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. The night vision, which engages automatically, also beats the Ring's. Nest Hello uses HDR, which helps lighten shadowy areas while not blowing out bright areas. Sometimes the video looks a little artificial as a result, but the point is that you get a good look at everything in the frame, which is just what you'd want from a doorbell camera. When you're looking at the live view on your smartphone or tablet, you can pan and zoom using your fingers right on the image. The lens is fixed, so it's just digital panning and up to 8x of digital zoom. This is nice to have just in case you need it, but the default wide view was detailed enough for me.
