Camera visible on HIK-connect app, but error on door station display

[ivv]

Hi!

(not sure where to post this)
I live in an apartment building where is installed a HikVision intercom (with indoor stations in every apartment) and a Dahua surveillance camera system.
We managed to reset the all the passwords and now we are trying to connect the Dahua IP cameras to HikVision indoor stations. We verified all the IPs and made sure there are no conflicts. We used ONVIF protocol and added one of the Dahua IP cameras on the HikVision indoor station. The settings are good, we can see the live view from that camera using the HikVision app (from anywhere), but when we tap on the indoor station and choose the camera, there is only an error saying: ”Live view failed. There is a connection exception” (translated from Romanian).
How is this possible?

The setup:
Wi-Fi network <----- indoor station -----> HIK intercom switch <------> IP Cameras POE switch <------ Dahua NVR and IP cameras.

Thank you!

Great news!
Indoor station: DS-KH6320-WTE1
The problem was that, by default, this unit reads the mainstream of the IP cams and there is no way to change it. I even tried to change it in the XML file, but it always reverts back.

This is the only way to views live cameras on the HIk unit, Hik App and still have good quality on mainstream:

<?xml version="1.0" encoding="utf-8"?>
<MonitorInfo>
<MoniInfo>
<strRelateChannel>1</strRelateChannel>
<strDeviceName>Parcare interioara</strDeviceName>
<StreamMode>URL</StreamMode>
<strUrl>rtsp:/192.168.1.108:554/cam/realmonitor?channel=1&amp;subtype=1&amp;unicast=true&amp;proto=Onvif</strUrl>

</MoniInfo>
</MonitorInfo>

1. Set Onvif authentification to ”disable” on each camera (this is the downfall, but still ok in a controlled environment),
2. Ensure sub-stream is set to H.264 and resolution is no more than 720p.
3. Manually add cameras using the above XML.
Here is the magic:
<StreamMode>URL</StreamMode>
<strUrl>rtsp:/192.168.1.108:554/cam/realmonitor?channel=1&amp;subtype=1&amp;unicast=true&amp;proto=Onvif</strUrl>
