@sh809188 just wanted to report that I've had my first hiccup with this firmware. It had been running flawlessly. It looks like as of 23:42 last night, the video feed stopped. I did not notice until this morning. I also could not get the video feed to start from my phone on the Tapo app. But the doorbell was otherwise responsive. Ringing the bell sent the notification to our phones, etc. just no video. I was able to reboot the device through the app, and video resumed normally. I've since enabled "diagnostics" in the app, in case this happens again. Just wanted to pass this along. 

Just got this new doorbell and after searching how to enable the RTSP stream I found this topic. Any news when this function will be included in the stable firmware? And it is certain this will eventually be included?

Some other competing brands have also promised a RTSP stream for their doorbells years ago but never delivered on that promise. Seeing almost all Tapo camera have this functionality I'm really hoping TP-link will include this.
