IPC-HUM8230P-E1 - does anyone know the substream URL ?

[crw030]

Trying to set this particular camera up for substreams in Blue Iris v5.

However, even though the main stream works (/cam/realmonitor?channel=1&subtype=0), nothing appears to work for substreams even though this camera UI shows there should be two of them.

I have tried

• /cam/realmonitor?channel=1&subtype=1
• /cam/realmonitor?channel=1&subtype=2
• /cam/realmonitor?channel=2&subtype=0
• /cam/realmonitor?channel=2&subtype=1
• /live
• /cgi-bin/snapshot.cgi?1

Just curious if there is a way to determine what is being used either from the camera UI or if anyone happens to know something else I could try. At least in the UI I can click Main Stream, SubStream 1, Sub Stream 2 and I get in-browser image. I can't actually tell if anything is different about them.
