Here is a list of tested URLs for Hikvision IP Camera streaming and snapshots.

Main RTSP Stream:   
 rtsp://username:password@192.168.1.100:554/cam/realmonitor?channel=1&subtype=0?tcp

 rtsp://username:password@192.168.1.100:554/h264/ch1/sub/?tcp
  
Sub RTSP Stream:
rtsp://username:password@192.168.1.100:554/Streaming/Channels/2?tcp

or

rtsp://username:password@192.168.1.100:554/h264/ch1/sub/?tcp

JPEG Snapshot Main Stream:  
http://192.168.1.100/Streaming/Channels/1/picture

The RTSP stream works in Zoneminder and VLC for Hikvision IP Cameras. I have not tested the snapshot URL in Zoneminder.

Remember to change the username and password as well as IP address to match your setup. ?tcp is not needed, I use it to reduce corrupted frames.
