Abstract: A monitoring system includes a sensor unit, a controller unit, a user interface unit, and a server unit. The monitoring system, through connecting the sensor unit with the user interface unit, transmits a data message from the sensor unit to the user interface unit. The user interface unit computes and generates a controller command message corresponding to the data message and a user setting. The controller unit receives the controller command signal through the server unit, wherein the server unit does not need to know the internet protocol addresses of the sensor unit, the user interface unit, and the controller unit ahead of time to be able to successfully transmit the data message and the controller command message.

Abstract: A data storage system includes a sensor unit, a storage unit, and a data exchange unit. The data exchange unit connects to the sensor unit and the storage unit, and transmits a data message received from the sensor unit to the storage unit, wherein the data exchange unit need not know the addresses of the sensor unit and the storage unit ahead of time to be able to successfully transmit the data message to the storage unit requesting the data message.
