Hi @thomas.cullen,
Have you enabled the various gpu_mem variables per the balenaCam README? Also, in the HostOS, are you seeing your /dev/video1 (or similar)? I noticed, too, that the balenaCam repo has line 31 (#RUN printf "bcm2835-v4l2\n" >> /etc/modules) commented out. If that’s true in your version, the module likely isn’t getting loaded. Can you confirm that line is uncommented in your Dockerfile.template?
