I'm running voxl2 out of the box with no changes, the board is powered by an external LIPO battery and plugged into the desktop computer via USB-C. I'm trying to follow the tutorial to access the camera data but I'm unable to start voxl-camera-server. Can this server be started without an internet connection?

@KnightHawk06 , please upgrade your VOXL2 SDK, as you have very old release, you can get the latest SDK 1.4.0 and then configure your cameras.

https://docs.modalai.com/sdk-1.4-release-notes/

After installing latest SDK and configuring cameras, confirm via ADB shell that camera server is getting camera data:
```
#this test app will subscribe to all camera streams and report stream resolution, fps, etc
#please note that this test can put unnecessary stress on the system because it will stream ALL the possible camera streams, so normally you would not run this test all the time
voxl-inspect-cam -a
```

after that, if you want to view the camera stream using `voxl-portal` but you do not have internet connection, you can do that using adb port forwarding trick : https://docs.modalai.com/voxl-portal-via-adb/

Let us know if you have any other questions.
