Hi @Kingzeon,
At this stage we have no official recommendations, but I’ve compiled a list of camera alternatives / improvement options that have been discussed on the forum in this comment, which may be of interest. Note that “an option has been discussed” does not necessarily mean it has been confirmed to work, or work well, and integration may not be trivial.
Also be aware that if you’re wanting to have a live 4K stream you may run into bandwidth issues. Depending on your requirements, it may be possible to have a lower resolution ‘preview’ stream to the topside, while recording the full resolution footage on the camera / in the vehicle and retrieving the footage afterwards. You may alternatively want (or need) to use a fibre optic tether, if the existing tether+Fathom-X combination has insufficient bandwidth, and it may be relevant to consider an IP camera via an Ethernet Switch as an alternative to a USB camera, depending on what’s available that meets your needs.
We are currently looking into some 4K camera options, and the relevant software considerations around supporting that, but as I understand it that’s an active investigation without an obvious best option.
