Dahua NVR - Can I receive IVS Push Notifications on DMSS app via public IP and open inbound ports with P2P Disabled?

Hello,

I have a basic question about your Dahua XVR and NVR devices.

My recorder is in a location that has a static fixed public IP address.

If I have deactivated P2P, the IVS push messages do not arrive, only SMD messages arrive when I switch them on as a test.

I have created incoming port forwarding in the router for:

TCP 39001 (as a replacement for 37777)
TCP 39002 (as a replacement for 80)
TCP 39003 (as a replacement for 443)

I have the following devices in operation under the static public IP address:

For all these devices (NVR, IPCAM directly) I have subscribed to SMD, IVS Intrusion and IVS Tripwire on 2 smartphones and SMD, IVS Intrusion and IVS Tripwire are set correctly on the NVR
When I compare it in parallel with SmartPSS Lite (latest version), the IVS rules flash red.

On any smartphone with DMSS app:
  • no Dahua account, because devices that are integrated locally cannot be transferred to the Dahua account anyway
  • 2 separate admin users have been created for the 2 smartphones with DMSS app, because I read somewhere that it would otherwise cause problems if SMD/IVS subscriptions were made on different devices with the same account.

Camera (IP) Dahua IPC-HDW3441T-ZS-S2 - always sends the push messages 100%, even if P2P is off.

Recorder (coaxial) Dahua XVR5108HS-4KL-I3 - sends the push messages SMD correctly when P2P is off (this is correct behavior is far as I know). When I turn P2P on, the status message says “Offline” and the IVS arrive correctly. However, if I switch P2P off, IVS push messages no longer arrive.

The recorder (IP) Dahua NVR5208-EI is also connected to the same static public IP address. THIS IS WHERE MOST OF THE PROBLEMS OCCUR. The NVR sends the push messages SMD correctly to the smartphone when P2P is off. If I switch on P2P, switch off SMD and switch on IVS, the status message says “Offline” and the IVS arrive correctly, BUT ONLY FOR AN UNDETERMINED TIME, after which no more push messages are received on the smartphone. The messages only reappear on the smartphone after the camera has been restarted (not after the recorder has been restarted) and stop again after an unspecified time.

I have already contacted different members of the Dahua support team and everyone told me different "steps to solve this", some of these recommendations were contradictory and had no logic. It seems to me that the manufacturer is overwhelmed by this.

Is it technically possible to receive push messages (IVS Tripwire, IVS Intrusion) on the smartphone if I have set up the smartphone via public IP e.g. 80.128.x.x and port 39001 and subscribe to the IVS rules if I have disabled P2P?

Do you have any idea what the problem could be?

Thanks for any help.
 
Yep, See this thread:

Thread 'Dahua NVR, DMSS and P2P - How are they connected?'

So this is just a thread on my own testing/research of Dahua NVRs and how they interact with Dahua P2P and the DMSS app. YMMV
It can get quite complicated....and I caution that there have been different results from past versions of the DMSS app. SO, if you're using an old version of the app you may see different results.


Part #1)
Testing Remote Push Notifications

Lets start with how a Dahua NVR (older model NVR5216-16P-4K2SE) interacts with the DMSS app (Version - 1.99.842 / 11/12/2024 - reasonably new) to send you push alerts
I have no reason to believe that newer NVRs...

  • In my testing I didnt specifically test SMD vs IVS. I can't see how there would be any difference.
  • P2P was not needed and its not in any way tied to IVS
  • Push messaging is embedded directly into the NVR firmware
  • I did not test sending to a public WAN IP as I dont run port forwarding on any of my NVRs
  • You need to open port 8888

I guess you already answered your own question in bold with your first observation:
Q: Is it technically possible to receive push messages (IVS Tripwire, IVS Intrusion) on the smartphone if I have set up the smartphone via public IP e.g. 80.128.x.x and port 39001 and subscribe to the IVS rules if I have disabled P2P?​
A: Camera (IP) Dahua IPC-HDW3441T-ZS-S2 - always sends the push messages 100%, even if P2P is off. ​
So for me that is a Yes if you can see live image and recordings through the DMMS APP as well!

It seems you encounter issues when using a NVR to receive the IVS push messages. Most likely this depends on the hardware/firmware used on the NVR and/or the order of how you setup the configuration in NVR and DMSS APP.
I would suggest to start over from scratch (factory defaults) on NVR as on DMSS APP with only 1 NVR and 1 Cam and setup the IVS in the NVR if possible . Only enable "send push messages" inside the NVR and don't ever enable P2P and see if this will generate the required push messages. If not , escalate to Dahua support and ask for an explanation.
 
I never setup IVS on the NVR, only on the camera. Mine works fine

P2P has nothing to do with push messages
