LTS LTN8716-P8 is the none 4k version. and you have the lastest firmware. the firmware you post for newer model. from my own experience, if the OEM come with 3.4.96 or older I can flash them to 4.1. if came with 4.1.XX I can't not.
If money not the problem. VMs. But they only want to spend X amount of money for 65 4k Hikvision cameras and recorders
