Thanks. Had to check. cd /mnt/place/device/...

Yep, we just dated ourselves. I used it deliberately in the OP - we are
thinking of the same thing.
Pretty soon it will all be DLNA, but as I understand it the world hasn't
entirely gotten that far, yet. (But they're trying.)

In this case, I only became (re)aware of UPnP because the camera was
showing up in Windows networking and media centre as a net device, and
vlc / playlist / Local Network / Universal Plug'n'Play started listing them.
The cam won't accept a smb / ftp connection, but will put out to them.
Then I noticed it presents its files UPnP wise. Thus my search.

File sizes are apparently sent smaller FTP than SMB. It will not send
files to two places at once - e.g. local SD card and SMB. (It will send,
with the right incantation, two different files - i.e. one of live
footage / motion detection clip / movement log, in each of 2 directions
- but you get into priorities and conflicts - if it's sending live
footage one way, to send the clip the other would mean to interrupt the
live footage ...
It's a wee little beastie and can only do one such thing at a time.
Going to SD card, being local, will be the most pristine (fps wise).
Since it can't push, I was hoping to pull.

Yep, thought of that. I may be able to wireshark or tcpdump it, but I'll
have zero idea what to do with or about it.
By everything I have seen, it should 'just work'. I must be missing
something that with 20:20 hindsight will be stupidly obvious. No SSDP
running, something blocking, something ...
Thanks for anything that occurs to you.
