@WyzeBaohua: I noticed something odd and exciting while adjusting the settings on a v3 cam today. This is observed only under the current beta app for Android v2.28.0 (b99) and only on 1 out of 30 v3 cams, all running current production firmware 4.36.8.15. It appears that implementation of this Wishlist item has somehow found its way to one of my v3 cams:
I’m confused as to how this highly desirable feature occurs only on 1 of my cams. If you pushed it somehow, please do not remove it. Push it to all of my cams! 
If the push was intentional, please let me know, as I have a few bugs to report. If you are as confused as I am, I’ll just wait until the feature is completed and enjoy being able to indepedently set AI Event types and AI Event type notifications on this cam. And kudos for implementing our ideas!
