I followed a guide on youtube to set up my raspberry pi. I'm trying to use python for facial recognition but the camera is not working.

I did

vcgencmd get_camera

in the terminal but the result was

supported=0 detected=0

Does anyone have any idea why supported shows 0?

  • maybe the camera is not supported ... or it is not connected ... or it is defective ... or etc. etc.

    supported=0 means you haven't enabled camera at all - note: you hopefully are running buster, not bullseye

    lsb_release -a - go back to buster by downloading and flash buster image

    let me make that clearer ... buster lite - no GUI and buster regular - with GUI - as far as flashing the image - what did you use this time

If you are using the new Raspberry Pi OS, the camera interface is disabled. The workaround is to open a terminal Ctrl+Alt+t and type sudo raspi-config, go to Interface Options and then Legacy Camera and reboot. These camera interfaces are deprecated and will not be supported going forwards. So use with caution and check for updates.

I used the libcamera-still command and it worked in the morning Then i installed dlib After that the same command showed the error "no cameras available" I could access camera through raspcontroller...but not through camera legacy. I could access it through camera (usb) Then i tried sudo apt-get install fswebcam fswebcam image.jpg ...and bingo ! It worked.

  1. Check first if the camera is supported

2. Try a powered USB hub to plug in the camera / maybe it isnt getting enough power

Then you can install this tool to test out the camerasudo apt-get install luvcview
