ONVIF Key value

[edan]

Some cameras - the Dahua ones I have - generate ONVIF messages that have a "Key" value (as reported by ONVIF Device Manager). This key value for IVS messages seems to indicate the object type detected by the camera (e.g. "Objectid 6292" appears to be vehicles)

How can I set up an ONVIF rule in Blue Iris to detect these Key values?

Any help would be appreciated.

For anyone who stumbles across this post - I was wrong. The key value is a counter of some kind - it keeps incrementing, sometimes in jumps - and does not indicate the kind of item detected.
