Hello @neilinpaemail welcome to the balena community.

could you please share more details such as:

  • what repo did you deploy on your fleet?
  • what OS are you using (Raspberry Pi 3 or Pi 3 (64 bits))?
  • what camera do you use?

Thanks :slight_smile:

Hello Mpous,

Thank you for reaching out. I used the one-click deploy from the following link below for Balena-Cam
I tried on 3 different devices. Raspberry Pi 3, Raspberry Pi 2 0 W, and another Raspberry Pi 3. I tried using Camera modules, and a USB web Cam.
I tried dev mode and prod (32bit modes) (by deleting and starting fresh 3 times basically. The attachment has the errors I always get.
