We are experiencing difficulties accessing the IMX412 camera connected to our VOXL 2 (connector 8). While voxl-camera-server successfully detects the camera, we are unable to view the camera feed through the voxl-portal webserver or the RTSP stream. Additionally, camera input is not visible during inspection.

We have attached detailed information about our setup for your review.

This is a time-sensitive project, and we require a prompt resolution to avoid further delays. If the issue cannot be resolved quickly, we may need to consider returning the kit for a refund.

@Wesley-Gunawan When you're running `voxl-camera-server` manually it is killing the background process that is already running `voxl-camera-server`

What do you see with `voxl-inspect-cam -a` while `voxl-camera-server` is running as a background service?

## Reply by Wesley Gunawan · 2024-10-14 20:51:11 UTC (in reply to tom)

@tom Thank you for replying Tom. I am aware that voxl-camera-server was already running in the background, the reason why I manually run it is just to show that the camera hardware is connected properly. When I do voxl-inspect-cam -a, I don't see any output that indicates the image sensors receive any input information like it's supposed to be based on the documentation. The only thing that I saw was an empty table with hires_large_color, hires_large_encoded, .etc (basically everything in the Multi-View).

## Reply by tom (ModalAI staff) · 2024-10-14 20:55:24 UTC (in reply to Wesley Gunawan)

@Wesley-Gunawan Can you post the contents of `/etc/modalai/voxl-camera-server.conf` ?

## Reply by tom (ModalAI staff) · 2024-10-14 20:56:10 UTC (in reply to tom)

@tom As well as the output of `voxl-inspect-sku`

## Reply by Wesley Gunawan · 2024-10-17 05:31:58 UTC

Hi Tom, I only have the access to the device several days a week, please let me know the complete information you need if further information is needed. Here is the outputs requested:

voxl2:~$ cat /etc/modalai/voxl-camera-server.conf
/**
 * voxl-camera-server Configuration File
 *
 * Each camera has configurations for up to 4 HAL3 streams:
 *    - `preview` stream for raw unprocessed images from CV cameras
 *    - `small_video` 720p (ish) h264/h265 compressed for fpv video streaming
 *    - `large_video` 4k (ish) h264/h265 for onboard video recording to disk
 *    - `snapshot` ISP-processed JPG snapshots that get saved to disk
 *
 * on QRB5165 platforms (VOXL2 and VOXL2 mini) you can only have 3 of the 4 enabled
 *
 * This file is generated from default values by voxl-configure-cameras.
 * Do not expect arbitrary resolutions to work, the ISP and video compression
 * pipelines only support very specific resolutions.
 *
 * The default video compression mode is cqp or Constant Quantization Parameter

@Wesley-Gunawan Hi Wesley, I faced a similar issue recently. I was using IMX678 Hires Camera in J7U. The camera was detected when I run `voxl-camera-server -l`, even the green led light on the sensor glows but I didn't get any data run I run `voxl-inspect-cam -a`. I had an alternate IMX678 camera and without changing any config, I replaced it and it worked. I don't know what is wrong with the first sensor. I should probably do RMA, but yeah, if you have another sensor, give it a try!

## Reply by Moderator (ModalAI staff) · 2024-10-24 19:35:21 UTC (in reply to itsnav)

@Wesley-Gunawan can you please share a picture of your setup? It needs to match a camera config found here: https://docs.modalai.com/voxl2-camera-configs/

Often when a camera can't be found:
1. it's installed backwards
2. the cable isn't fully connected or the connector is damaged
3. the wrong camera config has been configured during setup

@Moderator 

Hi, the camera is connected correctly because when the configuration or installation setup isn't correct, voxl-camera-server wouldn't even detect the camera's connection, in this case it does, but no input from the camera has ever been acquired. Here is the image of the setup:
![IMG_2510.jpeg](https://forum.modalai.com/assets/uploads/files/1729831582907-img_2510-resized.jpeg) 

Is there any other information you need to help me debug this issue? It's been over a week and I need it working as soon as possible or else I have to return the whole kit. As for the camera defect possibility suggested by a user in this forum last week, I already tried swapping the camera and it still doesn't work.

## Reply by Moderator (ModalAI staff) · 2024-10-25 17:02:53 UTC (in reply to Wesley Gunawan)

@Wesley-Gunawan It looks like you are using a C08 config. https://docs.modalai.com/voxl2-camera-configs/#c8---hires-only

Have you tried ```voxl-configure-cameras 8``` ?

voxl-camera-server [documentation for troubleshooting](https://docs.modalai.com/voxl-camera-server/#troubleshooting) recommends running ```voxl-camera-server -d0```. Can you try that and paste the output?

## Reply by Wesley Gunawan · 2024-10-25 17:39:43 UTC (in reply to Moderator)

@Moderator It is camera configuration 8, the board wouldn't detect the camera otherwise (tried that before) so I'm assuming the camera configuration is correct.

@Wesley-Gunawan that looks like it's running properly. Can you open another terminal and run ```voxl-inspect-cam -a``` ?

@Moderator I already tried that in the past, even before I consulted this forum, the output has always been like this![Screenshot_20241025-132204.png](https://forum.modalai.com/assets/uploads/files/1729887798752-screenshot_20241025-132204.png)

@Wesley-Gunawan Can you please set and run inspect-cam again?

@Wesley-Gunawan did voxl-inspect-cam show anything while voxl-camera-server was running? it looks like you restarted voxl-camera-server while voxl-inspect-cam was running. 

I think the proper steps are:
1. update config (done)
2. reboot VOXL 2
3. run voxl-inspect-cam -a

This is after power cycle (poweroff -f, power source off, turn on again)
