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. It uses a 4:3 aspect ratio, for a squarer picture as opposed to some cameras' 16:9 wide screen view. The idea is that you'll be able to see packages on the ground in front of your door; but my whole doormat was out of view, so packages left there usually were, too. I found the picture clear and sharp — better than that of the Ring cameras, and with a larger field of view than the August Smart Doorbell Pro.
