Dahua NVRs channel zero

[Testing123TT]

Hey guys,

On the old web UIs there was option to enable channel zero, which as you know reduces the overall bandwidth required to view all the cameras at once.

On the new UI (NVR 4.0) doesn't even mention the existence of channel 0.

Does anyone know how to enable it? Is it even possible to do so?

Regards
D

That's not it.

On my NVR these buttons are on the left, the one you point to says "View 1", the one next to it "View 4".

I'm talking about Channel "Zero" - i.e. streaming all cameras as a single stream. Perhaps you're not familiar with what I'm talking about?

Hi Man,

If you are not using IE, you might not see the buttons.

On my NVR 5216 V4 UI, no Zero Channel is available but on my XVR V4 UI, it's available via the display settings. Perhaps they removed it on the V4 UI on the NVR's.

Thats correct Paul

So, on some NVRs there's no channel 0 ?

Are you using Internet Explorer? I dont believe you will see the option on Chrome etc.

Yes, no "Channel 0" .... there's again "View 1/4/whatever" but no Channel zero..
Most likely they've removed this on some NVRs ....

It did show up on one of them at least, but for some reason when I try to start the cameras, I get "Please log in first.", even tho I'm logged into the web interface .....
Any ideas?

I've come across this quite a few times on firmware versions from 2020. Update firmware should fix it for you.

Update firmware .... if there is one
Dahua seem too lazy on the matter.
