When I go to the interface and "setup/system/upgrade" I see
System Version:3.215.0000001.0Build Date:2018-03-26
When I go to "info" tab I see
Device Type:NVR
Record Channel:16
Alarm In:4
Alarm Out:2
SN:[redacted not sure if helps]
Web Version:3.2.3.95223
Onvif Version:2.4.1
System Version:3.215.0000001.0, Build Date: 2018-03-26
The device says
NVR5216-4KS2 on the bottom
Is 1.0 on system version a hint??
Andy's list shows DHI-

My system is in the list but not sure what v1, v2 means. It is an older (2017 purchase but the 5216 line...).
Should I try the 2020 or the 2019 4.0 firmware.
If it goes wrong is there a thread in here on reverting. Assuming I just reset to defaults then load the older, then load the backup config.
Not sure if it requires
tftp server and doing trick/tweak loading on boot??
