SYSTEM AND METHOD FOR REMOTE CONTROL OF LOCAL DEVICES OVER A WIDE AREA NETWORK
First Claim
1. A system for remote monitoring via an external network of the operation of a plurality of devices located on a local area network, the system comprising:
- a gateway module for coupling the external network with the local area network, the gateway module having a unique external network address and configured for receiving a network data packet addressed by the external network address, the gateway module configured for extracting a device data packet from the network data packet and for sending the device data packet to an associated local network address on the local area network;
a control server configured for coupling to the gateway module and configured for generating the network data packet to contain the device data packet associated with a selected device of the plurality of devices, such that the local network address is associated with the selected device; and
a controller module addressable on the local area network and coupled to the selected device, the controller module for receiving the device data packet according to the local network address and configured for operating the selected device according to the contents of the device data packet.

Abstract
A system and method for remote monitoring via an external network of the operation of a plurality of devices located on a local area network. The system and method comprise a gateway device, such as a server or intelligent router, for coupling the external network with the local area network. The gateway device has a unique external network address and is configured for receiving a network data packet addressed by the external network address. The gateway is configured for extracting a device data packet from the network data packet and for sending the device data packet to an associated local network address on the local area network. The system and method also have a control server coupled to the gateway via the external network and configured for generating the network data packet to contain the device data packet associated with a selected device of the plurality of devices. The local network address is associated with the selected device. The system and method also have a controller device located on the local area network and coupled to the selected device. The controller receives the device data packet according to the local network address and is configured to operate the selected device according to the contents of the device data packet.
