Wired smart video doorbell with HDR camera in 3:4 portrait aspect ratio (960x1280) for head-to-toe and package visibility. On-device AI for person, package, animal, and vehicle detection.
常见应用
Requires 16-24 VAC transformer (10 VA minimum) — verify existing wiring before installation. Connects via dual-band WiFi. On-device AI processing means basic alerts work without a subscription. 3:4 portrait orientation shows more vertical space than typical 16:9 doorbells — designed to see packages on the ground and faces at the door.
Research Notes
1. Overview
The Google Nest Doorbell (Wired, 2nd Gen), model GA02767-US, is Google's hardwired smart video doorbell. Its standout feature is on-device machine-learning detection — it distinguishes people, packages, animals, and vehicles locally and includes 3 hours of free event history with no subscription (a key contrast with Ring). Video is a tall 3:4 portrait (960×1280) HDR view (head-to-toe + package view) with up-to-10 ft night vision, two-way audio, managed in the Google Home app. It's hardwired (16–24 V AC, 10 VA min) and, unlike the Battery model, is always powered. Wi-Fi is dual-band (a plus over 2.4 GHz-only rivals).
2. User Sentiment
Praised for the no-subscription on-device detection, the clear tall 3:4 video, dual-band Wi-Fi, easy Google Home integration, and always-on wired power. Common criticisms: it needs existing doorbell wiring (16–24 V AC / 10 VA transformer), the Home app's evolving feature set, and that longer/24-7 event history (Nest Aware) is a paid add-on. The 3:4 portrait aspect is great for packages/people but shows less width.
3. Real-World Applications
Wired front-door monitoring with package/person alerts, two-way talk, and Google Assistant announcements on Nest speakers/displays — always powered, with 3 hr of free event history.
4. Technical Specifications
- Type: hardwired smart video doorbell (2nd Gen)
- Video: 960×1280 (3:4 portrait) HDR, 145° diagonal FOV, night vision (~10 ft)
- Detection: on-device ML — person / package / animal / vehicle; 3 hr free event history
- Power: hardwired 16–24 V AC (10 VA min); existing chime compatible
- Connectivity: Wi-Fi dual-band (802.11 a/b/g/n/ac)
- Ecosystem: Google Home, Google Assistant; longer history via Nest Aware
- Color: Snow
5. Ordering & Compatibility
Requires existing 16–24 V AC doorbell wiring (10 VA transformer). Works with Google Home + Nest speakers/displays; 24-7/longer recording needs Nest Aware. The battery counterpart is the Nest Doorbell (Battery), GA01318 (#377).
6. Hackability & Known Issues
- Hackability: limited/cloud-gated. More local processing than Ring (on-device detection), but integration is via Google's SDM (Smart Device Management) cloud API — Home Assistant's Nest integration works but needs a Google Cloud dev project + cloud auth; no supported fully-local mode, not DIY-flashable.
- Known issues: needs a compatible transformer/wiring, subscription (Nest Aware) for extended history, 3:4 portrait shows less width, and app/feature churn as Google migrates Nest into Google Home.
