Is the npm warning expected ?

First I thought it was one of the modules that load huge picture or video from google. But it happens as well with a very simple config.

I changed the power supply to 2.5A. But it still happens.

Any help ? What should I look for in the logs ?

Thanks

@alberttwong My camera feed sometimes suddenly stop streaming. How do I debug this ?

nagaculun

@cyberphox I ended up using the global zoom.
