Hi
@jjmsau
We tested the problem you are reporting using a Mac in our office and we were able to update a camera connected to the PoE ports of a Hikvision NVR using Chrome, we did see multiple glitches (the file folder wouldn't open when we clicked it, the update would fail, etc...) but on the 2nd-3rd attempt of each of these things we did actually get the firmware to install, the camera rebooted and when we logged back in the camera firmware had updated. (we were only updating from version 80 to 82 and so users upgrading from older firmware may still have problems)
We understand that this is nowhere near a good enough solution and just this morning we have pushed Hikvision again to give us an update on when we can expect a 'no plugin' firmware update.
