Sorted. ;)
After emailing every Hikvision support address I could find online (because UK/EU wouldn't even reply :mad:), thankfully Hikvision China took the challenge. They found that the original/bound Hik-Connect account lacked regional info, once they changed this to UK I was able to unbind...
Tried that, if I select Russian it displays a different error, something about not being bound in this region...
I'm trying lots of different F/W's now, just in case it's a bug with one of them?
Has anybody been able to successfully unbind any NVR that has given these errors?
I've tried Hik Connect via Android mobile & iVMS via local PC, both fail with either the "local area" or "same region" excuses!
I'm starting to think that this is either a S/W bug or part of the Hikvision hack...
