The camera does not support ONVIF when used as a standalone, battery-powered device. Due to hardware limitations, Reolink battery-powered cameras like this one do not support ONVIF protocols in standalone mode. ONVIF support is only possible when the camera is connected to the Reolink Home Hub, which is not a standard feature of this camera. This was confirmed in a test report that explicitly criticised the lack of ONVIF compatibility with this camera.
