@Eric-Katzfey Thanks for the explanation, I was not starting the voxl-camera-server before.
When I started the voxl-camera-server, I had my camera configuration include the tracking camera which stopped the voxl-camera-server from starting correctly.
Once I changed my camera configuration with voxl-configure-cameras to "hires only" I was able to start the camera server and then start the voxl-streamer as well.
