Getting the hang of it

Hey guys,

So I bought my mother a NVR16CH-16P-2AI with 5 Dahua cameras. I'm running it headless as I'll be managing it from her workstation in her study. There is an 8TB WD Purple installed.
I got it working to the point where I have initialized the cameras and I can see the live feeds, but I'm a little bit lost as to how best to set up event recording.
I looked up a few tutorials on YouTube, but these seem to be using models that are much older than hers, so no luck there.

At the moment, it's just set up to record mainstream 24/7, but I played around with the IVS setting on a camera, setting a 'zig zag' tripline through her front yard to record anything that comes up as either human or vehicle, but no matter what, the camera itself sounds a LOUD alarm when it detects a hit. This is despite the 'camera alarm' being unticked on that channel.

The only way I could stop the camera from playing an alarm was to remove all IVS rules completely.

I used both Edge and Firefox, and these issues persist.

Is this a browser issue? Or is there something that I'm not doing correctly?

Is there an online tutorial that is relevant to this model of NVR that I can follow to explore different recording options and how to set them up?

Thanks for any help.
 
Best practice is and continues to be accessing the camera GUI via a web browser and not within the NVR. That is the same whether it is old or brand new.

It appears you are trying to set camera settings in the NVR GUI and not the camera GUI. It also best to use Internet Explorer, Pale Moon, or Edge with IE tab.

To get into the camera GUI from the NVR, you need to first access the NVR GUI by going to a computer and opening up a browser (preferably Internet Explorer (yeah we know) but Pale Moon will work as well) and type in the IP address of the NVR and login that way. Next go into the camera settings page on the NVR and look for the Microsoft e Web Browser and select it and it will go to the camera GUI (photo credit bigredfish from his PSA thread). Your screen may look a little different to get into the camera gui and see if doing it this way gets you access to some other features the NVR is blocking - do not worry about the Port number and circle as that was from another issue someone posted.

The user/pw for the cameras should be the same as the NVR unless YOU changed the camera user/pw.


How to enable native Internet Explorer in Windows 10 and 11:
  • Open Notepad:
    • Copy then paste the single line of code below into Notepad:
    • CreateObject("InternetExplorer.Application").Visible=true
    • Save as OpenIE.vbs
  • Make sure the the file name ends in .vbs not .txt, If it ends in .txt you must rename to .vbs
  • Create a shortcut to the above file and double-click it anytime you want native Internet Explorer.

This should be fairly close:

It’s not plug and play. You have many hours /days of learning ahead of you

On the NVR:
For Recording go to Storage. Make sure each day and channel is set to record wfat you want recorded. Full time:/General as well as IVS/Intelligent.

Also check the Record Mode tab and be sure Main Stream and snapshot are Auto

Thanks! I'll give it a go.

I've already tried that trick with enabling IE in Win 11, but the performance is SLOW. Just navigating different pages within the NVR UI is incredibly laggy, and even when viewing video previous in the IVS screen for example, scrolling down requires that the browser freezes while the video feed terminates before it allows me to see the rest of the page. Additionally UI elements are scaled in different proportions. Some text is incredibly tiny, other elements are ridiculously huge. Is there a plugin or something which fixes these issues?
 
Another question: Should the PoE indicators be red? I'm getting live feeds successfully from all cameras, and they're all plugged into the inbuilt PoE ports.

Does this look right?
This is for all cameras and 7 days.

Snapshot should have both green and blue as well

FWIW i run substream 1 on AUTO as well. It helps when you need to playback clips remotely

I use Edge in IE mode and it works fine.

If you are local to the NVR and experiencing lags like that, its not the NVR

Done.

I have one camera that only has mainstream and substream 3 enabled (SS 3 is the only way to get 720p recording out of it). Will this still pick it up?
 
I cant be sure about SS3, never tried
 
? Dunno. Use SS2?

Please Refer to our guide video, actually we have a QR code on the NVR box to scan for the guide video.

Thanks, I've followed this entire video, and turned acupick off and enabling AI mode, but even though I have enabled motion detection and SMD on all channels for humans, I still don't see any 'blue' intelligence recordings, it's all just green for general recording.
What am I doing wrong?
 
Why would you use MD and SMD?

Most here use IVS for human detection. You will get a lot of false triggers with SMD.

The video Andy linked said specifically that SMD is a 'filter' for MD.

Whenever I enable IVS, it triggers the alarm sound on my cameras for some reason, even though I have it unchecked as per my screenshot in the OP.
 
Some people don't like SMD. I use it on my DVRs that support extra SMD channels past my AI channels. Main issue is when you bring up your playback or search depending on model. IT will have a load of Yellow motion marks and might be all day in area like mine with loads of Rain, Snow, bugs and all other things that just happens around here.. However as you said a filter, So you can pick SMD in search and will pick out only real motion by Human and Vehicles. To top that off. Rather then having full time motion enabled for alerts on your phone app, Pick the SMD and it will give you the option for Vehicle or Human. When for IVS it is Tripwire with no option for what the tripwire was.. So with respect to ability to have quality notices SMD will let me know when a human is coming up my Driveway on my DVR where my NVR with tripwire on the driveway where I have 2 tripwires set one for Vehicles and other for humans in my driveway it will just tell me that there was a Tripwire event not even what one was triggered..
