DM368DVR-UD1

Hello!

I have DM368DVR-UD1.
I making own remote client module (UI and network program).

On the Internet I found:
    scheme://domain:port/cam/realmonitor?channel=&subtype=&authbasic=YWRtaW46YWRtaW4
    YWRtaW46YWRtaW4 - login+':'+password (Base64 decoder)
    For instance:
        rtsp://192.168.1.200:7620/cam/realmonitor?channel=1&subtype=00&authbasic=
        channel = 1 - is the first camera.
But it does not work with this DVR.

I can get video from the IP Camera, but I can't get the video from the DVR.
I don't know how to do it with this DVR.

I asked a similar question in the UD, but they have not responded.

Thanks.
