Google puts Gemini inside your next Nest cam and speaker

Google is giving smart home devices the AI treatment. On Wednesday, the tech giant unveiled a refreshed lineup of Nest cameras, teased an upcoming Google Home smart speaker, and finally tackled the elephant in the room: a massive, much-needed overhaul of the Google Home app.

The hardware is built to feed data directly into Gemini, and Google is even teaming up with Walmart to bring the tech to budget cameras under $25.

Sharper cameras to feed multimodal AI

Google launched three new wired security devices: the third-generation Nest Cam Indoor ($99.99), the second-generation Nest Cam Outdoor ($149.99), and the third-generation Nest Doorbell ($179.99).

All three pack 2K HDR video, wider fields of view (up to 166 degrees on the Doorbell), and improved low-light sensors that keep video in full color longer at dawn and dusk. DXOMARK ranked all three first in their class for image quality. Out of the box, Google is doubling free event video history from three to six hours.

That extra resolution isn't just for human eyes. It gives Gemini the fidelity it needs to understand what is actually happening. Instead of generic "motion detected" alerts, users get precise notifications like "dog jumps out of playpen."

A new feature called Ask Home lets you search through video history using natural language, like asking what happened to a broken vase. Another feature, Home Brief, condenses hours of camera activity into a quick daily summary.

The new Nest cams are available immediately in multiple regions, though Gemini features roll out first to the US, Canada, the UK, Ireland, and Australia, with others following in early 2026.

Walmart budget cameras and a new speaker

Google is not keeping Gemini exclusive to premium gear. In a partnership with Walmart, it launched the onn Indoor Camera Wired for $22.96 and the onn Video Doorbell Wired for $49.86. Both offer 1080p feeds and integrate directly with the Google Home app, tapping into Gemini features via a Google Home Premium subscription.

Google also revealed the new Google Home Speaker ($99.99), designed with custom silicon to handle Gemini conversations faster. It features 360-degree sound, a glowing light ring indicating when the AI is listening or reasoning, and can pair with the Google TV Streamer for a surround-sound setup. It launches in Spring 2026, though existing Nest and Home speakers will get an early access Gemini update later this October.

Fixing a notoriously sluggish app

Perhaps the biggest news for long-time users is the complete rebuilding of the Google Home app. Anish Kattukaran, chief product officer at Google Home and Nest, candidly admitted to reporters that the app "has not been the experience that we’ve always wanted it to be."

Google claims the updated app starts up 70% faster, suffers 80% fewer crashes, and loads camera feeds 30% faster with a sixfold increase in timeline scrolling frame rate. The interface has been streamlined into three tabs: Home, Activity, and Automation.

The update also finalizes the decade-long migration of legacy Nest app features into Google Home, bringing over controls for older thermostats, Nest Protect smoke detectors, and door locks.

Why it matters

For everyday homeowners, this finally solves the worst part of smart security: alert fatigue and endless video scrubbing. Being able to ask plain-English questions to locate an event turns passive surveillance footage into an actual database you can query in seconds.

Strategically, Google's move into budget hardware with Walmart is a brilliant land grab. Premium hardware like Nest alone cannot win the volume game against cheap third-party cameras. Offering a $23 camera that hooks into Gemini helps Google lock users into its software subscription ecosystem while putting immense pressure on Amazon's Ring and Blink lineups.

However, there are real trade-offs. The staggered timeline is frustrating, with the new speaker delayed until Spring 2026 and international Gemini rollouts lagging behind. More critically, piping high-definition, 2K home footage into a multimodal cloud model raises the privacy stakes significantly. Even with hardware encryption and status LEDs, convincing mainstream households to let an advanced AI constantly summarize and interpret their private living spaces remains a major psychological hurdle.
