For most homes the Google Nest Doorbell (wired, 2nd Gen) is still the smarter buy, since it does nearly everything the Google Nest Doorbell (wired, 3rd Gen) does for less. The two share the same body and finishes, IP54 rating, dual-band Wi-Fi, HDR, free people, package, animal and vehicle alerts, custom ringtones and the same Google Home, Alexa, SmartThings and Home Assistant support, and neither includes a chime. What the 3rd Gen changes is the picture: 2K instead of HD, and a square 166 degree view instead of a tall 145 degree one, plus 6 hours of free event history against 3. The trade-off is that its free clips last up to 10 seconds, where the 2nd Gen's run up to 5 minutes. Stay with the Google Nest Doorbell (wired, 2nd Gen) to save money and keep longer free clips, and choose the Google Nest Doorbell (wired, 3rd Gen) if you want sharper, wider video at the door.

What the differences mean

Video resolution

The Google Nest Doorbell (wired, 3rd Gen) records in 2K, the Google Nest Doorbell (wired, 2nd Gen) in HD at 960 x 1280. The newer model is the one to read a face or a label from a distance.

Field of view

The Google Nest Doorbell (wired, 3rd Gen) sees 166 degrees diagonally in a square 1:1 frame, the 2nd Gen 145 degrees in a tall 3:4 frame. Both show visitors head to toe; the 3rd Gen also shows more of the porch to each side.

Free event history

Without Nest Aware, the Google Nest Doorbell (wired, 3rd Gen) keeps 6 hours of event clips and the 2nd Gen 3 hours. But the 3rd Gen's free clips are up to 10 seconds long, while the 2nd Gen's run up to 5 minutes, so the older model captures more of each visit.

Everything else

Identical on paper: same 131 x 42 x 28 mm body and 140 g weight, same IP54 rating, colors, dual-band Wi-Fi, HDR, smart alerts, one-hour offline recording buffer and platform support.

Which one to buy if

What owners say

Owners of both Nest doorbells praise the same strengths: smart alerts that separate people, packages, animals and vehicles instead of pinging at everything, a quick install on existing doorbell wiring and the ring showing up on a Nest Hub. Both groups also say the same thing about storage, that 24/7 history and familiar faces need a paid plan, and both note there is no chime in the box. Google Nest Doorbell (wired, 3rd Gen) owners single out a 2K image sharp enough to read package labels, near-instant live view and finishes that match the door trim; a few mention pauses in extreme cold and a need for strong Wi-Fi. Google Nest Doorbell (wired, 2nd Gen) owners, many coming from a Nest Hello, talk about much faster notifications and package picked-up alerts, and complain about tiny, fiddly wiring screws and a crash-prone web interface.

Upgrading from the Google Nest Doorbell (wired, 2nd Gen)?

Moving from the Google Nest Doorbell (wired, 2nd Gen) to the Google Nest Doorbell (wired, 3rd Gen) buys a sharper 2K image, a wider square view and a longer free history window. The body, finishes, alerts, apps and integrations stay the same, and free clips actually get shorter, from up to 5 minutes to 10 seconds. If your 2nd Gen already shows who is at the door clearly enough, there is little reason to replace it. Upgrade if you want more of the porch in frame or you keep zooming into blurry faces.
