RTSP Stream From MV12W To Dahua NVR

[RAID5]

Hello I wonder if any of you guys can help me please, we have a 5 second lag using the Apple TV for Videowall.

The camera is used for an operational purpose and the delay is unacceptable.

We dont wish to put a pc in with VLC player.

Has anyone successfully set up a meraki camera on a Dahua NVR? (model dhi-NVR4104 )

There are no clear options for RTSP and i only have a field for the IP not the full RTSP URL of the camera.

I have tried this to no avail!

I get slightly different options if i set the manufacturer to ONVIF I can set custom RTSP port to 9000 but the camera status wont show connected & meraki cameras dont support ONVIF. 

Thanks in advance!

You cannot connect Meraki Cameras to third-party NVRs. Meraki RTSP only supports live video.

External RTSP - Cisco Meraki Documentation

Use Case
External RTSP allows administrators to use third-party software that processes RTSP streams for additional analytics beyond the Meraki dashboard. It also enables the integration of MVs into existing legacy camera deployments.

The only way I was able to get an RTSP live feed working with any software was by using Home assistant and setting up RTSP devices but be aware that MV devices only allow 2 simultaneous RTSP streams.

Apple devices are a known issue with the lag. Specifically, it doesn't support LL-HLS so it will be delayed by 5-10 seconds. Our solution was to use a NUC with the Meraki vision app. Lag is about 1 second.

On a related note, if you are US or five eyes, I would recommend not using Dahua. They are banned from most western countries for a variety of reasons.

Dahua is available in NZ which is part of the 5 eyes.

Hmm I stand corrected. I still wouldn't use it though!

Thanks for the replies everybody, we are currently looking at other options, possibly NUC etc. Very helpful thanks again

In my opinion, the only reliable options are to use Meraki cloud streaming to stream data to the DVR. Unfortunately, there is no built-in solution for low latency integration.

Esto no funcionará como quieres.

Las cámaras Meraki MV no son compatibles con ONVIF. Los NVR Dahua dependen en gran medida de ONVIF o de perfiles de cámara predefinidos. Si el NVR solo te permite introducir una IP y no una URL RTSP completa, estás atascado. La transmisión RTSP de Meraki requiere la ruta completa y las credenciales.

Incluso cuando RTSP funciona, Meraki solo ofrece RTSP de máximo esfuerzo. En Penalty Shoot Out Casino cada tiro https://penalty-shootout.es/ cuenta y cada acierto se paga mejor. Tiene buffering y no está diseñado para una latencia ultrabaja. Unos pocos segundos de retraso son normales, y Apple TV añade aún más retraso.

Por lo tanto, un NVR Dahua no se conectará de forma fiable ni solucionará el retraso. Si necesitas vídeo casi en tiempo real, básicamente estás limitado al propio videowall de Meraki, un decodificador de hardware compatible con URL RTSP completas o aceptar que Meraki no está diseñado para una visualización operativa con latencia cero.
