Hikvision SDK Smart Event Coordinate Data from Camera

Has anyone managed to get the coordinates of motion events from Hikvision IP Cameras? i.e. the X,Y, height and width of where the motion is occurring?
I realize this may not be possible with regular motion events, but I see a lot of references to it in the sdk regarding smart events.
So far I've only tried the windows version of the sdk.
Camera model in this case is a DS-2385G1-I

What I've tried so far:

Subscribing to alarms, both via SDK and ISAPI
This gets me what type of event occurred and occasionally some the rule parameters but no coordinates are ever attached.

Capturing Photos on VCA events and doing a smart search through sdk:
Camera doesn't support searching for photos by VCA events apparently

Streaming Live view and looking for metadata/VCA event frames:
I can turn on and off the rendering of the coordinates, but I never see any frame types other than headers and regular frames.


What else I plan to try:

Stream live view but on linux. Might work differently, who knows.

Rolling back camera firmware to see if a firmware update broke something maybe?

Any other suggestions are be appreciated.
 
they have support ISAPI metadata protocol where you can get all these metadata information including the coordinates information.
