Purchased a Hikvision NVR and 13 Hikvision cameras from AiiExpress a few weeks ago. I still can't get the system configured and any suggestions would be very welcome. I tried to get help from the US Hikvision site, but they won't support devices not purchased from their approved US suppliers. The NVR is supposed to be "plug&play", but that's not what I'm experiencing. First thing I noticed is that the user setup of IP address, password, time and date will not persist when the NVR is turned off and back on. When I tried to update the firmware it starts to make the update, but then stops with the message "unable to update, not enough room in flash memory". I can see all the IP cameras from the LAN side when I individually input their IP address. Port forwarding rules are correctly configured. Again, any suggestions are most welcome.
