A Complete Guide to Nest Motion Detection

Google Nest cameras offer some of the most intelligent and customisable motion detection available, helping you stay aware of what's happening at home without being overwhelmed by unnecessary alerts. Understanding how to use features like Activity Zones and smart alerts is key to getting the most out of your camera.

This guide provides a comprehensive overview of how to set up, optimise, and troubleshoot motion detection for your Google Nest cameras using the Google Home or Nest app.


## How Nest Detects Motion: Intelligent Alerts

Unlike simpler systems that just detect any movement, Nest cameras use powerful software to analyse their video stream in real-time. This allows them to understand what is moving.

  • Standard Detection: Even without a subscription, Nest cameras can detect general motion.
  • Intelligent Alerts (Nest Aware Subscription): This is where Nest truly excels. A Nest Aware subscription unlocks the camera's ability to differentiate between specific types of motion. You can choose to be alerted only for:
    • People: Detects when a person comes into view.
    • Packages: Notifies you when a package is dropped off or picked up.
    • Vehicles: Detects cars, vans, and other vehicles.
    • Animals: Can spot pets and other wildlife.
    • Familiar Faces: Can learn the faces of your family and friends and tell you specifically who it has seen.

## Setting Up and Customising Your Motion Settings

You'll configure your camera using either the Google Home app or the Nest app, depending on your device model.

### 1. Set Up Activity Zones

This is the most important step for controlling your alerts. Activity Zones are custom areas you draw on your camera's field of view to monitor specific places.

  1. Open your camera's settings and find "Activity Zones" or "Events" -> "Seen events".
  2. Tap to "Create Zone".
  3. Drag the points to draw a precise shape around an area of interest, such as your front door, a garden gate, or your driveway.
  4. Give the zone a descriptive name (e.g., "Porch" or "Driveway").
  5. You can create multiple zones for each camera. This is perfect for knowing exactly where activity is happening.

### 2. Customise Your Notifications

Once your zones are set, you can decide which events you want to be notified about.

  1. In your camera's settings, go to "Notifications".
  2. You can choose to receive alerts for events happening anywhere or only for events happening within your Activity Zones. For reducing unwanted alerts, choosing to monitor only within zones is highly recommended.
  3. Next, you'll see a list of event types (People, Animals, Vehicles, etc.). You can use the checkboxes to select exactly which events you want to generate a push notification to your phone. For example, you could choose to be alerted about people on your "Porch" zone, but not vehicles.

### 3. Set a Schedule

If there are certain times of day you don't need notifications (for example, when you are home), you can set a schedule to mute them automatically. This helps keep your notification history clean and relevant.


## Common Troubleshooting Steps

  • Not Getting Notifications?

    • Check Wi-Fi: Go to the camera's settings and check its "Device information" or "Technical info" to ensure it has a good Wi-Fi connection.
    • Check Notification Settings: Double-check that you have notifications enabled for the specific event types (e.g., "People") and zones you want to monitor.
    • Check Phone Settings: Ensure that your phone's operating system is not blocking notifications from the Google Home or Nest app.
    • Home/Away Assist: Check that your Nest Home/Away status isn't set to "Home," which might be configured to disable certain cameras or notifications.
  • Getting Too Many Notifications?

    • Refine Activity Zones: Make your zones smaller and more precise. Exclude any areas with constant, unimportant motion like a busy street or a neighbour's garden.
    • Be More Specific with Alerts: In your notification settings, be more selective. Instead of getting alerts for "All other motion," switch to only receiving notifications for "People" or other specific categories.
    • Reposition the Camera: Angle the camera to reduce the amount of public space in its view.

By leveraging Nest's powerful software features, you can create a highly accurate and informative security camera system that alerts you to what's important and ignores what isn't.

Frequently Asked Questions

Nest cameras use advanced video analysis to detect motion. They can differentiate between different types of events, and with a Nest Aware subscription, can even recognise familiar faces, packages, animals, and vehicles for smarter, more specific notifications.

You can manage all settings in the Google Home or Nest app. Select your camera, go to its settings, and look for "Events" and "Notifications." Here you can define what the camera looks for and when it should alert you.

Activity Zones are custom areas you draw on your camera's view. They let you monitor specific spots, like a doorway or a gate. You can then set up unique alerts for each zone, so you know exactly where the motion happened. This is key to reducing unwanted alerts.

A Nest Aware subscription unlocks intelligent alerts. This allows your camera to tell you if it saw a person, a package being delivered, an animal, or a vehicle, so you only get notified about the things you truly care about.

First, ensure your camera is online and has a good Wi-Fi connection. In the settings, check that notifications are enabled for the types of events you want to see (like "People"). Also, make sure you haven't set a schedule that mutes notifications during certain times.
