- Notifications not enabled for the camera in the app
- Phone OS notifications blocked for Lorex
- Motion or smart detection not triggering a push
Problem Description
Your Lorex camera records motion but the Lorex Home app sends no push alerts, or they arrive late. This is usually notifications not enabled per camera, the phone's notification permission, or motion/detection not set up to trigger a push.
Why This Happens in Real Homes
Missing Lorex alerts trace to a chain that has to line up: the per-camera notification toggle in the app, the phone's OS notification permission, and a detection setting that actually triggers a push. Any one off and the camera records perfectly while your phone stays silent. It's easy to have notifications on for one camera and off for another, which is why some alert and others don't.
Enable notifications on each camera under Device Settings, allow notifications for Lorex in your phone settings, and make sure motion or smart detection is on to generate the alert. If pushes arrive late, turn off push-notification thumbnails - Lorex's own tip for speed. On Android, set Lorex to Unrestricted so battery optimization doesn't kill it, and check Do Not Disturb isn't muting it. That covers nearly every silent-alert case.
Symptoms
- No push alerts on the phone
- Motion records but no notification
- Alerts arrive very late
- Notifications stopped after an app update
- Alerts work on one phone, not another
- No alerts when the app is closed
- Only some cameras notify
- Doorbell or camera press sends nothing
Recognize these? Here's what usually causes it.
Common Causes
- Notifications not enabled for the camera in the app
- Phone OS notifications blocked for Lorex
- Motion or smart detection not triggering a push
- Push-notification thumbnails delaying delivery
- Recorder or camera offline in the app
- Battery optimization killing the app in background
- Do Not Disturb silencing alerts
- Old app or phone software
Most fixes happen in the first 3 steps.
On Android, set Lorex to Unrestricted in battery settings - background battery optimization is a top reason alerts only arrive when the app is already open.
Tools & Requirements
Step-by-Step Solution
Enable Notifications per Camera
In the Lorex app, notifications are set per device. Under your recorder, swipe left and tap a camera, then from its Live View tap the Device Settings icon, tap Notifications, and enable it. Each camera has its own toggle, so one can be off while others alert.
Allow Notifications on the Phone
Go to your phone's Settings, find the Lorex app under Notifications, and confirm notifications are allowed, including lock-screen and banners. A blocked OS permission stops every push, and a phone update can quietly reset it.
Tie Alerts to Motion or Smart Detection
A push only fires when something triggers it. Make sure motion detection - or person/vehicle detection on supported cameras - is enabled for the camera, so events actually generate a notification rather than just recording silently.
Disable Push Thumbnails if Alerts Lag
If notifications arrive slowly, Lorex recommends turning off push-notification thumbnails. The thumbnail image takes time to attach and send; disabling it makes the alerts arrive faster, just without the preview picture.

Confirm the System Is Online
A recorder or camera that's offline can't send alerts. Check that your NVR shows connected in the app and the camera is live, since notification gaps usually line up with the system being offline.
Exempt Lorex From Battery Optimization
On Android especially, battery optimization closes the Lorex app in the background so pushes stop arriving when the app isn't open. In your phone's battery settings, set Lorex to Unrestricted or exclude it from optimization.
Turn Off Do Not Disturb
A focus mode, Do Not Disturb, or bedtime schedule can silence Lorex alerts even when they're delivered. Add Lorex as an allowed app, or disable the mode during the hours you need alerts.
Update the App and Escalate
Update the Lorex Home app and your phone's software so versions match, then retest. If a fully-permitted phone with the system online and detection on still gets no alerts, sign out and back in or reinstall the app, then contact Lorex.
Quick Solutions
Still having issues? This is usually the deeper cause below.
Notification delays almost always return after a major iOS or Android update — background app refresh gets reset to restricted on every major OS version.
Decision point
If the fix does not hold, check the matching replacement before another reset cycle.
This is the most relevant replacement path for this Lorex guide. Use it only if the steps above failed, the issue returns, or the part cost is too close to replacing the device.

Notification delays over 2 minutes are almost never the device's fault — background app restrictions quietly re-enable themselves after every OS update.
