Dahua AI NVR SMD problems

[jarrow]

Hi,

I've got the new NVR5216-EI NVR with firmware DH_NVR5XXX-EI_MultiLang_V4.000.0000000.1.R.230620.
Connected are 10 older Dahua cams without AI capabilities (HDW2320R-ZS) and 1 HFW5442TP-ASE.
The cams are all added to the recorder as 'Private' (no ONVIF).

Now the problem: I can't get SMD to work with any of the cams. According to the specs it supports 8 channel SMD by recorder.
Even the 5442 with built in AI won't show its SMD recordings, while I can see in the logs of the cam itself that it generates the notifications.

What I've tried:

• Reset the MD, SMD and alarm disable periods to be on all the time
• Reset the MD region
• Re-add the cams
• Just have 1 channel SMD by recorder enabled (in case the AI bandwidth is exceeded)
• Checked AI-Mode under AI->Parameters->Local->Smart plan

Firmware is the most recent, recorder is original Dahua (no OEM).

Yet I get zero SMD recordings when looking in DMSS, by using smart search in the GUI and by using the search fuction.

Any idea on how to resolve?

Have you enabled the motion detection in the record schedule?


You also need to have motion detection enabled for smart motion detection to be enabled.
Standard motion detection may still be accessed through menu > alarms > Motion detection, then go back to menu > AI > SMD.

Thanks @Mark_M! Yea I had the yellow MD activated. When I try to activate both, the other gets deactivated. I'll try in MD&Alarm for a while.

Motion detection was on.

IVS by recorder does work on one of the old cams, but only with SMD disabled.

 

[bigredfish]

Right because I think you're limited to 1 AI function at a time. SMD=AI powered MD

Yes exactly, but IVS by recorder only allows for 4 channels and I'd like SMD on 8 channels... So using IVS instead of SMD isn't really an option.
Any tips to try? I've had all IVS rules off and tried SMD but not a single event comes through, not even the ones from the cam with built in SMD.

Regular & MD & IVS must be selected all times on all Channels in Storage->schedule. Did you copied schedule from channel 1 to all other channels?

For me Imou life mobile app works much better with dahua nvr that DMSS. In both cases (Imou, DMSS) to see events in chanel view from NVR you must use app in account mode (Create account in cloud) and after that add NVR using P2p (must be enabled in network config in NVR)

Yes did all of that.

To clarify, I have over 30 recorders running as a installer, but haven't encountered this problem before. This is also the first NVR5216-EI I've installed for a client who had a NVR5216-4KS2 before which died (after 7 years). Told him that the more expensive unit would give him AI on his existing cams, like it should (and does, but not SMD somehow).

On all these recorders, a cloud account was never needed and I always tell my clients to press 'Not now' when it prompts for an account creation.

The SMD events are not generated in the NVR, because I also can't search for them there:

I probably known what is the problem.
EI series have a new function: AcuPick, which disables previous local AI processing done on NVR.

Go to SmartPlan, then select Local tab and then select AI Mode (disable AcuPick). NVR will restart and You will have old AI functionality (SMD, IVS) done on NVR.

After You do that, go to AI -> Parameters -> SMD (or IVS), select non AI channel, select AI done by recorder and save. On all non AI channels.

Checked AI-Mode under AI->Parameters->Local->Smart plan

Yes did that too.

I just got a first SMD event by turning the sensitivity of MD all the way down to 1. I only get the event as a notification in DMSS, but can't find it using AI search or when searching for SMD events by using playback in both DMSS and the recorders GUI.

Check is SMD/IVS/events working locally in 5442 (put some SD card into, setup storage schedule locally on 5442, connect DMS directly to 5442). If everything works ok on 5422 and not on NVR, something wrong is configured on NVR.

If this is case, I would go into defaulting to factory settings on NVR. Then adding only 5442 + configuring SMD/IVS events to work with NVR. And after that (if 5442 works ok with NVR) adding/configuring rest of cams (non AI).

Like indicated in post #1, that all works. So its indeed something with the NVR. Think factory reset would be the best course of action indeed, thanks.

I personally think its a bug in the firmware, that the SMD events are incorrectly being labeled as MD events.

The notifications can be matched to motion detection events in the timeline, while the notification says 'Human motion detection'.

Good day, did anyone get a solution for this SMD issue with the Dahua 5216EI NVR (my model is the 5232EI)? I have tried all that was mentioned above but still have the issue. Thanks in advance

 

[Dre868]

RESOLVED!!!!!!

Good day all. the issue have been resolved. I sent a query out to Dahua and they advised me to reformat the hard drive, which resolved the issue.

this sound like failing HDD..

Check Storage -> Disk Check -> Check Report -> S.M.A.R.T status of each disk on NVR menu and look for high current values of read / seek disk errors...

Thanks for the response. Drive health is good. My issue started after removing the hard drive from another NVR and placing it into my new 5232EI. Seem like it needed to be reformatted with the new NVR. As mentioned, my SMD issue have been resolved and all is working well now.

I decided to update this post in case if anyone else is having the issue.

Hi,
I had the same problem after HDD format.
I changed from AI mode back to ACU Pic and after the restart changed back to AI mode again.
After this SMD/AI records and Infos are working like before.

good luck
