BI 5.2.9.6 - can't get substream for Amcrest IP5M

[pozzello]

So I picked up one of those cheapo 5MP cams (~$54 delivered with a code).

Amazon.com : Amcrest 5MP UltraHD Outdoor Security IP Turret PoE Camera with Mic/Audio, 5-Megapixel, 98ft NightVision, 2.8mm Lens, IP67 Weatherproof, MicroSD Recording (256GB), White (IP5M-T1179EW-28MM) : Electronics

It's a Dahua re-brand, so I figured the Dahua/Onvif-style URL for substream would work
(as it does for my other Dahua and Lorex/Dahua cams.) But BI doesn't seem to find the substream, tho ONVIF Device manager does (see attached).
the cam has the substream enabled (duh), was rebooted for good measure. I also rebooted my BI server for good measure as well.

Any idea? TIA, Paul.

Note URL used by ODM (after selecting substream profile) is the same as what I have for this cam's substream in BI:

Bi cam stats, showing this cam (Patio North) with no substream being pulled, while others (Lorex8MP and FrontEast) do, using the same url for substream.

Nevermind. I deleted the cam and re-added it, and now BI is pulling the substream as configured.
This cam entry in BI was re-used when I physically replaced the cam with another model and re-'find/inspect'ed for the new one (at a different IP).
That must have confused BI enough to not pull the substream when I added the secondary URL to it, for some reason.
May be a bug there somewhere, but OK for now...
