Not sure if anyone else found this document already, but its technical description of the RTSP implementation of the Hikvision devices
I suspect it was written for generic NVR, or maybe the 760x series, but it seems to match my DS-7108N-SN
For one thing, I learned the RTSP link:
rtsp://192.0.1.100:554/Streaming/Channels/101
but also a beauty like this playback of recorded streams:
rtsp://192.0.1.100:554/Streaming/tracks/101?starttime=20120802t063812z&endtime=20120802t064816z
and that the other often quoted address is old legacy and should not be used anymore:
rtsp://192.0.1.100:554/mpeg4/ch1/main/av_stream
User password is supported in the usual format:
rtsp://admin:abc12345@192.0.1.100:554/Streaming/Channels/101
