Smart (e.g. Human) detections into MQTT stream

[UBWH]

My apolgies if already asked. (I did search this board).

I have:

• LightNVR running very well on Debian
• A Dahua camera that
  • is connected as a stream to LightNVR
  • has 'smart' detections (Human, Car)
  • has email notifcations enabled and I am getting emails direct from the camera with subjects like
    • IPC Message-10.1.1.135-Scene Changing
    • IPC Message-10.1.1.135-SMD(Vehicle)
    • IPC Message-10.1.1.135-SMD(Human)

LightNVR is connected to my MQTT server. I am getting messages like this successfully

{
 "stream":"Porch4k",
 "timestamp":1783920097,
 "count":1,
 "snapshot_topic":
 "lightnvrNeo3Plus/detections/Porch4k/snapshot",
 "detections":[
   {
   "label":"motion",
   "confidence":0.58570456504821777,
   "x":0.66666668653488159,
   "y":0,
   "width":0.3333333432674408,
   "height":0.3333333432674408,
   "track_id":0
   }
  ]
}

I am pretty sure (???) these detections are decided by LightNVR based on the video stream that it monitors.

My question is:

• How do I get an MQTT message that is triggered by the camera's internal, smart detecions (e.g. Human or Car)?

I don’t think LightNVR can pass Dahua’s Human/Vehicle labels through yet. Its ONVIF mode turns camera events into a generic motion MQTT event. To keep those labels, you’d need a separate Dahua-to-MQTT bridge, or let LightNVR do the person/car detection itself

Thanks for the reply. Not a show stopper.

I will have to live with the generic Motion events.
