Google Nest Doorbell (Wired, 2nd Gen) Review: The Case for Never Missing a Moment

There's a particular frustration that comes with checking your doorbell footage and finding... nothing. The delivery driver came, rang the bell, and left before your battery-powered doorbell woke up from its power-saving slumber. The Nest Doorbell Wired exists to eliminate that frustration entirely. With 24/7 continuous recording, this doorbell doesn't sleep, doesn't miss, and doesn't care how many times the neighborhood kids ring and run. If it happened at your door, it's on tape.

What Makes the Nest Doorbell Wired Different

Let's address the elephant at the front door: why pay the same price for a wired doorbell when the battery version offers more flexible installation? The answer is deceptively simple: continuous recording changes everything about how a smart doorbell actually functions.

Google's second-generation wired doorbell represents a maturation of their smart home strategy. The original Nest Hello was good. This is better in ways that matter: improved HDR video, more reliable connectivity, and the same on-device AI processing that makes their cameras so responsive.

Key Features of the Nest Doorbell Camera

HDR Video That Actually Matters

Here's a scenario every doorbell owner knows: the sun is setting, casting that beautiful golden light across your porch, and your visitor's face is a shadowy silhouette. Traditional cameras pick one or the other - expose for the bright background and lose the face, or expose for the face and blow out everything else. The Nest Doorbell Wired's HDR processing handles both simultaneously. Faces stay visible even with bright backlighting. Package labels remain readable in direct sunlight. Night vision transitions smoothly without that jarring black-and-white switch that screams "security camera footage."

On-Device AI: Intelligence Without the Wait

When Google says "on-device AI," they mean the doorbell itself is doing the thinking. It doesn't upload video to some server farm to figure out whether that's a person or a tree branch. The classification happens instantly, locally, on the device. The practical benefit? Faster alerts. Fewer false positives. And a subtle privacy advantage - your footage isn't being analyzed in the cloud just to tell you a leaf fell.

The AI distinguishes between:

• People: Human-shaped beings at your door (revolutionary, we know)
• Packages: Boxes, envelopes, anything that looks delivery-shaped
• Animals: That neighbor's cat that keeps visiting your porch
• Vehicles: Cars, trucks, delivery vans in view

Wired vs Battery: The Honest Comparison

This is the question everyone asks, and it deserves a thorough answer. Both versions of the Nest Doorbell have their place. The right choice depends on your specific situation, your existing doorbell wiring, and how much you hate charging things.

When Wired Makes Sense

Choose the wired version if:

• You have existing doorbell wiring (most homes built after 1950 do)
• Missing footage is unacceptable - you need that continuous timeline
• You're tired of charging devices (aren't we all?)
• Your front door sees heavy traffic that would drain a battery quickly
• You want the complete picture, not just motion-triggered clips

When Battery Makes Sense

The battery version wins if:

• No existing doorbell wiring and you'd rather not install any
• You're renting and can't modify the property
• Your doorbell location has no nearby power source
• Power outages are common in your area (battery provides backup)

Pros and Cons

Installation Guide

Installing the Nest Doorbell Wired is straightforward if you have existing doorbell wiring. If you're replacing an old doorbell, you're probably looking at 20-30 minutes. First-time installations without existing wiring require an electrician.

Before You Start

• Verify your transformer output: 16-24V AC, minimum 10VA
• Download the Google Home app and create an account
• Locate your circuit breaker for the doorbell circuit
• Have a Phillips screwdriver ready

Step-by-Step Installation

1. Turn off power at the circuit breaker. Don't skip this step - doorbell voltage is low but the transformer connects to line voltage.
2. Remove your old doorbell. Unscrew the mounting plate and disconnect the two wires. Don't let them fall back into the wall (tape them temporarily).
3. Check wire compatibility. The Nest connects to standard doorbell wiring. If your wires are in good shape, you're ready.
4. Install the mounting bracket. Use the included angle plate if your doorbell area isn't flat. The bracket accepts standard doorbell wire placement.
5. Connect the wires. Loosen the screws on the back of the doorbell, insert the wires, and tighten. Polarity doesn't matter for AC doorbell wiring.
6. Attach the doorbell to the mounting bracket. It clicks into place securely.
7. Restore power at the circuit breaker.
8. Complete setup in the Google Home app. Scan the QR code, connect to Wi-Fi, and configure your preferences.

Chime Compatibility

The Nest Doorbell Wired works with most existing mechanical and electronic doorbell chimes. During setup, the app will help you configure the correct chime type. If your existing chime isn't compatible, you can:

• Use Google Home speakers/displays as your chime (they announce visitors)
• Rely on phone notifications
• Purchase a compatible plug-in chime

Google Home Integration

If you're invested in Google's ecosystem, the Nest Doorbell becomes more than a camera - it's a connected part of your smart home. The integration is deep, responsive, and genuinely useful.

Voice Commands That Work

• "Hey Google, show me the front door" - displays live feed on Nest Hub or Chromecast
• "Hey Google, who's at the front door?" - announces visitor if familiar face is recognized
• "Hey Google, talk to the front door" - opens two-way communication
• "Hey Google, announce to the front door" - broadcasts your voice outside

Automation Possibilities

With Google Home routines, your doorbell can trigger actions throughout your home:

• Someone at the door? Pause the TV and show the live feed automatically
• Package detected? Send a notification to every family member's phone
• Doorbell pressed after sunset? Turn on porch lights and interior entry lights
• Familiar face arrives? Unlock smart locks automatically (requires additional setup)

Nest Aware Subscription Options

The doorbell works without a subscription - you get 3 hours of event history free. But to unlock continuous recording and extended history, you'll need Nest Aware.

How It Compares to the Competition

Final Verdict

Who Should Buy This

• Google Home users who want deep ecosystem integration
• Anyone with existing doorbell wiring who's tired of battery charging
