  • Replacement for trcking camera
    Techsawi TechsawiT Techsawi Techsawi

    Hi, my tracking camera and VIO were working perfectly until yesterday , as I had a crash landing the tracking camera got damaged (the connector part of the camera cable came out ), So I'm looking for alternate methods to replace the tracking camera,
    Is it possible to connect the hires camera in J4 as a replacement for the tracking camera?
    Or Can I connect the hires camera to any other port and is it possible to Give that feed to the VIO server by modifying the config files?
    Please suggest to me the possible ways to replace the tracking camera ...

    Hi @marian I'm trying the same solution as my tracking camera is not working, are you able to get it working this way?
