Nest Cam IQ
You don't want to need your security camera footage — but if you do, the most important thing is that it identifies who's been in your home. The Nest Cam IQ does it better than most. Thanks to its six-core processor and 4K sensor, it can detect unfamiliar faces, zoom in on them, and follow them through the scene. It also recognizes familiar faces, so it can tell you when your kids get home from school, and also has a built-in speaker for scaring off intruders or telling your dog to get off the couch.
