Unifi Delayed Notifications: How to Get Alerts Faster

Receiving Unifi Protect notifications too late? Our guide helps you troubleshoot network latency, server performance, and app settings for timely motion alerts and doorbell rings.

Is this your issue?

  • Notification arrives several seconds or minutes after an event occurs
  • The person or vehicle is gone by the time the alert is received
  • Alerts are timely on local Wi-Fi but significantly delayed on mobile data
  • The Unifi Protect controller (NVR, Cloud Key) shows high latency or CPU usage
  • The mobile app is slow to connect and receive updates from the system
  • Push notification services on your phone seem to be experiencing general delays
  • Doorbell ring notifications are particularly slow to arrive

If you're experiencing any of these symptoms, the guide below will help you resolve them.

How to Fix Delayed Unifi Protect Notifications

Timely notifications are the cornerstone of any security camera system. When a Unifi Protect notification for motion or a doorbell ring arrives seconds or even minutes late, it can render the alert useless. If you're experiencing this delay, the issue typically lies within your network, the Unifi Protect controller, or your mobile device's settings.

This guide will provide a step-by-step process to diagnose and resolve notification delays in your Unifi Protect system.

## Step 1: Analyse Your Network Environment

The journey of a notification from your camera to your phone is complex. A delay at any point in the chain can slow down the entire process.

Controller and Internet Connection

The Unifi Protect controller (whether it's a Cloud Key Gen2+, UDM Pro, or UNVR) is the brain of your system. Its connection to the internet is critical.

  1. Check Controller Health: In your Unifi dashboard, check the CPU and memory load of your controller. If the CPU load is consistently high (more than 80%), it may be struggling to process video and send alerts promptly. This can happen if you have many cameras or overly sensitive motion detection settings.
  2. Internet Upload Speed: Your controller needs a stable, low-latency internet connection with sufficient upload speed to send notification data to the cloud and then to your phone. Run a speed test from a computer on the same network to verify.
  3. Local vs. Remote Latency: Are notifications delayed only when you are away from home (on a mobile network) or also when your phone is connected to the same local Wi-Fi as the controller? If the delay is only on mobile data, the issue is likely with the remote connection or your mobile carrier.

Step 2: Optimise Unifi Protect Settings

Misconfigured settings within the Unifi Protect application can lead to processing delays or an overwhelming number of events that bog down the system.

Fine-Tune Motion and Smart Detections

  1. Reduce Motion Sensitivity: If your motion sensitivity is too high, the system gets flooded with insignificant events (like leaves blowing), which can create a queue and delay important alerts.
  2. Refine Motion Zones: Ensure your motion detection zones are drawn tightly around the areas you care about. Exclude public streets, busy footpaths, or trees that move in the wind.
  3. Use Smart Detections: This is a key feature. Instead of using generic motion detection, configure your alerts to trigger only for "Person" or "Vehicle" detections. This offloads processing to the AI and dramatically reduces the number of events the system needs to handle, leading to faster notifications for what truly matters.

Check Notification Settings

  • Review Alert Schedules: In the Unifi Protect app, under Settings > Alerts, ensure you haven't accidentally configured a schedule that silences notifications during certain times.
  • Update Everything: Make sure you are running the latest versions of the Unifi Protect application on your controller and the Unifi Protect app on your mobile device. Updates frequently include performance improvements.

Step 3: Troubleshoot Your Mobile Device

Sometimes the delay isn't caused by Unifi at all, but by how your smartphone handles notifications.

Disable Battery Optimisation

This is a very common cause of delayed alerts, especially on Android devices.

  • Android: Go to Settings > Apps > Unifi Protect > Battery. Set the battery usage to "Unrestricted". This prevents the operating system from putting the app to sleep to save power.
  • iOS: Go to Settings > General > Background App Refresh and ensure it is enabled for the Protect app.

Check 'Do Not Disturb' and Focus Modes

Ensure that the Unifi Protect app is not being silenced by any 'Do Not Disturb', 'Sleep', or 'Focus' modes you may have configured on your phone. You can often add specific apps as exceptions to these modes.

By systematically checking the path from your controller to the internet and finally to your phone, you can identify the bottleneck and restore the speedy, reliable notifications that make Unifi Protect an effective security tool.

Frequently Asked Questions

Delays are often caused by network latency between your Unifi controller (like a Cloud Key or NVR) and your mobile device, or high processing load on the controller itself.

Ensure your Protect controller has a strong, stable internet connection. Check the notification settings in the app and consider optimising motion zones to lower the processing load.

Yes, an outdated Unifi Protect app can have bugs or performance issues. Always ensure you are running the latest version of the app on your mobile device and the latest Protect version on your controller.

Yes. Go to your phone's settings and find the Unifi Protect app. Ensure that it is exempt from any battery optimisation or 'deep sleep' features that might prevent it from running in the background.
