The Google Nest Doorbell Wired (2nd gen) is one of the most capable video doorbells Google has ever made. It shoots in a tall 3:4 aspect ratio with HDR, supports genuine 24/7 continuous recording over a hardwired connection, and recognises people, packages, pets and vehicles without charging you a penny in subscriptions. The catch for UK buyers: Google has not officially released this model in the UK, and as of mid-2026 there is no confirmed UK launch date. This review covers every spec and feature so you know exactly what you would be getting — and what your actual options are if you are shopping for a wired Nest doorbell in Britain.
Quick verdict
The Nest Doorbell Wired 2nd gen is an excellent hardwired doorbell — arguably the best Google has produced. Its 145° diagonal field of view, HDR processing and always-on power make it a step above the battery variant. However, Google has restricted availability to the US and Canada since its October 2022 launch, leaving UK buyers in a frustrating position. If you need a wired Google doorbell in the UK right now, the closest equivalent is the original Nest Doorbell (wired, 1st gen) — also known as the Nest Hello — which remains widely available from UK retailers.

Video quality and camera performance
The 3:4 vertical format is a deliberate choice, not a compromise. While most doorbells shoot in widescreen 16:9, the taller frame lets you see a visitor from head to foot — which matters when you want to spot a delivered parcel at their feet, or confirm someone's identity rather than just their face and shoulders. The 960 × 1280 sensor may look modest on paper next to 2K cameras, but the HDR processing is what sets Nest apart from most rivals.
HDR applies to both day and night modes. In practice this means the camera handles the classic doorbell problem — a brightly backlit street behind a visitor standing in porch shadow — far better than cameras that clip highlights or underexpose faces. DXOMark ranked the 2nd gen wired Nest doorbell the highest-scoring camera doorbell they had tested at time of launch, citing its handling of high-dynamic-range scenes.
Night vision uses ten infrared LEDs at 850 nm, giving a useful range of around three metres. Footage is monochrome in darkness, unlike Ring's colour night vision on premium models. For most residential UK doorsteps with some porch lighting, the IR range is sufficient. Digital zoom reaches 6× without notable artefacting up to around 3–4×, useful for reading a delivery driver's badge or a vehicle registration plate.
24/7 recording and storage
Because the 2nd gen is hardwired rather than battery-powered, it can record continuously around the clock — a feature the battery variant cannot match. What you can access without a subscription: a rolling three-hour buffer of event clips, plus up to one hour of local storage if your internet connection drops.
To scrub through 24/7 footage, you need Google Home Aware Plus, which also extends event history to 60 days. The standard Google Home Aware tier (30-day event history) does not unlock the full continuous video timeline. In the UK, subscriptions are priced at £8/month (Standard) or £16/month (Advanced) as of 2026.
There is no SD card slot on the Nest Doorbell Wired 2nd gen — all footage is cloud-only except for the one-hour Wi-Fi outage buffer. If subscription-free local storage is a priority, see our roundup of the Ring vs Nest doorbell UK comparison for alternatives that offer on-device recording.
Smart detection: what is free and what costs extra
This is where the Nest Doorbell Wired 2nd gen genuinely stands out against Ring. Out of the box, with no subscription, you get:
- Person detection
- Package detection
- Vehicle detection
- Animal detection
- Activity zones (customisable alert regions)
- Two-way talk with noise cancellation
- Pre-recorded quick responses
Ring gates the equivalent smart detection behind its Ring Protect plan from £4.99/month. The Nest's on-device processing means detections are fast, private and do not depend on cloud round-trips to classify what the camera sees.
Familiar face detection — recognising household members and sending different alerts for known versus unknown visitors — requires a Google Home Aware subscription. Sound detection (breaking glass, smoke alarm, CO alarm) is also subscription-only.
Google Home integration and ecosystem
The Nest Doorbell Wired 2nd gen is managed entirely through the Google Home app. Setup involves scanning a QR code on the device and following in-app steps; wiring the doorbell to your existing chime circuit is the only part that may need an electrician if you are not confident with low-voltage wiring.
Once live, the doorbell streams to any Nest Hub, Nest Hub Max or Chromecast-enabled display when a visitor rings. Google Assistant can announce doorbell rings through Nest Audio or any Google speaker. The doorbell is also compatible with Alexa for basic announcements.
For Home Assistant users, the Nest Doorbell Wired 2nd gen is supported via the Google Nest integration using the Smart Device Management (SDM) API. The SDM API requires a one-time $5 developer fee from Google and grants access to live streams via WebRTC, motion events, person events and doorbell ring events. Familiar face events and package events are not exposed through the SDM API. Note that the WebRTC stream does not support server-side recording within Home Assistant, so it is best used for event-triggered alerts rather than continuous capture.
UK availability: what buyers actually need to know
The Nest Doorbell Wired 2nd gen launched in the US and Canada in October 2022. Google Nest Community threads from 2022 to 2026 show repeated questions about UK availability, with Google's official response consistently being that they have no news to share about a UK or European launch.
The situation became more complicated in late 2025 when Google launched a Nest Doorbell Wired 3rd gen in the US, featuring a 2,048 × 2,048-pixel sensor, Gemini AI integration and a 166° field of view — again with no UK release announced. This puts UK buyers two full generations behind the US product line for wired Nest doorbells.
Your practical options as a UK buyer in 2026:
- Nest Doorbell (battery, 2nd gen) — officially available in the UK, typically priced from £99.99 to £179.99 depending on retailer and sale. Shares the same sensor and free detection features, but cannot do 24/7 recording.
- Nest Hello (1st gen wired) — the original 2018 Google wired doorbell, still sold refurbished in the UK. Shoots in 1600 × 1200 with HDR and a 160° field of view. Older hardware but fully supported.
- Ring Video Doorbell Pro 2 — available in the UK at around £179.99. Shoots in 1536 × 1536 with head-to-toe framing, radar-based 3D motion detection, and colour night vision. Requires Ring Protect for smart detection.

Wiring requirements
The Nest Doorbell Wired 2nd gen requires an existing doorbell circuit supplying 16–24 V AC at a minimum of 10 VA, running at 50 or 60 Hz. Most UK homes built since the 1990s with a mechanical chime will have a compatible transformer, typically rated 8–24 V. If your transformer outputs less than 16 V AC or less than 10 VA, you will need to replace it before installing the doorbell.
UK doorbell transformers are low-voltage Class 2 devices and can legally be replaced as a DIY task without a registered electrician, provided the mains-side wiring is not disturbed. Google's installation guide recommends a 16–24 V AC / 10–40 VA transformer for reliable operation.
Should you buy one?
If you are in the UK and researching the Nest Doorbell Wired 2nd gen, the honest answer is that you cannot buy one through official channels as of June 2026. Some grey-market imports exist on eBay and via US forwarding services, but you would lose UK warranty cover, and the device's power supply optimisation is designed for 60 Hz circuits — though the spec sheet does list 50 Hz as supported.
For most UK buyers wanting a wired Google Nest doorbell experience, the Nest Doorbell (battery, 2nd gen) is the pragmatic choice — it shares the sensor, free detection features and Google Home integration, with the only meaningful trade-off being the lack of true 24/7 continuous recording. If wired 24/7 recording is essential and you are open to switching ecosystems, the Ring Video Doorbell Pro 2 delivers it in the UK with colour night vision and radar-based motion detection added on top.
