Leo has had the Nest IQ camera for review this past week. It's an indoor 4K camera, but it doesn't necessarily stream 4K over the network. Because it has such a high resolution camera, it can zoom and pan, and also has face recognition. It can see a person coming to the house and identify whether or not it's someone familiar or a stranger. It's an expensive camera, but because it's a Google company, Nest cameras are among the most secure cameras on the market.
