Ah ok, thanks for the reply.
It’s stopped recording and freezes when trying to use the NVR. In the Hik connect app it jas the playback there but when you press play nothing happens. :(
It says there is no more capacity on my hard drive, I have had it installed for 13 months and it’s been overwriting then. What is this issue and how is it solved as I’m a 2 hour drive away from my friends restaurant where I installed it. Kind regards for any help :)
