Fix Lorex Notification Lag & Delayed Alerts on Your Phone

Experiencing a significant delay in your Lorex security notifications? Our guide provides practical, easy-to-follow solutions to fix notification lag.

Is this your issue?

  • Notifications arrive several seconds or even minutes after the event occurred.
  • The app shows the event timestamp correctly, but the push notification is late.
  • By the time I open the live view from a notification, the person or vehicle is gone.
  • Notification delays are worse for cameras that are far from the Wi-Fi router.
  • The notification arrives, but the associated video clip is not ready to view.
  • Alerts seem to come in batches rather than in real-time.
  • The lag is inconsistent; sometimes it's fast, other times it's very slow.

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

Tired of Delayed Lorex Notifications? Here’s How to Fix It

A security camera's value is tied to its ability to alert you to events as they happen. When you receive a notification for someone at your door five minutes after they've already left, the system isn't providing the security you need. Notification lag is a common and frustrating problem, but it's often solvable.

This guide will help you diagnose the root causes of your Lorex notification delays and provide practical steps to make your alerts arrive faster.

Step 1: Analyse Your Network Connection

The journey of a notification from your camera to your phone is complex, and the first point of failure is often your local network.

  • Check Wi-Fi Signal Strength: For Wi-Fi cameras, the connection to your router is critical. Open the Lorex app and go to Device Settings. Look for a "Device Health" or "Wi-Fi Status" section. The signal strength should be strong. If it's weak or poor, the camera will struggle to send data out quickly.
    • Solution: Move your Wi-Fi router closer to the camera, or install a Wi-Fi mesh system or extender to provide a stronger, more stable signal.
  • Test Your Internet Upload Speed: Your home internet's upload speed is what matters for security cameras. Run a speed test (you can find many free tools online) from a device connected to the same network. For a system with several HD cameras, you'll want an upload speed of at least 5-10 Mbps. If it's too slow, the video data can't leave your network quickly, delaying the alert.
    • Solution: Contact your internet service provider (ISP) to enquire about upgrading to a plan with a higher upload speed.

Step 2: Optimise Camera and App Settings

The settings you choose within the Lorex app can have a significant impact on notification speed.

  • Adjust the Sub-stream Quality: Your camera sends a lower-quality video stream (the sub-stream) for remote viewing and notifications to save bandwidth. Lowering this can speed things up. In the camera's settings, find the "Sub-stream" or "Remote Viewing" video settings. Change the resolution to a lower setting (e.g., from 1080p to 720p) and slightly lower the bitrate. This creates a smaller data packet that can be sent and processed much faster.
  • Refine Motion Detection Zones: If your camera is constantly being triggered by irrelevant motion (like trees swaying), it creates a queue of events that can slow down genuine alerts. Go to the motion detection settings and draw precise "Activity Zones" around the areas you care about, like your walkway or driveway, while excluding the busy street or your neighbour's garden.

Step 3: Check Your Smartphone's Settings

Sometimes the delay isn't at the camera's end, but on the device receiving the notification.

  • Disable Battery Optimisation for the Lorex App: Modern Android and iOS systems use aggressive battery-saving features that can delay notifications from apps that aren't actively in use.
    • Android: Go to Settings > Apps > Lorex. Find the "Battery" or "Power usage" section and set it to "Unrestricted" or "Do not optimise".
    • iOS: Go to Settings > General > Background App Refresh and ensure it is enabled for the Lorex app.
  • Check Notification Permissions: Ensure that the Lorex app has been given full permission to send you notifications, including "Critical Alerts" if the option is available on your device.

By methodically checking your network, camera settings, and phone configuration, you can identify the bottleneck and take targeted steps to eliminate frustrating notification lag from your Lorex system.

Frequently Asked Questions

Notification lag is typically caused by a combination of factors, including a weak Wi-Fi signal to the camera, high network congestion, slow internet upload speed from your home, or delays in the push notification services used by Apple (APNS) and Google (FCM). It can also be related to your phone's own connection.

Start by improving the Wi-Fi signal to your camera; consider moving your router closer or using a Wi-Fi extender. You can also try lowering the video quality (sub-stream) for notifications, as this uses less bandwidth. Finally, ensure the Lorex app has unrestricted background data access and is not being put to sleep by your phone's battery-saving modes.

Yes. A camera connected via an Ethernet cable directly to your router or NVR will almost always deliver notifications faster than a Wi-Fi camera. A wired connection is more stable and has lower latency, reducing one of the most common points of delay in the notification chain.

In most cases, no. The delay happens between the camera recording the event and the notification service delivering the alert to your phone. The quality of your mobile signal (4G/5G) will affect how quickly your phone receives the alert once it's sent, but it doesn't influence the initial processing delay from your Lorex system.
