 ## DESCRIPTION
 
-Sends a MessageCommunication.ProvideCurrentStateRequest message and returns the response.
+The `Get-ItemState` cmdlet sends a "MessageCommunication.ProvideCurrentStateRequest" message and returns the response
+from the XProtect Event Server.
 
-The ProvideCurrentStateResponse contains a flat collection of ItemState objects representing the state of all known items in the site.
-Each ItemState contains an FQID, and State property.
-The FQID.Kind and FQID.ObjectId can be used to determine what type of object the state represents, and the ID of that object.
-
-Most of the time, you will probably only be interested in Camera objects, so you can filter the output with the -CamerasOnly switch.
+The `VideoOS.Platform.Messaging.ItemState` objects returned by this command have an `FQID` and `State` property, and
+using the `FQID` this command enriches the output by adding the item `Name`, `ItemType`, and `Id` as note properties.
