Hi ModalAI teams,

I have questions about camera configuration and its view.

Based on other [discussion](https://forum.modalai.com/topic/1789/extra-leds-and-buzzer-control-from-voxl-2-j3-j5), our extension board will have a USB interface FLIR Boson 640 camera.  What [camera configure](https://docs.modalai.com/configure-cameras) should we set?
Is “3  Hires + Stereo + Tracking” right?

If the camera were configured normally, I expect all the camera has its own view on VOXL Portal. But our user scenario has one more USB camera. Did it require modify the voxl-portal source code or just modify the configuration of voxl-streamer?

Is voxl-portal “camera view” source from RSTP?

Hi,

The configure cameras script only affects the MIPI cameras plugged into J6, J7, and J8 on the board. For USB cameras you should look at [voxl-uvc-server](https://gitlab.com/voxl-public/voxl-sdk/services/voxl-uvc-server) and ```voxl-configure-uvc```.

As for portal, it's fully dynamic based on which cameras are being published over our mpa services, so if you configure UVC server correctly it'll appear there alongside any other cameras that camera server is publishing (or any overlays coming from VIO/tag detector/etc). 

voxl-portal is its own standalone service doing http streaming with mjpeg (not RTSP), it has nothing to do with voxl-streamer, which does our rtsp streaming if you're viewing in VLC/QGC/etc

Hi @Alex-Gardner , @tom, 

Thanks for your information,

I have another question about [SUPPORTED SENSOR SETTINGS
](https://docs.modalai.com/voxl2-camera-configs/#141-supported-sensor-settings).   I saw IMX412/577 only support 1920X1080@30fps now, may I know what Resolution@FPS will be supported at IMX577 in the future and its schedule
