DMSS works for Live View but not Playback

[Contadino]

I'm using an Empiretech NVR, Dahua camera and Pixel 6 Android phone.
Using DMSS on the phone I can see the live view but when i try to playback any IVS triggered recordings it doesn't work.
If I go to the NVR through a browser I can see live view and playback but the aspect ratio is way off.
Any ideas on how to see the playback videos?

Be more specific. How does it "not work"

 

[Contadino]

When I try to open an event recording I see a % indicator on the screen which increases from 1% and usually stops around 94%. Then the blue circling icon just keeps spinning. No recorded video ever plays.

Can you show a pic of your NVR playback?

 

[Contadino]

I have all these alarms but can't play any of them. Only Live View works.

Make sure you have the latest Firmware installed on all.
"aspect ratio is way off" ?? - System - Display- check resolution =1920x1080

How are you connected, wifi local to your NVR or remote via P2P?

If you have P2P enabled on your NVR and you have a profile on DMSS using the serial number, you should be able to play the clips if connected via P2P (disconnect from wifi)

If you only have a profile using a local IP via WiFi, you won’t be able to play the clips when you leave home (wifi)

I have two profiles in dmss

1-Home - using my local home lan IP address for my NVR. 192.168.1.x

2- Remote- using the NVR serial number via P2P

Sometimes using the serial# doesn’t work while home connected to my wifi. Thus 2 profiles.

Thanks Bigred. Very helpful. I'll work on it.

I’m also a fan of this for if the internet goes down in the middle of the night I can still get alerts.

Ok I'm trying to understand the DMSS behavior.
I created two profiles as you suggested, named them NVR AWAY P2P, and NVR HOME.
CASE 1: P2P enabled on the NVR, wifi is enabled on my phone, using DMSS on my Android phone.
See first screenshot. I can see my two profiles, in either one I can see live video, but there are no messages.
If I click on the Messages tab at the bottom I see only NVR AWAY. If I click on it I can see all the recorded events and can playback the videos. See second screenshot.

Case 2: P2P is disabled on the NVR, WIFI is enabled on my phone.
NVR AWAY P2P doesn't connect - went offline a little later.
NVR HOME live view works
Messages tab- NVR AWAY doesn't connect.

Case 3:
P2P disabled on NVR, wifi disabled on phone.
NVR AWAY P2P live view works
NVR HOME live view does not work
Messages tab- recorded videos can be played back.

There must be a way for me to playback recorded videos when I am on local wifi and P2P is disabled. Any recommendations?

Under the messages tab should I be able to see my NVR HOME profile?

Is it normal operation to not see any recordings under the DEVICE tab?

Are your cameras plugged into the NVR PoE ports or an external router?

If plugged into the NVR PoE ports, the first part of #3 sounds impossible, The camera relies on the NVR P2P connection
P2P disabled on NVR, wifi disabled on phone.
NVR AWAY P2P live view works

Beyond that, there have been previous threads about whether alerts work without P2P enabled on the NVR AND a Dahua account logged in in DMSS on the phone.

For me, I get push alerts/notifications on home wifi with P2P disabled on the NVR, but with no video/image pushed
The only way I get videos pushed is with P2P enabled on the NVR and DMSS logged into the Dahua account

I've concluded over the years that push notifications and alarm videos seem to be somewhat FW dependent. Others have had different results
