Thanks for the prompt reply. Seems like there might be some hope yet.  Thanks.

    1. What app/program are you using to stream the camera via the Onvif connection?

I'm using a modified version of the open source script quoted in my message, the essense of the code is something like:

pullpoint_req = pullpoint_service.create_type('PullMessages')
pullpoint_req.MessageLimit=10
pullpoint_req.Timeout = (dt.timedelta(days=0,hours=0,seconds=1))
while True:
    camera_messages = await pullpoint_service.PullMessages(pullpoint_req)  
    if camera_messages:
        for key in camera_messages: 
            print(f"\n--------------\n{key=}\n{camera_messages[key]=}\n--------------\n")
    else:      
        sleep(cfg.idleSleepSecs)
  
  2. Can you receive person-detected notifications on your phone or the Tapo app?

Yes that works.

    3. You can refer to the instructions below to stream the camera via iSpy and then check if the person detection notification via Onvif works.
        How to view Tapo camera on PC/NAS/NVR through RTSP/Onvif Protocol

I don't think there is an ispy for my platform (raspberry pi 4 raspbian/debian OS).

What I receive is a series of jason messages - which don't appear to have any attributes to distinguish motion-detections from person-detections - but I could be wrong on this as I'm just guessing.  Each jason message appears to be something like:

key='NotificationMessage'
camera_messages[key]=[{
   'SubscriptionReference': {
       'Address': {
           '_value_1': None,
           '_attr_1': None
       },
       'ReferenceParameters': None,
       'Metadata': None,
       '_value_1': None,
       '_attr_1': None
   },
   'Topic': {
       '_value_1': 'tns1:RuleEngine/CellMotionDetector/Motion',
       'Dialect': 'http://www.onvif.org/ver10/tev/topicExpression/ConcreteSet',
       '_attr_1': {
   }
   },
   'ProducerReference': None,
   'Message': {
       '_value_1': {
           'Source': {
               'SimpleItem': [
                   {
                       'Name': 'VideoSourceConfigurationToken',
                       'Value': 'vsconf'
                   },
                   {
                       'Name': 'VideoAnalyticsConfigurationToken',
                       'Value': 'VideoAnalyticsToken'
                   },
                   {
                       'Name': 'Rule',
                       'Value': 'MyMotionDetectorRule'
                   }
               ],
               'ElementItem': [],
               'Extension': None,
               '_attr_1': None
           },
           'Key': None,
           'Data': {
               'SimpleItem': [
                   {
                       'Name': 'IsMotion',
                       'Value': 'true'
                   }
               ],
               'ElementItem': [],
               'Extension': None,
               '_attr_1': None
           },
           'Extension': None,
           'UtcTime': datetime.datetime(2025, 1, 22, 7, 7, 53, tzinfo=datetime.timezone.utc),
           'PropertyOperation': 'Changed',
           '_attr_1': {
       }
       }
   }
}]

Perhaps I need to do some more research.  Any pointers are appreciated, but I fully understand that you might not have time to nursemaid every coder who decides to try and write a client.

Best Regards

Sorry, forgot to include a link to the open source python script in this thread it's TAPO-camera-ONVIF-RTSP

The Tapo C225 V2 supports Person detection notification via Onvif. 

I recently read a comment from a Tapo user that reported that, for some Tapo camera models, Person Detection notifications via ONVIF may require a subscription to activate the feature and that otherwise only basic notications are available.  Would you be able to confirm or deny this in respect to the C225?

> I have escalated your case to our tech team, and they will contact you via email to follow up on this case. Please wait patiently.

Thanks for raising the issue with you tech team, they have quickly repsonded with a new version of the firmware that fixes the issue.

Very impressive support! 

Many thanks.

I too am having this issue.  I can only get motion to pass via ONVIF.  I have am using Blue Iriis the latest version.  I installed Ispy's Agent DVR to see if it would get persom.  It also does not get it, only general motion detection.  I have my C225 v2 running the latest firmware.  I have never been able to get any of my Tapo cameras to pass anything other than general motion detection across ONVIF.  I am not sure which ones support it and with do not. C520WS, C220,C225,C120,C125 are my tapo cameras.  Do any of those support person detection over ONVIF?

My camera is the C225 v2.0 with firmware 1.1.0 250115 Rel.4764n.  I'm just using the camera with an sdcard and no cloud service subscription.

Since updating to this firmware, IsPeople detection events are definitly being passed in the ONVIF feed. 

My monitoring script is custom coded to parse the ONVIF that I see coming from the C225.  I've not tried any other software, so I'm unable to say whether other applications are able to parse the C225 ONVIF data.

The source for my own script is online at https://github.com/digitaltrails/onvifeye

In case it helps configure other applications, here is an IsPeople notification and I've also appended a normal IsMotion event.
