When you add TCP to an action set and the alarm occurs, Symphony connects to the address and port that you set in the action set and sends the message that you added to the Message field. The TCP command that Symphony sends is in the following format:
const char format[] = "<Action><Camera Id="camera_ID" Name="camera_name" /><Policy Id="policy_ID" Name="policy_name" /><UserString>user_string</UserString></Action>\n";
