Hello,
If you go to the link below you can find some information on how to setup the rtsp url to hit a sub stream:
https://help.lorextechnology.com/link/p ... ur-DVR-NVRJust to note, selecting sub stream varies from camera to camera either through URL parameters, or other attributes of the URL; we can’t be sure how it’s done with Lorex, and it is best to present this question to Lorex support.
Also, ONVIF is there specifically to make this kind of thing easier, and all the available streams would be presented as a choice in a dropdown box, when connecting via ONVIF. Not sure if you have checked that.
Feel free to let us know if you have any other questions or concerns besides that, thank you!
Regards,
-Kevin
