Thank you for your reply!

>1.  Is the motion detection feature working when using the Tapo app?
Yes. The motion detection feature is working in the Tapo app.

>2. Can you watch the camera's live feed on the third-party program QNAP QVR Pro via the ONVIF connection?
Yes. Camera's live feed displays correctly in QVR Pro and QVR Pro Client.
The pan/tilt function also works properly.

I have 3 Tapo C520WS, but motion detection doesn't work on all of them.

thank you.

Hi,

I am also running into the same problem with the C520WS, so I just wanted to add my findings here as well.  I have 5 Tapo cameras (two C110, two C210, and one C520WS), and I recently set up Shinobi on my Raspberry Pi to monitor them for ONVIF events.  All 5 are able to transmit RTSP streams with no problems.  While the C110 and C210 cameras are also able to send ONVIF motion detection events as expected, the C520WS is not successfully sending motion events (events do show up in the Tapo app, however).

Just to make sure it was not a configuration problem with Shinobi, I also tried connecting to the C520WS using the Javascript package, node-onvif-events, as well as with "ONVIF Device Manager", and both fail to receive events as well, even though they can connect to one of my C210 cameras that I also tested and receive motion events from the C210.  node-onvif-events seems to fail with a "connection reset" exactly 10 seconds after the "PullMessage" request is sent to the C520WS, while ONVIF Device Manager reports the following:

I look forward to hearing a solution for this, whether it's new firmware or just some setting we need to do in the camera's configuration!

Thanks,

Roy

 Hi,
 

I've the same issues as well. I've 4 Tapo camera C520WS, C320WS, C210, C100. 
 

C520WS & C320WS not able to trigger the QVR Pro event record when there's motion detected from the Tapo app.
 

Another two C210 & C100 no issues, working as intended.

I also had a chance today to play with the new firmware on the C520WS.  While I am able to see events now in ONVIF Device Manager, including separate notices of motion vs. person, my particular issue, which affects the Shinobi recording software that I use, is still there, and I have followed up with details to the tech.

  @jp_kyoto Hello. I have purchased two C520WS and installed the newest firmware available 1.2.8, but the motion detection on the cameras does not trigger QVR PRO event. I had to revert to QVR handling the motion detection, but obviously the resolution has to be set to full HD. What did you do to gest it working? My cameras are set as ONVIF and profileS. Thanks for any support or idea you cold provide.
