Aqara_PM_Donie said in the G350 thread that the evaluation is complete and firmware development is planned over the next few weeks. This is a plan; the feature has not been announced as released.
For someone connecting a G350 to an NVR, “ONVIF supported” still leaves practical questions: which profiles are available, how local discovery and authentication work, and whether audio and events are exposed alongside video. It would also help to know whether an existing RTSP setup needs any changes.
When the firmware is released, I would like to see a short capability list and tested integration steps. Which of these would you check first on your NVR, and what would you want Aqara to document?
