Hi,

I'm using VOXL2 with 4 cameras connected to it. I'm trying to capture data or get logged data from one of the cameras- https://beta-docs.modalai.com/M0014/ .

However:

* https://beta-docs.modalai.com/voxl-tracking-sensor-user-guide/ says "coming soon".
* I don't see any of the cameras output in the voxl-portal.
* Running "voxl-inspect-cam -a" doesn't show any camera output.

In addition:
 * ls /dev/video* : 
```
/dev/video0  /dev/video1  /dev/video32  /dev/video33
```

* voxl-camera-server service is not running. From inspecting the service + running it in debug mode it seems that it's getting segmentation faults:

```
voxl2:~$ systemctl status voxl-camera-server
Jan 16 19:22:30 m0054 systemd[1]: Started voxl-camera-server. Jan 16 19:22:59 m0054 bash[1415]: Segmentation fault: 
Jan 16 19:22:59 m0054 bash[1415]: Fault thread: voxl-camera-ser(tid: 1415) 
Jan 16 19:22:59 m0054 bash[1415]: Fault address: 0x564fa8d321 
Jan 16 19:22:59 m0054 bash[1415]: Address not mapped.
```

Do you know what's causing the problem - is it configuration?

In addition, once it's working, what's the best way to capture data from specific cameras? 

Thanks

You should be using docs.modalai.com , the beta-docs are only published for specific, pre-release components.

You cannot plug image sensors in where ever you like. You need to follow a supported configuration here: https://docs.modalai.com/voxl2-camera-configs/
