New "Nest Cam IQ" indoor model has a 4K sensor. Video is still 1080p, but sensor allows for high-res snapshot images and some amount of digital pan/zoom.
They also added a face recognition feature (with subscription) that can be used for alerts for known people.
$299 price, ships in about a month, according to their website.
We have pre-ordered one for testing and will publish a report when it ships, but I wanted to put up this discussion for any preliminary comments or discussion on it.
