I have seveal different Dahua cameras in my home and I just bought the SD2A500HB-GN-A-PV-S2 model to set it up. I'm accessing substreams on all my cameras but when setting up this new one I noticed that I keep getting this error in the browser:
Error
{"result":false,"error":{"code":285278249,"message":"Authority:check failure."},"id":53,"session":2444454334}
An error like this usually appears if the user does not have the correct permissions. While "Live" and "Playback" were enough to open a MJPEG substream on Dahua IPC-HFW1435S-W-S2, I found out that a user on a later model Dahua IPC-HFW2441T-ZS in addition also requires the "AV parameter" to be able to access substream,
I made sure to add this permission for the account when setting up SD2A500HB-GN-A-PV-S2 as well, but it didn't help. I then gave the user ALL permissions, but still kept getting that error. I then deleted the user and recreated it again and made it admin (in admin group), but still got the same error. The only user that is able to open the MJPEG substream is the built-in "admin" user, even though it has exactly the same permissions as the manually added user.
The URLs I use for this (first one works, second one doesn't; they are both admins):
Did anyone encounter something like this before? It seems to be a firmware bug or something on this particular camera. There doesn't seem to be any updates for it. Is there anything that can be done, or should I return it?
