We’re trying to push events into Milestone with XML request body. we are in need to know exactly what modifications to be done in XML request body such that we receive pushed data in alarms preview window in the reference image shown below ?
In the Smart Client Alarm Preview some things are automatically included for display; snapshot images and related cameras.
I believe you will have to develop a alarm preview plugin, doing so you can ensure you show the information from the event the way you would like it presented.
Explore the Smart Client Alarm Preview plugin to see it in work.
Unfortunately you cannot get what you want by just sending another input with additional data on the event, it is the plugin that needs to have the new capability you want.
What you should do is to use the Smart Client Alarm Preview plugin sample as inspiration but develop your own plugin that does what you want it to do.
