Hello all, We’re working on a ROV at the moment. We are planning to use a USB Camera Module. However, we don’t want to use the one in Bluerobotics. Do you have any other camera you can reccomend us? Also, can we use ANY camera module without facing issues (with Ardusub)? Thank you. ---

Hi, Any camera that provides video in H264 via USB is compatible with the companion software layer. ---

Hi, I am trying to use the Kurokesu C1 USB camera and the video stream is working but I only get 1 fps in QGroundControl video view. Here is the datasheet for the camera: [https://www.kurokesu.com/uploads/datasheets/Kurokesu\_C1.pdf](https://www.kurokesu.com/uploads/datasheets/Kurokesu_C1.pdf) Can I change some settings to get this to work with 30 fps? Cheers, Jan R ---

Hi, Take a look in [http://192.168.2.2:2770/camera](http://192.168.2.2:2770/camera), you’ll be able to configure the camera to match the frame rate that you are looking for. ---

Hi Patrick, I am looking at the settings for the camera and it looks okay and correct, but still it is only showing 1 fps. Anything else I can try? ---

Navigate to [http://192.168.2.2::8088](http://192.168.2.2:8088:), open a terminal, and enter this command: `ls /dev/video* | xargs -L1 v4l2-ctl --list-formats-ext --all --device` Let us know the output. It sounds like our software cannot support your camera at 30fps. ---

Hi Jan, Are you sure this is the full output ? Because there is no “H264” pixel format on it. ---

To check if it’s possible to use the camera without configuration or any modification, check the following steps: 1. Go to [http://192.168.2.2:8088](http://192.168.2.2:8088) to access the companion terminal. 2. Check the connected devices with: `v4l2-ctl --list-devices` 3. Take a look in the camera capabilities with: `v4l2-ctl --list-formats-ext --device=/dev/videoX` Let us know the output for each device. ---

I use a small program for testing my USB cameras, “H264 Preview v1.16” and if I switch on the H264 encoding in that program I get the same effect of showing video in 1 fps. The moment I turn it off it goes to show 30 Fps. Can this information be helpful? Jan R ---
