I did not hear you mention if the DUO2 uses 1 or 2 synology surveillance station licenses? The original DUO required two so it is a big plus if the DUO2 only uses 1.";}

Yes, there is a problem with Surveillance Station. It is seen as two cameras. So you will need to add left and right. Not great.
But if you link it via FTP, you will get nice full-width recordings, but no controls that you get in Surveillance Station. You can use Reolink apps for controls though (running two things simultaneously).
