Managing the subscription to event notification about changes in camera configuration

...

Example of subscription to event notification about changes in camera configuration:

Code Block
{ "track": ["hosts/Server/DeviceIpint.1"] }

Example of a message after subscription:

Code Block

{
   "objects" : [
      {
         "name" : "hosts/Server/DeviceIpint.1",
         "type" : "itemstatuschanged"
      }
   ]
}
{
   "objects" : [
      {
         "source" : "hosts/Server/DeviceIpint.1/SourceEndpoint.video:0:0",
         "state" : "off",
         "type" : "camera_record_state"
      }
   ]
}
{
   "objects" : [
      {
         "name" : "hosts/Server/DeviceIpint.1",
         "type" : "itemstatuschanged"
      }
   ]
}
{
   "objects" : [
      {
         "source" : "hosts/Server/DeviceIpint.1/SourceEndpoint.video:0:0",
         "state" : "off",
         "type" : "camera_record_state"
      }
   ]
}

where the type parameter will display displays the itemstatuschanged value when the configuration is changed.

Example of unsubscription to event notification about changes in camera configuration:

Code Block
{ "untrack": ["hosts/Server/DeviceIpint.1"] }

Example of a response message:

Code Block

{
   "objects" : [
      {
         "source" : "hosts/Server/DeviceIpint.1/SourceEndpoint.video:0:0",
         "state" : "off",
         "type" : "camera_record_state"
      }
   ]
}
{
   "objects" : [
      {
         "source" : "hosts/Server/DeviceIpint.1/SourceEndpoint.video:0:0",
         "state" : "off",
         "type" : "camera_record_state"
