sorry to bump this thread, i know it is unrelated, but after upgrading the Dahua H4C cameras, the PTZ is not working anymore from Frigate. i see the traffic is automatically redirect to port 443 for the request, i guess i would have to disable https on the camera, but just found it a little odd. also read that bitdefender flagged over the summer this type of camera for some security issues exactly for the onvif protocol. any help would be appreciated

getting this when running fovtest:

onvif.exceptions.ONVIFError: Unknown error: HTTPSConnectionPool(host='192.168.88.240', port=443): Max retries exceeded with url: /onvif/device_service (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1000)')))

UPDATE: managed to get PTZ working again in frigate by disabling the HTTPS for the camera under Settings -> System -> Safety -> HTTPS

You probably could have also set tls_insecure under onvif in your Frigate config for that camera.

You probably could have also set tls_insecure under onvif in your Frigate config for that camera.

The more you know, thank you the suggestion, I am exposing thr cameras to the www, so not having https is not a big deal for me.

UPDATE: Even with tls_insecure the ptz functionality is not working, seems like deactivating HTTPS resolves it for me

Hello, I tested my ONVIF PTZ camera using fovtest.py, and the PTZ control capabilities work correctly. The camera reports:

RelativeMove is supported (Pan, Tilt, and Zoom)

GetServiceCapabilities shows support for MoveStatus and StatusPosition

GetStatus returns valid position values, and MoveStatus transitions correctly

PanTiltSpeedSpace and ZoomSpeedSpace range from 0.0 to 1.0

PTZTimeout is valid

So the ONVIF PTZ control itself is working correctly.

However, when running Frigate PTZ autotracking calibration, Frigate runs from 0% to 100%, the camera moves during calibration, but the result ends with:

Autotracking calibration failed.

It looks like Frigate is unable to compute FOV calibration values from the returned position data.

Possible causes I’m considering:

The camera’s coordinate space for Pan/Tilt may not match the expected range.

The FOV math may assume normalized -1.0~+1.0 coordinates, but the camera returns a different scaling.

The PTZ status space:
space = http://www.onvif.org/ver10/tptz/PanTiltSpaces/PositionGenericSpace
may require special handling.

I confirmed that:

/ptz/relative_move works correctly

Move status transitions IDLE → MOVING → IDLE normally

No ONVIF permissions issues

I can provide full logs or a video if helpful.

Thanks in advance for your help!

You should open your own support discussion on the Frigate GitHub.

你应该在 Frigate 的 GitHub 仓库上发起你自己的支持讨论。

Okay, thanks.
