Hi all. As titled, I have a camera (Imperx Cheetah) connected via a 10gigE vision interface to my workstation. Using the imperx player I can record image sequences. I was hoping to use matlab to record videos while also triggering other relays (it’s in the seconds range so doesn’t need extremely high accuracy).
I successfully connected it via the gigecam object and can view images using snapshot. However when I try to connect to it using the videoinput object with the “gige” adapter, it can’t be found. To that end, gigecamlist returns the camera, but imaqhwinfo does not. I have two other USB3 cameras that are successfully returned when running imaqhwinfo.
When I run imaqsupport, the gentl producers that support it are detected and checked ok (Both from matrix vision and Imperx). The Imperx camera also doesn’t show up on Image acquisition explorer, but my USB3 cameras do.
I have tried using python’s harvesters package using the matrix vision CTI as a gentl producer and it worked, but I ran into some issues with the buffering and writing on that end, in that some images would be incompletely written
Would anyone happen to have any idea of any troubleshooting steps I can take to connect it to the videoinput object? I was hoping to log it straight to disk to maximize the speed I can capture at. From the documentation, it appears I have to take a snapshot and write each frame using a gigecam object.

Hey Jens,
Here are a few troubleshooting steps you can take to further investigate and potentially resolve the issue:
  1. Update MATLAB and Image Acquisition Toolbox: Ensure that you are using the latest version of MATLAB and the Image Acquisition Toolbox. Newer versions often include bug fixes and updates that could address compatibility issues.
  2. Check camera drivers: Verify that you have the latest drivers installed for the Imperx Cheetah camera. Visit the manufacturer's website to download and install any available updates for the camera's drivers.
  3. Verify GigE Vision compatibility: Confirm that the Imperx Cheetah camera is compatible with MATLAB's Image Acquisition Toolbox and supports the GigE Vision interface. Refer to the camera's documentation or contact the manufacturer for detailed information about compatibility with third-party software.
  4. Try alternative interfaces: If the GigE Vision interface is causing compatibility issues, check if the Imperx Cheetah camera supports other interfaces such as USB or Camera Link. If supported, you can explore using these interfaces to connect the camera to MATLAB through Image Acquisition Toolbox.
