Also another vote for Blue Iris. It's not the most user friendly software but it's awesome for the price. It can be tricky to get configured just right though...
I would love to hear if anyone has any recommendations for getting Blue Iris to do some of the features of this camera, such as compare face images against a Google Photos API?
I would also be curious to know if the cameras that move & try to auto focus are actually better. That seems like a potential plus but I could see wind blowing trees or a squirrel running causing the camera to focus on the wrong things. Maybe the Nest is smarter & only goes for certain objects that it can recognize... Motion sensor recording is kind of a pain to get right on my Blue Iris. Windy trees & spiders cause me to get a lot more video than necessary.
