There is no interface to ask for this in the Mobile Server and Mobile Server protocol so you will see it when there is no camera images.
The only ways I can see: Either ask for camera images and detect or in some way whether the camera is streaming or not or contact the XProtect system directly.
Hey Bo, thanks for the response!
I was hoping not to have to wait for images… What way would you suggest for ‘contacting the XProtect system directly’ ?
Directly in this case meaning not using the Mobile Server.
It is possible to create other kinds of clients that does not use the Mobile Server and mobile server protocol, but "directly " interfaces with Management Server, Recording Servers and Event Server like the Smart Client does (and in fact the Mobile Server service does).
A hybrid where you get images by Mobile Server protocol and get status information from Event Server is possible, but I am not sure how I like it, seems perhaps a little messy.
Let me know if you would like more information. Perhaps have a quick look at the StatusViewer sample.
