Dahua Notifications Not Working
Troubleshooting
First question: what exactly is not working?
- The camera is detecting but no phone push arrives.
- Live view works but only some cameras notify.
- Notifications used to work and stopped after a phone or internet change.
- The owner expected motion alerts but the system is only set up for a different event type.
Where the fault usually sits
| Likely fault area | Typical symptom | First check |
|---|---|---|
| Event linkage | Camera records an event but no push is created | Check whether the event is linked to push or message output |
| Schedule | Alerts work only at odd times or never during testing | Check schedule and arming periods |
| Phone permissions | No pushes on one phone but another phone works | Check DMSS notification permission and battery restrictions |
| Recorder or camera online state | System seems fine locally but remote alerts never arrive | Check device online status and P2P health |
Sample scenarios
Example: a pharmacy rear-door camera is set up with human detection and local recording, but no one receives alerts after hours. The recorder event is working, but push linkage was never enabled for that rule and the manager assumed recording and push were the same thing.
Example: a cafe owner changes phones and suddenly no Dahua notifications arrive. Live view still works. The actual issue is the phone's battery management and notification permission, not the cameras.
What usually fixes it
- Confirm the site is testing the correct event type.
- Confirm the event is linked to push or notification output.
- Confirm the recorder or camera is online in the path DMSS expects.
- Confirm DMSS can run in the background and send notifications on that phone.
Relevant SecurityWholesalers Categories and Products
These Dahua categories are relevant because notification problems usually sit between the camera, recorder, and DMSS workflow rather than one part alone.
- Dahua NVRs - Notification logic often depends on the recorder path as much as the camera.
- Dahua CCTV cameras and kits - Useful if the notification problem leads back to the camera or event setup.

Frequently Asked Questions
-
Why are my Dahua notifications not working?
Usually because of push linkage, schedule settings, phone permissions, or the device not being properly online for app delivery.
-
Can the camera still be recording even if notifications fail?
Yes. Recording and push delivery are related but not identical functions.
-
Why do notifications fail after changing phones?
Often because DMSS permissions, battery restrictions, or app background behaviour changed on the new device.
-
Should I test motion, SMD, or another event type?
Test the exact event type the system is actually configured to use. Many notification faults are really test-method faults.
-
Can the NVR cause notification problems as well as the camera?
Yes. On recorder-based systems the event path, online state, and push linkage can depend heavily on the NVR configuration.
-
Which related page helps next?
Usually the DMSS troubleshooting page if the wider remote-view path is unstable, or the camera-not-showing page if the device itself is disappearing.
