Why can I see live video in DMSS but no playback?

Live view does not prove the NVR recorded the earlier period. Check the same channel and time in local NVR Playback, then check DMSS date, channel and playback permission.

Where do I tap for DMSS playback?

Open DMSS > Device, find the NVR and tap Playback. Tap an empty tile, choose the exact camera channel, select the required date and move the timeline to the event.

Why does DMSS show the wrong day or time?

The app may have reopened on today, or the NVR clock, timezone or daylight-saving setting may differ from actual time. Verify the displayed date and document any recorder offset.

Can a shared DMSS user be blocked from playback?

Yes. Live-view and playback permissions can differ. The device owner should review the share and then the recipient should reopen the app and retest.

Will reinstalling DMSS restore missing recordings?

No. Reinstallation cannot recreate footage that was not stored on the NVR. Prove the recording locally before treating the phone as the fault.

What should I record before changing any settings?

For Dahua DMSS Playback Not Working, record the exact model, firmware if known, current status, error wording, screenshots and the last known working condition. Change one item at a time so you can identify what actually helped.

Should I factory-reset the equipment while troubleshooting?

Not as an early step. A reset can erase network, recording, user, account or integration settings. Use it only when you have a configuration backup, known credentials and a model-specific recovery plan.

How do I confirm the problem is genuinely fixed?

Repeat the original test, then check the relevant local and remote paths separately. If the problem was intermittent, monitor through the conditions that previously caused it and record the successful result.

Dahua DMSS Playback Not Working

If live view works in DMSS but playback does not, first prove whether the recording exists on the NVR, then check the exact app channel, date, permissions and remote path.

DMSS Playback Support

Summary

Use this guide when DMSS shows live cameras but its Playback screen is blank, displays the wrong time, misses some channels or fails away from the site.

Applies to

Dahua NVRs connected to DMSS
Owner and shared DMSS accounts
Sites where live view works but playback fails

Difficulty and time

Difficulty: Moderate

Estimated time: 15 to 35 minutes

What you will need

Local monitor and mouse on the NVR
Phone signed into the expected DMSS account
Incident channel, date and approximate time
NVR model and firmware if escalation is needed

What this guide covers

Prove the recording locally
Check HDD and recording schedule
Use the exact DMSS playback path
Separate permission and remote-network faults

Live view and playback use different parts of the system. A live image proves that the camera can be viewed now; it does not prove the NVR recorded the earlier period or that the app account can retrieve it.

This guide starts with the local recorder because DMSS cannot display footage that is absent from the HDD. Once local playback is proven, the phone checks become much faster and more meaningful.

Before you start

Choose one known recording as the test case. A recent period visible on the NVR is easier to diagnose than an uncertain old incident.

Write down the exact camera channel, date and time to test.
Confirm the phone date, NVR date, timezone and daylight-saving setting.
Check whether the user is the device owner or a shared user.
Do not delete the device from DMSS until local recording and ownership have been checked.

Important

Do not reinstall DMSS before proving the recording exists

Reinstalling the app cannot repair a failed HDD, missing recording schedule or absent footage.

For an important incident, protect the local recording first and avoid formatting or initialising the HDD.

Step 1: Prove the recording on the NVR

At the recorder, right-click Live View, open Main Menu, then Search or Video. Select the test camera, date and time and confirm that the timeline contains recorded footage.

Choose the exact channel, not only a nearby camera with a similar name.
Click the required date on the calendar and look for coloured recording blocks on the timeline.
Play the same period locally and note any difference between NVR time and actual time.
If the timeline is blank locally, move to recording schedule and HDD checks; the app is not the cause.

Step 2: Check HDD and recording configuration when local playback is missing

Open the NVR storage or HDD status page and confirm the disk is present and healthy. Then check the recording schedule for the affected channel.

Confirm the HDD is detected, initialised and not reporting an error. Do not initialise a disk containing footage you need.
Check that the channel had Continuous, General, Motion or event recording scheduled for the required period.
Confirm only the affected channel is not missing because of a camera outage or schedule gap.
After correcting configuration, make a new controlled recording; configuration changes cannot recreate old missing footage.

Step 3: Open the correct DMSS Playback screen

In DMSS, tap Device, locate the recorder and tap Playback. Tap an empty video tile, select the exact camera channel, then select the test date before moving the timeline.

Do not assume DMSS kept yesterday's date; some versions reopen on today.
Select one known channel first and wait for its timeline to load.
Move the timeline to the same displayed time that worked on the NVR. Account for any documented clock offset.
If playback works for the owner but not a shared user, review playback permission from the owner account.

Step 4: Separate account, phone and remote-network problems

When local NVR playback works but DMSS still fails, compare the owner account, connection type and phone permissions rather than changing recorder storage settings.

Test with the owner account where authorised, then compare the shared-user permissions.
Test once on site Wi-Fi and once on mobile data. A result that works only locally points to the remote or cloud path.
Confirm the NVR is online in DMSS and that upload bandwidth is not being saturated.
Update DMSS through the normal app store path and restart the app only after the recording and account checks are complete.

Worked example

Live view worked but yesterday was blank

Situation: The owner could see cameras live in DMSS but yesterday showed no recording for Camera 03.

Solution used: Local NVR Playback showed the recording under Channel 03. In DMSS the app had reopened on today and a similarly named Channel 04 was selected. Reselecting Device > Playback > Channel 03 and yesterday's date loaded the timeline.

Why this was chosen: The recording and remote path were healthy; the test was using the wrong app context.

Installation notes: The camera names were updated later so staff could distinguish the two views.

Common mistakes

Testing an uncertain incident instead of one known recent recording.
Leaving DMSS on today while searching for an earlier date.
Choosing the wrong channel because camera names are unclear.
Reinstalling DMSS before checking the NVR HDD and recording schedule.
Deleting and rebinding the recorder before confirming the owner account.
Assuming a shared user automatically has playback permission.

Troubleshooting table

Symptom	What to check	What to do next
Timeline is blank locally and in DMSS	No stored recording, HDD problem or schedule gap	Check HDD status and the channel recording schedule. Do not initialise a disk containing required evidence.
Local playback works but DMSS timeline is blank	Wrong date or channel, shared-user permission, NVR cloud path	Reselect Device > Playback, the exact channel and date, then compare owner and shared-user access.
Playback shows the wrong time	NVR timezone, daylight saving or clock offset	Document the offset and search the displayed NVR time that contains the event.
Playback works on Wi-Fi but not mobile data	Remote cloud path, account session or site upload problem	Confirm the NVR is online in DMSS and test the site upload and owner account path.
Only one channel has no playback	Channel schedule, camera outage or storage stream issue	Prove that channel locally and compare its schedule with a working channel.

When to contact support

Contact SecurityWholesalers support when the exact period plays locally on the NVR but still will not load in DMSS after the channel, date, owner account and mobile-data tests.

Send the order number, NVR model and firmware, DMSS app version, screenshot of the local Playback timeline, screenshot of DMSS Playback, affected channel and exact displayed time.
