Hi @thomas.cullen,

Have you enabled the various `gpu_mem` variables per the balenaCam [README](https://github.com/balenalabs/balena-cam)? 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?

John
