I give a more in-depth response to this here:
Note that it’s even better now than when I explained things in that answer. I hope it continues to evolve and progress. It’s not for everyone, but some people find it to be fairly useful.
I don’t use it every single day, but I do use it on some of my cams fairly regularly just to get an overview of when something is abnormal and gives me an indication I might want to check it out.
I still wish I could get notifications about it when a particular camera is showing abnormal activity.
