USB, Yes. Buster has all the APIs and Python2.7 available.

Hey @cohen-sydney ,

Did you have any luck with this one? I'm in a similar boat, I got a Raspberry Pi Zero 2 with the v3 Wide Camera plugged in with the adaptor cable.

When I get MotionEyeOS running on the board, the camera always says "Unable to open video device. Were you able to get your set up running?

EDIT: Have since loaded motioneye as a service running Raspbian Buster - I'm unable to create a camera as a MMAL camera. raspistill fails to create the camera object so starting there.

I'm in the exact same boat as you @bibiqt40. Any luck so far?
