No they’ve sold to some of my friends without issue but I’ve always told friends to not expect product guidance and configuration support from such sellers as that’s why Hikvision and some other brands won’t officially sell to end users.
Just to let you know, today went up to collect my DS-7616NXI-K2/16P from that company you had suggested, they are reasonably local to me. Very nice person to deal with. Overall the changeover went fine and the NVR is now up and running.
Thanks for your advice.
