To set up motion detection alerts, turn on event notifications for the camera in its app, allow notifications for that app in your phone’s settings, choose the motion or smart-detection events you want, and refine the camera’s detection zone. Then test it by walking through the monitored area. Exact steps and available features vary by camera, app, model, subscription, and region.
Before you start
Make sure the camera is powered, charged if it runs on battery, and online in its manufacturer’s app. You’ll need access to the app and to the phone where you want alerts to appear.
Many systems configure alerts separately for each camera. Google notes that Google Home app settings are off by default, and that available alert options depend on the camera and subscription. Check each camera you want to monitor rather than assuming one change applies to your whole system. Google Home and Nest: Camera and doorbell alerts
Set up alerts in the camera app
- Open the camera’s settings. In the manufacturer’s app, select the camera or doorbell, then open its settings or notification controls. Menu names differ between apps.
- Turn on event notifications. Enable alerts for that specific camera. If there is a separate setting for recording events and sending notifications, enable the notification setting as well.
- Choose what should trigger an alert. Select all motion if you want broad coverage, or choose supported categories such as people, vehicles, animals, or packages. Category detection is not available on every model, and may depend on a subscription or region.
- Allow notifications on your phone. In the phone’s operating-system settings, find the camera app and allow notifications. The app’s camera alert setting and the phone’s permission are separate: both need to be enabled for a phone notification to arrive.
- Set a motion or activity zone, if available. Mark the part of the camera’s view you want to monitor and exclude areas likely to trigger irrelevant events, such as a busy street or moving branches. A zone narrows the area being monitored; it does not guarantee that every movement inside it is relevant.
How the settings vary by camera system
These systems illustrate why there is no single set of tap-by-tap instructions for every camera. Check the manufacturer’s current instructions for your exact model and app.

Google Nest
Manage camera and doorbell alerts in the Google Home or Nest app. Available event options depend on the device and Google Home Premium status, and alerts need to be configured for each camera. Activity Zones can focus alerts on a marked area. Google describes newer supported cameras as using on-camera algorithms, while general motion detection can also respond to movement outside recognized categories, including minor background motion such as swaying branches. Features are not identical across Nest models. Camera and doorbell alerts · How Nest cameras detect sound and motion
Arlo
Arlo Smart Detection can offer categories such as people, packages, vehicles, animals, and fire, but Arlo says Smart Detection requires an Arlo Secure Plan and plans vary by region. Activity Zones focus detection on selected areas; movement inside a zone can still produce unwanted alerts. Arlo Smart Detection setup · About Arlo Activity Zones

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Test the alert and tune it
- Walk through the part of the view you intend to monitor, then check whether the camera recorded the event and whether your phone received a notification.
- If the camera recorded the event but no notification arrived, check the camera’s event-alert setting and the app’s notification permission on your phone.
- If the event was not recorded, check that the camera is powered, charged if applicable, and online. Then confirm that the relevant event category is enabled for that camera.
- If alerts are too frequent, narrow the motion zone or turn off broad all-motion alerts if the camera offers more specific categories. Adjust the zone and test again.
- If alerts arrive late, first establish whether the event appears in the camera’s history. If it does, check the app and phone notification settings; if it does not, review the camera’s connection, event settings, and detection area.
Google’s troubleshooting guidance covers too many or too few alerts, false positives, and delays; the exact phone permission path depends on the operating system. Troubleshoot Nest camera alerts and notifications
