I do use DMSS and SmartPSS Lite to connect to these cameras over the web, but I suppose I'm not expecting to see traffic logged when I'm not using the service. Do the Empire/Dahua NVRs upload my camera footage to an external server or is this just traffic moving from the cameras to the NVR? It's odd to me that the trends here fall into the 'smart' recording being the motion these cameras are detecting as events, IE, vehicles and people during daylight hours. Example being the two spikes where my cursor is would be my daughters birthday party in backyard, followed by me cleaning up for an hour after everyone left. Is there something I should be disabling? I do have wireguard setup to this network so in theory I could just connect to my router remotely and then stream video to these apps over the 'local' tunneled network rather than through the application web service.

Essentially, why is there traffic here if neither my wife or I are streaming this?

Did you use the serial number or QR code to add them to DMSS/SmartPSS?

If so P2P is running. the NVR P2p pings Dahua P2P servers continuously to say hello and insure they know how to connect to DMSS/SmartPSS

No they dont stream your video across the servers

I think what you see there is you streaming the video to your DMSS/SmartPSS remotely from the NVR

P2P is running, I believe DMSS was added by SN and SmartPSS is local IP.

Neither application is generally open or looked at - so neither DMSS or SmartPSS should be pulling data to a phone or PC more than once or twice a month if we have something to review or save.

The screenshot is a snapshot of 1 week of activity totally 36.4 BG of upload and it seems to be only for the 'smart' video from motion or detection which is even more strange. If this is ONLY the network traffic between cameras and NVR it might make sense since they're all currently set to VBR x 30 fps x Best Quality which is 1280-11520 Kb/s, so with less movement and detection the bitrate SHOULD at night and when there is less movement between frames.

I could change it to CBR and see if the traffic flow instead flatlines, but that won't really tell me if this is local or web traffic. Surely I can figure that out in the UniFi interface but haven't figured it out yet.

Mine clearly do not on an older 5216-16P-4K2SE

Just the handshake and occasional hi res photo attached to an email
 
Here’s what I see

Dahua P2P, at least on older NVRs, does not stream data/video through a dahua server. It acts as P2P was designed. Point to point. The P2P server simply acts as traffic cop

Unfortunately I can’t upload images but I see repeated regular handshakes with Dahua P2P servers from 350 bytes to 2-3 Kb

When I remotely view live or playback video from a remote NVR, I see direct P2P data between my phone and the known IP of the remote NVR. (Even though I’m using P2P, I still see the remote NVR IP on m my firewall log.)
One minute viewing was about 90-100MB of downloaded data from the remote NVR IP

The OP is seeing handshakes mostly, possibly some download video data and/or email.

Unless signed into the dahua account in DMSS, I don’t think any video data is being sent to Dahuas servers. And I’m not even sure that it does then
