In @bigredfish example it was a bug in a beta release of the iDMSS app that they fixed in an update as evidenced by that thread is from 2019 and nobody is posting about a similar issue. Apparently Synology choses not to provide a fix.
But since you want to jump on the Dahua is banned wagon and claim Synology isn't updating Dahua cameras since they are banned, you don't think Synology doesn't sell all around the world?
Oh wait their website shows they sell to many countries without a ban. I stand by my statement that it is a Synology issue. I have your exact camera and it works flawlessly in BI and limited to 3 connections.
I got new tires for my car and now the car won't start...I am sending the tires back
