Nest AwareA Nest Aware subscription is technically optional, and you get a 30 day trial. But if you choose not to subscribe, you lose the facial recognition feature, continuous recording and video history, close ups, customizable activity zones, and the ability to upload clips and create time lapses online. You'll still be able to see the live view and talk over the two way speaker, get motion and people alerts just without familiar faces being named, see snapshots of events from the past 3 hours and be notified when someone rings the bell. Nest Aware starts at $5/month or $50/year to keep a five day video history, plus up to 3 hours of stored clips. Higher tiers provide up to 30 days of video history. PerformanceThe Nest Hello's camera has a resolution of 1600 x 1200, and covers 160 degrees of view.
