I'd like to know about TPU which is applied to the nest cam released in August.
What is the TPU?

And I heard that the new nest cam runs AI algorithm with twice as many pixels and frame rates through TPU. What does it mean by twice as many pixels and frame rates?

Hi there, 

Internally, the Nest Doorbell is powered by a 1.5GHz processor that features an ML hardware engine (TPU). On-device machine learning is a big part of Google’s new camera lineup, and it allows for free person, package, vehicle, and animal detection that doesn’t require a subscription. Processing occurs locally and therefore runs much faster. Also free is up to three hours of event video history (i.e., clips) and user-created activity zones. Hopefully that information helps. Please let me know if you need more information.
